Crear una aplicación para Android

Hi everyone, I am looking for a developer with experience developing mobile applications that include VOICE CALLS between users. I will look for offers that include an application already working, so I can take a look from google play or apple store.


- Register process including credit card

- 2 types of users

- User1 will be able to search for user2 based on specific characteristics and has to be able to contact user2 from VOICE CALL.

- The quality of the voice call has to be perfect! Probably decoding, improvements will be needed.

- User1 should be able to qualify User2

- GPS / location will be needed to find users based on specific search

This is a general overview, all the details will be shared only with the selected developer. You can send high level estimate and we understand that could change based on the requirements.

Umiejętności: Android, HTML5, iPhone, Mobile App Development
