Build mobile Survey app Using API and SDK intergrations (PHP/HTML) -- 2

Build mobile Survey app Using API and SDK intergrations (PHP/HTML). I already have a backend built out but with different URL so bunch of php url's need to be updated first. 1. First step is to change all old file URL’s from [login to view URL] to instantsurveys.info. 2. Make updates to database to include the new following fields for members. Gender: DOB: Location: 3. Start work on app, see below for list of SDK’s and API’s we will be adding in to get surveys for our users. Also will be adding in rough UI look/feel. SDK’s To Add: API’s to add: Tap Research [login to view URL] Pollfish Cint Adscend Media Think action Theorem Reach 4. These will ALL be within our [login to view URL] tab, and setup as “Channels” I will be able to turn sdk/api ON/OFF so if I don’t want user to be able to see channel they won’t. (Already in php code) 5. We will have 5 screens (more details and image to follow below). a. Loading Screen b. Register/Login Screen c. Home Screen (Displays top bar & botton bar along with channels) d. Cashout/referral screen e. Account info screen. The app itself will have 3 tabs. Surveys, Rewards, Invite. I have a very good app already made called apptrailers has good UI i want to duplicate would it be best u redesign or if u get copy of code?
