The ultimate guide to building a mobile app
Got a great idea for an app? Need a new way to grow your business? We tell you everything you need to know about building a mobile app in 2020.
Mobile App Development is the creation and development of phones, tablets, personal digital assistants, and other devices that have operating systems. It involves creating software applications for the devices, such as games, utilities, and sometimes even simple to-do lists. These applications are created using programming languages such as HTML5 and JavaScript, which allow developers to create a good user interface. Mobile App Development requires both specific and hard skills from developers, from debugging existing applications to creating entirely new ones.
A great benefit of having a Mobile App Developer on your side is the knowledge and experience they can provide to make your business grow. In addition to creating mobile apps that are good for the user experience, Mobile App Developers can help you with backing up the data from your application securely, modifying an existing app to meet new requirements, troubleshooting any current issues in your application, setting up a server for your application and so much more.

Job Title: Senior Full-Stack App Developer for Debugging, UX Fixes, and Stability Improvements Job Description: I’m looking for an experienced full-stack developer to review and refine an existing mobile/web application that is already built and functional but needs polishing and technical corrections. The goal is to identify and resolve smaller issues that affect user experience, logic flow, and overall stability. This is not a project from scratch. The application is operational, but it requires a developer who can carefully audit the system, locate inconsistencies, and implement clean fixes. Responsibilities include: Reviewing existing frontend and backend logic Fixing UI/UX inconsistencies and interaction bugs Ensuring user actions trigger the correct outcomes across the pl...
I am rolling out a three-part bus transport platform and need an experienced Flutter developer to own the mobile side. The overall system will eventually include passenger, driver and conductor apps that talk to my existing REST API backend, but the very first milestone is the passenger experience. Passenger app – priority scope The passenger build must ship with: • Real-time bus tracking displayed on Mapbox maps • A smooth digital ticketing flow (QR / NFC hooks already in the API) • Trip planning that pulls live route and schedule data Mapbox is the mapping SDK of choice, so solid experience with its Flutter plugin is essential. You’ll wire up push notifications for bus arrival alerts, cache data aggressively for low-bandwidth corridors, and squeeze ...

I’m building an Android and iOS app that lets students and teachers at my tuition centre talk to each other easily and securely. After a quick sign-up or sign-in, the app must recognise whether the user is a student or a teacher and show the right interface, so proper role-based authentication is non-negotiable. Core communication features I need in version 1: • Real-time messaging – one-to-one and class group chats with push notifications, read receipts and simple file sharing (PDFs, images, voice notes). • In-app video calls – smooth, low-latency sessions for remote doubt clearing, built with WebRTC, Agora, Twilio or a comparable SDK. • Subject-wise discussion forums – teachers start threads, students reply, everything neatly threaded for late...
Project Title: Cross-Platform (Android & iOS) Automated Reward App "DinarX" - High Security & Local Iraq Features Project Description: I am looking for a professional Full-Stack developer (Expert in Flutter or React Native) to build/customize a dual-platform Reward App (Android & iOS) based on the Cash Rocket logic but with advanced automated features for the Iraqi market. 1. Cross-Platform Development (Android & iOS): Build a unified app for both Google Play Store and Apple App Store. Full Multi-Language Support: Professional localization in Arabic and Kurdish (Sorani) with RTL (Right-to-Left) alignment. 2. Automated Systems & Offerwalls: SDK/API integration for AyetStudios, Torox, and Lootably (Must work on both Android & iOS). 100% Automated Pos...
I have an idea for a “shnarps” style app that lets groups of friends create small, private tournaments where everyone puts real money into the pot and competes for the top spot. The entire experience will live on iOS only, and I picture a clean, modern-minimal interface that feels as intuitive as Apple Wallet: light backgrounds, clear typography, zero clutter. Here’s the core flow I’m after: a user downloads the paid app, signs up, invites friends to a tournament, each player stakes an agreed amount through an in-app wallet, play proceeds, and the winner (or top three, depending on settings we define) receives automated payout. Because we’re handling peer-funded prize pools, I need advice on the legal framework—what licences or jurisdictional restrictio...
I’m building a location-based social discovery platform focused on restaurant listings. The entire stack will rely on Supabase, so I need you to stand up and configure the Supabase backend—database schema, row-level security, authentication, storage, and REST/Realtime APIs—then hook it seamlessly to a clean, modern-minimalist interface. Core flow: a user signs up with email-and-password, grants location access, and instantly sees nearby restaurants. They can browse an infinite-scroll list, refine results through search and filters, and open a detail view with photos, description, and map pin. All pages must be fully responsive; the mobile web experience is the priority, and the desktop web view can surface a subset of features for simplicity. Deliverables • Supabas...
I need a Mixed Reality training application built and ready for first-pass testing as quickly as possible. The goal is a hands-on learning experience where users can interact with virtual elements that are accurately anchored in their real environment. Here is what I expect: • A functional MR prototype that launches on at least one mainstream headset (HoloLens, Magic Leap, or an OpenXR-compatible device). • Core scene demonstrating step-by-step instructional content, gesture or controller interaction, and basic performance tracking. • Clean, well-commented project files (Unity with MRTK or Unreal with OpenXR are both fine) plus a short read-me explaining build steps so my in-house team can iterate. The sooner you can deliver a testable build, the better. I am rea...
I’m building a white-label platform that any hospital, chain, or stand-alone clinic can adopt and brand as their own. Each organisation must be able to spin up an account, add unlimited branches as “children”, and still let the head office follow everything from a single parent dashboard. Three core user roles drive the system—Admin, Doctor, and Patient. Admins need the power to create additional custom roles, toggle permissions for every screen, and turn individual modules on or off so each client pays only for what they use. Doctors will handle appointment management, dive into patient case histories, and issue or update prescriptions directly from their phone. Patients, in turn, can book visits in real time, pull up their full medical history, and view current...
Saya ingin membangun sebuah aplikasi produktivitas ringan khusus iOS. Fokusnya adalah membantu pengguna membuat daftar tugas, menandai pekerjaan selesai, dan melihat statistik harian sederhana. Untuk tahap awal ini saya membutuhkan: • Sketsa alur layar (wireframe low-fidelity) yang memperlihatkan navigasi inti. • Draft desain antarmuka lengkap dengan panduan warna dan tipografi standar iOS. • Prototipe fungsional dasar di Xcode/Swift berisi: halaman daftar tugas, formulir tambah tugas, tombol centang, serta tampilan ringkasan. Kode harus jelas, terstruktur, dan mengikuti Human Interface Guidelines Apple. Setelah saya bisa menguji prototipe melalui TestFlight, kita akan membahas pengembangan lebih lanjut. Sertakan tautan ke aplikasi produktivitas iOS atau cuplikan...
I already have a Texas Hold’em scene running in Unity and most of the scripts are in place, but the betting system still needs polish. In particular, I can’t get the player-action flow (fold / call / raise) to behave consistently. The cards deal correctly, pots track, and UI elements are wired, yet once the betting round starts the logic sometimes breaks and user choices aren’t processed as intended. You’ll receive the existing C# scripts, my current prefab hierarchy, and a quick screen-recording that shows the problem in action. After reviewing the code you’ll adjust or rewrite only the sections that govern player actions; the rest of the game is stable and should remain untouched. Unity 2022 LTS and TextMeshPro are in use, so please be comfortable with th...
I am launching an e-commerce site for restaurants/bars and need it delivered entirely in Greek. The site’s main job is to let guests browse the menu, place an order online, and pay securely with a credit or debit card. Everything—buttons, system messages, emails—must appear in Greek, and the checkout flow has to feel effortless on mobile as well as desktop. I’m open to the platform you recommend (WordPress + WooCommerce, Shopify, custom Laravel, etc.) as long as it supports: • a clear product/menu structure with variants and add-ons • a reliable card payment gateway that works for Greek customers • real-time order confirmation to the kitchen and to the customer Nice-to-have features such as customer reviews or a loyalty program can wait until...

I have a promising ball-pool title in the works and now need someone who is ready to own the Android build from here through launch and beyond. The core gameplay is already framed out, but I want a developer who can refine the physics, tighten performance, squash lingering bugs, and help me push a polished, commercial-grade release to Google Play. Key features on the roadmap are multiplayer mode, fully customizable tables and cues, and a robust in-game currency system. All art and effects must feel authentic—think clean, realistic tables, balls, and lighting rather than a cartoon look. To set us apart from the crowd we will layer in special power-ups and a couple of fresh game modes that aren’t found in the usual eight-ball experience, so comfort designing and balancing new me...
I’m ready to roll out a completely free membership system that works seamlessly on my existing website and on companion mobile apps. The goal is to give users a single account they can create once, then use everywhere—no paywalls, no hidden tiers—just straightforward access. Here’s what I need help with: • A secure sign-up / log-in flow that syncs data between the web front-end and both iOS and Android builds. • A lightweight user-management dashboard on the back-end so I can view, suspend, or delete accounts without touching the database directly. • API endpoints (or GraphQL schema, if you prefer) that the site and the apps can call for authentication, password reset, profile updates, and basic analytics hooks. • Clean code and clear docu...
I run a service-based company and need a single application that works smoothly everywhere my customers and staff might be—on Windows PCs, Macs, iPhones, iPads, and Android phones or tablets. The core idea is simple: one code-base, one consistent user experience, deployed to desktop and mobile stores without sacrificing performance or a polished look. Here’s what I have in mind: • Desktop builds for Windows and macOS that install like native apps • Mobile builds for both iOS and Android, ready for App Store and Google Play submission • A clean, modern interface that matches our branding and remains intuitive for non-technical users I am flexible on the underlying stack, but frameworks such as Flutter, React Native + Electron, or any similar cross-platform t...
I’m looking for an Android developer who can build a lightweight calculator that handles the four basic operations—addition, subtraction, multiplication and division—and nothing more. The interface can be straightforward; it just needs to look clean on both phones and tablets and pass Play Console requirements without extra permissions. I will give you my AdMob App ID and individual Ad Unit IDs. Please wire them up so ads display properly in the released build and comply with Google policy. When you hand the project back, I need: • A signed, release-ready APK • The corresponding AAB file for Play Console • The complete, well-organised Android Studio source code Everything should compile out of the box and be ready for direct upload to Google Play. Le...
I’m in the very early stages of shaping a new digital initiative and would like a skilled freelancer to help me turn the rough concept into a clear, actionable plan and—once we agree on scope—carry it through to completion. At this point I’m deliberately keeping the canvas blank so I can benefit from your expertise in choosing the right approach, whether that ends up being a website, mobile app, design-led campaign, or a combination. You’ll help me: • Flesh out core goals and success metrics • Recommend the most suitable tech stack or creative direction • Produce a concise roadmap with milestones and deliverables • Execute the agreed-upon build or design work to a polished, launch-ready standard If you’re comfortable guid...
I’m looking for an experienced Flutter developer to review an existing Flutter codebase and help finalize the app. The app is already developed and the full source code is available. However, the UI implementation does not fully match the Figma design, and I want to make sure the codebase is clean, stable, and follows proper Flutter standards before moving forward. What needs to be done 1. Code Review • Review the existing Flutter project • Check overall architecture and code quality • Verify state management and navigation logic • Identify potential issues or bad practices • Ensure the project is maintainable for future development 2. UI Adjustments • Align the UI with the Figma design (pixel-perfect) • Fix spacing, padding, alignment, and typog...

I’m midway through a Unity project and need a developer who can jump straight into the existing codebase to refine and extend the game mechanics. The core systems are in place, but several mechanics still feel rough around the edges and a few new ones need to be added. All necessary models, animations, and prefabs are already prepared in organized folders, so your focus will be on scripting, balancing, and making the interactions feel tight and responsive. You’ll be handed a private Git repository with clear commit history and comments. After a quick walkthrough of the current architecture, I’ll outline the specific mechanics that require attention and share a checklist of edge-cases uncovered during internal playtests. Your first milestone will be to integrate the provi...
I want to build a polished mobile application that inspectors can use on-site, running smoothly on both iOS and Android from a single codebase. The heart of the product is fast, reliable photo capture: users must be able to shoot, review, annotate and attach media to each inspection point without ever leaving the app. Alongside that media workflow, the app should present ready-made inspection templates (civil, electrical, plumbing, etc.) while still letting the user design and save their own custom lists whenever they need something unique. A clean UI, offline operation with later sync, and one-tap PDF/HTML report export are important for day-to-day field work. Source code, build instructions and test builds for both platforms will be the final deliverables, ready for submission to the...
I’m building a fully-featured voice assistant that users can download on both iOS and Android. Think of it as a pocket-sized helper that can listen, understand, and act on spoken commands—setting reminders, fetching quick answers, controlling smart-home services via API, or triggering in-app actions. Here’s what I need from you: • A native or cross-platform mobile app (Swift/SwiftUI + Kotlin, or Flutter / React Native—whichever lets us land on both stores quickly and cleanly). • On-device and cloud speech recognition so the assistant responds within a second or two, even on slow connections. • Natural-language understanding: basic intent detection, entity extraction, and a fallback to a large-language-model endpoint when the user asks something ...

Idealnya kamu sudah berpengalaman memakai SDK iklan populer (AdMob, Unity Ads, dsb.) atau pernah menambahkan sistem pembelian dalam aplikasi pada game aksi multiplayer. Jika ada ide kreatif lain untuk mengh...
The design and code are ready; everything is in place. We just need to install the designs with minor adjustments to ensure smooth operation across all devices and to modify any unsuitable screens. Ideally, the developer should have experience with both iPhone and Android, and also be familiar with bank integration if needed. The design is ready and the code is ready — all files and code are prepared. We only need to implement the designs with small tweaks so the app works smoothly on all devices, and adjust any screens that aren’t suitable. The developer should have both an iPhone and an Android device, experience with bank integration if required, and know how to upload to the Apple App Store, Google Play Store, and Huawei AppGallery. We have 4 designs: - 2 in English: dark...

Orders flow in all day through the Swiggy partner app, and I need each one collected from the restaurant and handed to the customer fast, safely, and with a smile. The territory covers the entire city, so confidence weaving through traffic on your own motorcycle or scooter is essential. You’ll navigate exclusively with the Swiggy app, updating every stage in real time. Good manners at the door, accurate cash handling whenever a COD pops up, and strict compliance with traffic rules are all part of the job. Daily performance is gauged by on-time delivery percentage, customer ratings, and the total number of completed orders—hitting those targets keeps the work flowing. Deliverables each shift: • Exported delivery log from the Swiggy app • Accurate COD cash summary ...
The app uses react-native-video to auto-play clips inside a vertically scrolling feed on iOS. When a user scrolls rapidly, playback stops or freezes, even though the next row appears on screen. Everything else in the build is stable; the issue is isolated to this scrolling interaction. I will add you to the private GitHub repository so you can work against the existing codebase. You’ll find a clean branch, reproducible steps, and a short screen recording that shows the glitch. I’m happy to point you to the exact list component and the current optimisation attempts that didn’t pan out. Deliverable • A merge-ready pull request that keeps videos playing smoothly during fast scroll on iOS, with no regression on normal scrolling or memory usage. Acceptance is simple: r...
I have a brand-new mobile game that is ready for the world, but I need someone who knows the Google Play Console inside-out to take it from signed build to live listing and then keep it current. There is no existing store presence, so you will be starting from scratch: creating the listing, uploading the AAB/APK, configuring release tracks, setting up countries, pricing (free with in-app ads for now), and making sure the policy checks pass first time. Once the game is live, I want the same person to handle future updates—whether that means swapping in new screenshots, refining the description to improve ASO, or rolling out new versions through staged releases. Think of it as an end-to-end Play Store management role rather than a one-off upload. Key deliverables • Initial pub...
I am looking for an expert developer or agency to build a sophisticated Telegram Sales Bot that functions as a global marketplace platform. The bot will connect international customers with manufacturers via Telegram. The core of the experience should be a seamless blend of Conversational AI (customer support/sales) and a Telegram Mini App (TMA) (product browsing/checkout). Key Requirements & Features 1. Conversational AI (The Sales Agent): Multilingual Support: The AI must automatically detect the user's language and respond in their native tongue. Knowledge Retrieval (RAG): The AI must answer questions based strictly on a provided knowledge base (Product specs, quality details, logistics, shipping times from e.g. China, customs info). Persona: Professional, helpful, and sales-o...
I need native smartphone users currently located in Belgium, Taiwan, Colombia, Argentina, France, Mexico, Chile, or Spain to run a round of functional tests on our dual-service mobile application. The job is straightforward: First, install the latest build on both iOS and Android devices you own. Create a new account so I can verify that user registration works smoothly in each market. Next, move on to the two core journeys—booking a ride and ordering food. Complete each flow from start to finish, including payment (we provide promo codes so you will not be out of pocket) and cancellation where relevant. While testing, note every screen, button, message, and edge case that behaves unexpectedly or feels confusing, capture screen recordings or screenshots, and collect basic device lo...
I need an AI-driven mobile and web app that helps USMLE candidates sharpen their skills through full-length mock exams, real-time scoring, and granular performance analytics. The core of the product is an adaptive testing engine that selects questions based on the user’s weak areas, offers timed blocks that mirror the real exam, and presents a dashboard with section-by-section feedback, percentile comparisons, and study recommendations generated by the model. Because the primary goal is rapid release, I’m aiming for a working MVP as soon as possible, then iterative upgrades. In your detailed project proposal, walk me through the architecture you would use (AI model selection, question bank storage, scoring logic, analytics), the tech stack, and a sprint-by-sprint timeline that...
I’m looking for a developer who can build a production-ready Android application which is satta matka whose core function is a paid subscription system. The app will present users with two plan choices—weekly and monthly—and process every renewal through UPI, so the flow must be fully compliant with India’s recurring-payment guidelines. You’ll need to implement a clean onboarding screen that leads directly into the UPI checkout, enforce automatic access control based on the active plan, and surface a simple “Manage Subscription” area where users can upgrade, downgrade, or cancel at any time. Kotlin in Android Studio is preferred, but I’m open to Java if that speeds delivery and keeps the codebase maintainable. Please package the final APK...

I want a clean, lightweight mobile app that lets my students browse all of my Sanskrit books and teaching material in one place. The core of the project is a well-organised library where every title can be downloaded as a PDF for offline reading. Simple navigation, search by keyword or category, and a pleasant PDF viewer experience are essential because most users will spend their time studying inside the app. Alongside the digital library I also need a straightforward way for readers to buy a printed copy. When someone taps “Order Book,” the app should collect shipping details, hand off to a secure payment gateway (UPI, card, or any reliable provider you recommend), and confirm the order for both the buyer and me. An admin area where I can upload new PDFs, update prices, and ...

Users can sign up, explore categories like rings, bangles, necklaces, and earrings, view product images, descriptions, and live prices, and filter designs easily. The app includes a *Virtual Try-On feature* that lets users try jewelry using their camera or by uploading a photo. Customers can send enquiries for selected products and track their status. The *Admin Panel* enables the business owner to manage jewelry products, categories, prices, customer enquiries, and send notifications for new designs, offers, and updates.
I plan to launch a small yet robust mobile application that runs smoothly on both Android and iOS. The core of the project is straightforward: users must be able to see sports related details, products and pay seamlessly for subscriptions and products.
