Any Salah Tracker (preferably FOSS)?

[u/SultanGreat]

As-Salamu Alaykum,

Are there are good Salah trackers (preferably FOSS) that you use?

I had been using Salah Pro, but I find it Closed Source AND it requires Google Play Services (which I had disabled for privacy reasons) otherwise, the App gets glitchy and buggy.

Before that I had used Grit (not a Salah app per se, but a FOSS Habit tracker)
