Really nice app. And push notification work! Weee (turn them off and on again). The app doesn't follow UT guidelines in sone places. For the rest? First place in DeltaChat train. Thank you!

I don't really use this app but I'm really impressed by the quality and the features it has. It even has QR codes to login on another device. It's really cool. I wish many more apps like this appears on Ubuntu Touch. Thanks to the developer 😄

Successfully imported my backup from Android! Everything including data from my TOTP mini app was there. Notifications work reliably after preventing app suspension via Tweak tool.

Works very well and does 1:1 chats or groups. Many more features like integrated mini apps e.g. checklist or calendar.

It works great and I hope you continue developing it. How can I maintain timely notifications when the application is closed?
