Add a feature using Rest API to my Ionic App -- 2

NOTE: ONLY APPLY IF YOU FIT THE BUDGET LIMIT AND CAN COMPLETE IN 1 DAY I need a feature to be added in my already existing mobile app built on ionic and the app is linked to my WordPress website. The app I am using is [login to view URL] The WordPress site has a plugin which provides an option to login, signup, forgot password using phone number and users can also edit the number from their profile. This plugin even has Rest API, so using that same features can be implemented to mobile app aswell. So to be precise the feature just needs to be linked with app, nothing needs to be built from scratch. Both the app and the plugin I am using on WordPress are having proper documentation including RestAPI documentation You also need to - Need to change the flash screen - Need some text changes in the app Please don't waste my time or your time by bidding something unreasonable as being a developer myself I know how much time and resource it will take. Please include I read the proj desc in your cover letter so I can make sure you read this all.
