Alarmio VS simple-qr

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.

Probably your list does not need another Barcode scanner, but have you looked at the following? Simple QR It's also available in the Google AppStore: Simple QR

I did not create an example project to demonstrate this structure, but you can take my Ionic app - Simple QR as a real-world reference.
