I have developed many apps on Android and ios using phonegap and native environment.
I am pretty confident to develop your app with your desired features and functionality.
You may see the apps I developed for various clients available at Google Play Store.
I had made taxi app, gps tracker, game app, social app, chat app, photo editor app,
photo sharing app like instagram, spy app. as an android app and game developer,
i can say that your project is pretty easy for me to handle..give me a chance and see what i can bring as result..
