We are looking for developers to build a mobile app (Android and iOS).
The app is a mobile version of SNS (a web platform for survey analysis made by us).
Attached you can see detailed briefing.
The web portal and admin area is alrady done by our internal team, and the API REST will be provided by us.
Please let me know your questions, your time estimate, and final price.
We are open for suggestions regarding technology and framework.
