Syncing your chats between all your Apple devices is super easy. Here's how -
- Sign into your iCloud account on one device (iPhone, iPad, Mac)
- Launch Chatster and start a conversation
- Sign into the same iCloud account on another device (if not already signed in)
- Launch Chatster and tap on the menu at the top right of the chat screen and select "Chat History"
- You should see the conversation you started from the first device in the list
All of your conversations on either device will now sync up going forward.
