To make video chat a dream.
Choose a platform: iOS or Android.
Designing and drawing the main application screen (necessary minimum: a screen chat list and chat screen). If you are strongly imbued with the communication of the future, do not be shy and boldly draw an interface for video call!
Constitute a transition diagram application (screenflow). (Not designed screens can be shown as empty boxes).
