Nisaa

Nisaa is a period-tracking app for Muslim women who need their cycle tracking to reflect Islamic rulings on prayer, fasting, and purity rather than a generic health app. It is trusted by more than 25,000 Muslim women and is also available in a pregnancy-focused version.

A user logs bleeding and Nisaa names the religious state it corresponds to, including spotting, brown discharge, or istihadah, and chooses a madhab, Hanafi, Shafi'i, Maliki, or Hanbali, so every ruling follows that school consistently. Users can import past cycle history from Apple Health, Flo, Clue, and other apps during setup instead of starting predictions from zero.

The app shows day by day when prayer lifts and resumes, when ghusl is due, and tracks every missed Ramadan fast so it can be ticked off as made up, even years later. Nisaa AI answers cycle and worship questions in the user's own words, drawing on classical fiqh sources and the hadith behind them, and the app states it is a study aid rather than a substitute for a qualified scholar.

Nisaa is available on Google Play for Android 8 or later and on the App Store for iPhone and iPad with iOS 16 or newer. Nisaa Pro is a paid subscription with pricing and any free trial shown before purchase, and the company states it does not sell or share cycle data with advertisers.
