salam wa alaykum,
first of all, the app is amazing. may Allah reward you for bringing Islam into peoples lives in such a convenient and easy way. as the app grows in the future i hope to see some improvements including:
a widget / reminder for the ayah of the day. similar to how we get notifications for salah times, but instead for ayahs too.
another improvement which would be significant is allowing the salah tracker to have different features that include (missed salah and if a sister is menstruating that week).
thank you for all your hard work! JAZK
