HeyChat! - Voice and text messaging app

Description

I have started my own store where I am selling quality apps with amazing features. If you are interested for a golden product, check it out.

Fast, well-designed and with voice messaging feature makes this app more interesting with alot of other great features. With this application, you can talk using text or voice with anyone and everyone. The app is fully designed and is cleanly coded to make it easier for buyers/developers to understand the code and modify whatever thing they want. You can find friends, add them and start talking with them either by text or voice. Most amazing thing about this project is that it can be altered easily and more features can be added without authors advanced guide. The app works together with PHP and MySQL on server-side and SQLite and Sinch on client-side.
