# Chat — Mobile app

The one-to-one or group messaging screen, handling keyboard behaviour, message input, media sharing, and real-time updates in the constraints of a mobile screen.

## Items

### Keyboard push-up
The message input bar rising with the keyboard when it opens, so the conversation history is not obscured

_Tip: The behaviour differs between iOS and Android, so explicit handling on both platforms is what prevents the common bug of the keyboard obscuring the input bar_

### Input bar
A persistent input bar at the bottom of the screen containing a text field, send button, and media attachment option, thumb-reachable in all grip positions

### Message bubbles
Sent messages on the right, received on the left, consistent with every messaging convention the user already knows

_Tip: Breaking the sent-right received-left convention for a design reason is rarely worth the disorientation it causes_

### Swipe to reply
Swiping a message right revealing a reply-to action, threading the response to the specific message

### Long press message actions
Long pressing a message opening a reaction picker and action menu e.g. react, reply, copy, delete

### Read receipts
Sent message status shown as subtle indicators below or within the message bubble (sent, delivered, read)

### Media and file sharing
Images, videos, and files shareable directly from the input bar, with inline previews in the conversation thread

### Typing indicator
An animated indicator when the other party is composing

### Scroll to latest
When new messages arrive while the user is scrolled up, a button to jump to the latest message
