Muslims: Recommend Privacy-Friendly Muslim Apps? (Azan, Qur'an, Athkar, etc)

I highly recommend Salah Flow for prayer times and prayer tracking, I think they are currently only on Apple (sorry Android users), but if you don’t create an account, all the data is stored on-device and private. They just came out and unlike other apps out there, it has no ads and is also free, such a gem. You can also maybe check their website, it’s Salahflow.com
