Alarmio VS SchildiChat-android

I am aware of it. On Google Play you may encounter money demand, but in F-Droid or GitHub releases you just simply cannot. Note that Alarmio is not still maintained but when I tested it I did not encounter any issues with it, so I acknowledged polished experience rule.

On Google Play it is not but on F-Droid and GitHub it is.

Then you don't have to lock your phone to disable it. The fact that it hasn't been updated does not bother me. It is just an alarm clock which functions properly at least in my phone. But I can understand if you don't want to use it. In such a case, you can try Alarmio, Clock+, or Simple Alarm Clock.

If you are on Android, give Schildichat a try. It is available on Fdroid. It is a fork of Element. These are the main changes from Element. There are aslo other clients here.

The most obvious one is that all chats can be in one tab https://github.com/SchildiChat/SchildiChat-android/blob/sc/FEATURES.md

follow the instructions here https://unifiedpush.org/users/distributors/gotify/. Use either fluffychat or test version of schildichat https://schildi.chat/android/ stable schildichat wont work with unifiedpush since it's not implemented in it yet.
