I need a source code for Chat App for iOS and Android. Like a "Viber" or "Whatsapp".
Features that it must have:
1) For both iOS and Android
2) XMPP or any other server technology (must not depend on parse or any other service that charges fees)
3) Login using phone number
4) Add chat contacts from Address Book via phone numbers
5) Profile settings
6) Delete my account
7) One on one chat
9) Group creation/chat
10) Send voice
12) Number of unread messages are shown next to a chat
13) Alerts (push notifications with sound)
License should be in perfect order and allow us to use it commercially in at least one end product without any hidden secret fees later etc.
