I was recently recommended this app due to there being no ads as well having a tracker for missed fasts as well as prayers. However, I can see an issue coming up where when I get a new phone or the app crashes for some reason, I will no longer have my missed days tracked. It would be absolutely amazing if there could be an account we would make to save this data so that we don't have to worry about losing it. Because I feel like the tracker loses its reliability for this and I will still need to keep track of my missed fasts the way I was beforehand, which makes this current feature pretty much useless overall. So, adding a account-based feature would make this app so much more impressive. I hope this is at least considered for future updates!
