How to choose a prayer times app: 10 things to check
There is no single “best prayer times app” for everyone, but a handful of checks will find the right one for you. A good app takes its times from a clear source, asks only for the permissions it needs and doesn’t force you to open an account. It shows no ads on the screens where you pray or read, its alerts arrive on time, and it doesn’t publish religious text it cannot source. Most of these ten checks take five minutes.
We write this as a studio that builds a prayer app of its own. We assess our app, Mümin 360, against the same checks at the end — openly, gaps included. We don’t name other apps here; the checks work on any app in the store.
Which is the best prayer times app?
The best app is the one that matches the calendar you follow and treats your data with respect. In Türkiye that is usually the calendar of the Presidency of Religious Affairs (Diyanet). Elsewhere, a good starting point is to ask which calendar your local mosque uses.
A store rating on its own tells you little. A high score can reflect a pleasant interface, but it says nothing about how the times are calculated or where your data goes. So we’d check the points below before looking at the stars.
Ten checks: what to look at, and how
We’ve put every check into one table:
| # | Check | How to check | Good sign |
|---|---|---|---|
| 1 | Source of the times | Settings or the store description | Source and method stated plainly |
| 2 | Asr and safety-margin settings | Compare with your mosque’s calendar | All six times within a minute |
| 3 | Location permission | The first permission prompt | “While Using the App” is enough |
| 4 | Account requirement | First launch | Usable without an account |
| 5 | Where and how ads appear | Qur’an, qibla and dhikr screens | No ads on worship screens |
| 6 | Privacy label | “App Privacy” on the App Store page | No data used to track you |
| 7 | Offline use | Open it in aeroplane mode | Times still show |
| 8 | Reliable alerts | Wait through one prayer time | On time, with a choice of sound |
| 9 | Sourced religious content | Under each dua or hadith | Source and reference given |
| 10 | What sits behind the paywall | The subscription screen | Times, qibla and the Qur’an stay free |
Each check is explained briefly below.
Do the times come from the right source?
The first and most important check is where the times come from. An app may take them from an official table or calculate them itself with a method. Either can be right, but the app should say which it uses.
When two apps show different times for the same city, the cause is usually the sun’s angle, the safety minutes or the Asr rule. We walk through a real İstanbul example in why prayer times differ between apps. Watch the Asr setting in particular: the option many apps label “Hanafi” can put Asr more than half an hour after the Diyanet calendar.
Which permissions does the app ask for?
A prayer app needs your location, but not constantly in the background. According to Apple’s Location Services page, an iPhone offers four choices: “Never”, “Ask Next Time Or When I Share”, “While Using the App” and “Always”. “Always” grants access even while the app is in the background.
“While Using the App” is enough for prayer times and the qibla. It should also be possible to pick your city by hand and grant no location access at all. If a prayer app asks for your contacts, photos or microphone, stop and ask why.
Do you need an account?
You don’t need an account to see prayer times. Guideline 5.1.1(v) of Apple’s App Review Guidelines asks that apps without significant account-based features let people use them without a login. The same guideline says apps may not require personal information that isn’t directly relevant to their core function.
An account means your worship records live on a server. Under Article 9 of the GDPR, data revealing religious beliefs is a special category of personal data, and Turkish data-protection law treats it the same way. That is why keeping records on the phone feels right to us. We explain what that gives you in what is a local-first app.
Where and how are ads shown?
A free app paying its way with ads is understandable. What matters is where the ads sit and what kind they are. An advert that appears while you read the Qur’an, find the qibla or count dhikr breaks the very moment the app exists for.
Look at two things. First, whether ads appear on worship screens. Second, whether the app asks permission to track you. If it asks “Allow app to track your activity?”, it wants to personalise adverts to you. Apple’s privacy page explains that apps must ask before tracking you across other companies’ apps and websites.
How do you read the privacy label?
Every App Store page carries a privacy summary based on the developer’s own declaration. Apple’s developer documentation says it shows the types of data an app may collect, and whether that data is linked to you or used to track you.
Read it in this order:
- If there is a section on data used to track you, see what it lists. For a prayer app you’d expect it to be empty.
- In the data linked to you, look for location, contact details or usage data.
- Compare the label with the app’s privacy policy. A policy that lists each request and where it goes is a good sign.
Remember that the label is self-reported. Apple does not measure it directly; keeping it accurate and current is the developer’s job.
Do alerts arrive on time — and why isn’t the full adhan played?
Arriving on time is a prayer app’s real job. Alerts scheduled on the phone work without a connection. Focus modes, Low Power Mode or switched-off notification permissions can still delay or silence them.
People often ask why the adhan isn’t played in full with the alert. The reason is iOS itself. An Apple engineer’s reply on the developer forums confirms that a single notification sound cannot be longer than 30 seconds. So on an iPhone, an adhan played with an alert is either a shortened recording or its first thirty seconds. Treat any app that claims to play the full adhan as an alert with some care.
Is the religious content sourced?
A dua, hadith or guide should be published with what it rests on. Verses need their surah and verse number; hadith need their source collection. Text offered as a “well-known saying” without a source is the quickest way for a prayer app to lose trust.
Be wary, too, of an app that gives firm rulings on matters of fiqh. A good app points such questions to a qualified body — in Türkiye, Diyanet’s High Council of Religious Affairs — or to your local imam.
What does the paid tier cover?
Many prayer apps offer a free version and an optional subscription. The question is whether worship itself is locked behind it. Prayer times, the qibla and the Qur’an should stay free; charging for comforts such as an ad-free experience or extra adhan voices is reasonable.
The subscription screen should state the price and renewal terms plainly. A fake countdown or a “last chance” screen is a warning sign. We cover what the store rules say in in-app purchases and subscriptions.
A five-minute test
After installing an app, you can judge it quickly:
- Note whether it asks for an account on first launch, and which permissions it requests.
- Compare its times with your mosque’s calendar, or with Diyanet’s prayer times page, which also lists cities abroad.
- Open the Qur’an, qibla and dhikr screens and look for ads.
- Switch to aeroplane mode and reopen the app. Are the times still there?
- Read the privacy section on its App Store page.
How does Mümin 360 measure up?
We apply the same checks to our own app, gaps included:
- Source of the times: in Türkiye, times come from the data Diyanet publishes. Abroad, the Diyanet method is the default, and MWL, ISNA or Umm al-Qura can be chosen.
- Permissions and account: there is no account, and no name, email or phone number is asked for. You can choose your city and district by hand.
- Ads: the free version shows ads; we don’t hide that. They are always requested as non-personalised, and the app never asks to track you. There are no ads on the surah reading, dhikr counter, qibla or Heart Journal screens. With Premium, the ad software never starts.
- Data: worship records, the Heart Journal and dhikr counts stay on the phone. Every request that goes online is listed in our privacy policy.
- Offline and alerts: without a connection, the times are calculated on the phone. Alerts are scheduled on the device and arrive when a prayer time begins and fifteen minutes before.
- Paid tier: the Qur’an, duas, dhikr, prayer times, adhan alerts and the qibla are free for everyone.
- The gap: for now the app is iPhone-only. There is no Android version.
We explain the thinking behind these decisions in what we leave out of a prayer app.
Frequently asked questions
Why does a prayer app want my location?
Prayer times are calculated from your latitude and longitude, and the qibla direction depends on where you are. “While Using the App” is all it needs. If you pick your city by hand, you can get accurate times without granting location access at all.
Is there a prayer app without ads?
Yes. Some apps are entirely free of ads, and others remove them with a paid option. In an app that does show ads, the thing to check is whether they appear on worship screens and whether they are personalised.
Why doesn’t my iPhone play the full adhan with the alert?
iOS does not allow a single notification sound longer than 30 seconds, so the adhan in an alert is a shortened recording. To hear it in full, use the player inside the app itself.
Why are the times a few minutes off my mosque’s calendar?
The gap usually comes from the calculation method, the safety minutes or the Asr setting. The distance between a city centre and your district can add a few minutes too. The details are in why prayer times differ between apps.
