The Problem
The client needed a working chat and calling app fast, without building and running their own messaging and VoIP servers.
What We Built
Phone login. Digits SDK verifies the number, so there is no password.
Chat. Parse backend, phone contacts, conversation list and an emoji keyboard.
Voice calls. Sinch calling with incoming-call and in-call screens.
Push. GCM wakes the app for new messages and calls.
Admin app. A second Android app listing active and deleted users.
A Note on the Image
Client contract, 2016. Screens are redrawn from the app layouts with its own buttons; names and messages are sample data.
