We are still working on developing MLS group chat, and after completing this task, we will evaluate Amber login. Since Keychat uses the Flutter development framework, it supports both iOS and Android versions, but Amber seems to only have an Android version. In any case, we will consider it. 

 Just an FYI, this is the only reason I'm not using keychat  

 Thank you for the feedback. 

 By when a IOS version? 

 We estimate it will take 1-2 months.
