What is the best period tracker for Ramadan?

During Ramadan a period tracker has one job a generic calendar app was never built for: telling you, in the moment, whether that day's fast is being counted or will need to be made up, and keeping an accurate tally as the month goes on. A few things separate a tracker that actually does this from one that just marks a date.

• It should log the exact moment bleeding starts or stops, not just the date. A fast breaks the instant bleeding begins, even if that is minutes before Maghrib, and purity returning after Fajr still leaves that day owed as qada. A tracker that only records "today" loses exactly the detail that decides which of those applies to you.
• It should tell hayd apart from istihadah before you skip a fast you did not need to. Not all bleeding during Ramadan is hayd, and istihadah does not invalidate the fast the way a period does. Spotting near iftar is exactly the moment a tracker built for this should help you name correctly, rather than leaving you to guess between breaking a valid fast and continuing an invalid one.
• It should keep a running qada count that survives past Ramadan. Every fast missed to hayd or nifas is owed before the next Ramadan, the majority of scholars set that same deadline for making them up, and missing it without a valid excuse carries its own ruling on fidya. A count that resets every year, or that you have to reconstruct from memory in Sha'ban, is not built for a debt that can carry across more than one Ramadan.
• It should not go quiet on worship the moment your fast pauses. The days you are not fasting are still Ramadan: dhikr, dua, istighfar and charity remain open to you, and depending on your madhab so does reciting Qur'an without touching the mushaf. A tracker that treats those days as a blank space misses most of what is actually available to you in them.
• It should not sell what it logs, and Ramadan is not the month to overlook that. In 2023 the U.S. Federal Trade Commission ordered the maker of the period tracking app Premom to stop sharing users' health data with Google and other companies for advertising, and a separate review of popular period and ovulation trackers by the Mozilla Foundation found most collected far more than they needed. A record of your bleeding layered with a record of when you fasted, prayed or paused says more about your religious practice than either fact on its own.

Nisaa was built around the first three points specifically for Ramadan: it timestamps bleeding as you log it rather than just the day, names your state as hayd, istihadah or tahara using the position of the madhab you choose, and keeps a running total of the fasts you still owe across Ramadans. If you are taking period delay pills for Ramadan to avoid this altogether, the same logging habit is what tells you whether breakthrough spotting on the pill is hayd or nothing at all. If that is what you need this Ramadan, it is on the App Store.
