How to choose a prayer times app

Run each question below against any app's App Store page and its settings. A good prayer app answers "yes" to most of them plainly; an app that dodges the questions is telling you something too.

1. 1Does it tell you its calculation method?

   Fajr and Isha depend on a twilight angle that different authorities set differently, so a few minutes' variation between apps is normal. An app that names its method (and lets you change it) is being straight with you; one that hides it is asking you to trust a black box.

2. 2Can it match your mosque, or only calculate?

   A calculation is a baseline. Your mosque rounds the adhan and sets its own iqamah, so the board on the wall differs from any formula. The best apps let you follow your masjid's actual adhan and iqamah — not just a computed time near it.

3. 3What does its App Store privacy label say?

   Open the app's App Store page and read 'App Privacy'. Does it collect location, contacts or usage and link it to you? Does it show ads or embed trackers? A prayer app has no need to sell your data — the label tells you whether it does.

4. 4Is it honest about the Qibla compass?

   Phone compasses drift near metal and magnets, and many people never see the calibration warning. An honest Qibla says so — it withholds the arrow when it can't be trusted and offers the true-north bearing or the sun instead, rather than pointing you confidently wrong.

5. 5Does it forgive a missed day?

   Streaks can motivate, but a streak that resets to zero the first hard day quietly punishes you for being human. Look for a design that leaves room for mercy — one missed day shouldn't erase a month.

6. 6Does it work on your device, without an account?

   Prayer times, Qibla and reminders can all run on-device. If an app makes you create an account or sends your location to a server just to tell you when Maghrib is, ask why. Less data leaving your phone is better.

7. 7Does it actually help you pray — or just notify you?

   A reminder you swipe away mid-scroll doesn't help much. The question is whether the app helps you act on the time — for instance by quieting the apps that usually steal your prayer window until you've prayed.

Why the calculation method matters most

If you only check one thing, check whether the app names its method — and whether it uses the one your community follows. The difference between, say, the ISNA angle used across North America and the Muslim World League angle can be ten or fifteen minutes on Fajr. An app that quietly uses the "wrong" convention for your country isn't lying, but it isn't matching your mosque either. We wrote a plain-language explainer on how prayer times are calculated and why your app doesn't match your mosque if you want to go deeper.

Privacy is a feature, not fine print

A prayer app touches something personal five times a day. It has no legitimate need to show you ads, track you, or sell your location — and the ones that do are quietly funding themselves with your attention. The App Store privacy label makes this checkable in thirty seconds. We wrote more on telling a private prayer app from one that monetises you.

A note on scope

This is a practical buying checklist, not a religious ruling and not a review of specific apps. For questions about which calculation method or Asr position to follow, ask your local imam.

Questions people ask

What should I look for in a prayer times app?

The essentials: it names its calculation method and lets you change it, it can match your mosque's actual adhan and iqamah rather than only calculating, its App Store privacy label is clean (no ads, no trackers, nothing sold), and its Qibla is honest about compass error. Bonus: it runs on-device without an account and helps you actually pray, not just notifies you.

Why do prayer apps show different times?

Mostly the calculation method — different authorities set the Fajr and Isha twilight angles differently, and the Asr position (Shafi vs Hanafi) changes the afternoon time. A few minutes' difference between two honest apps almost always traces to these choices, which is why an app that states its method is worth more than one that hides it.

Is a free prayer app safe to use?

Free isn't the question — how it pays for itself is. If a free app shows ads or sells data, you're the product. Check the App Store privacy label. A paid or trial-based app with a clean label is often the more private choice, because it doesn't need to monetise your attention or location.

How does ImanKeeper measure up to this checklist?

ImanKeeper names its method and lets you change it, matches your mosque's real adhan and iqamah, runs on-device with no ads and no tracking, keeps an honest Qibla, has a forgiving streak, and quiets distracting apps during your prayer window — it was built to pass this checklist rather than fake it.
