Context
A prayer app meets its user five times a day. At that frequency, every needless notification and every crowded screen becomes a weight. We built Mümin 360 to lift it: times, qibla, Qur'an and dhikr in one place, plain and quiet.
Approach
In Türkiye, prayer times come from the data published by the Presidency of Religious Affairs (Diyanet); abroad they are calculated with the Diyanet method, or another method if the user prefers. Without a connection, times are calculated on the phone. A notification arrives when the prayer time begins and fifteen minutes before; its text is drawn from sourced verses and hadith, and the app stays silent during quiet hours. There is no account and no server: prayer records, the journal and intentions never leave the phone. We call the design Gökkubbe — the sky dome — and the colour of each screen comes from the sky at that prayer time.

What we have written about it
- Qibla How does a qibla compass work, and why does it drift? A phone's qibla is an angle worked out from your location, laid over the north its compass finds. Drift mostly comes from magnetic declination and nearby metal.
- Prayer times How are imsak and iftar times set? Safety minutes explained In the Diyanet calendar, imsak is true dawn at 18° and iftar is sunset plus a 7-minute safety margin. Why Ramadan timetables differ, and how to check yours.
- Prayer times How to choose a prayer times app: 10 things to check The best prayer times app takes its times from the right source, asks for few permissions and shows no ads during worship. Ten checks and a five-minute test.
- Prayer times How are prayer times calculated abroad? A high-latitude guide Abroad, prayer times depend on whether your city is on Diyanet's list and on your latitude. The 45th-latitude ruling, high-latitude rules and a decision table.
- Studio note Studio note: why Mümin 360 needs no account and no server In Mümin 360 3.0 we removed our own server and remote push. Worship records stay on the phone. Why we did it, what it cost, and what still goes online.
- Prayer times Why do prayer times differ from one app to another? When two apps show different prayer times for the same city, the cause is usually method: the sun's angle, safety minutes and the Asr rule. A worked example.
- Mobile apps How in-app purchases and subscriptions work In-app purchases and subscriptions: App Store and Google Play rules, one-off purchase or subscription, commission, refunds and a note on tax.
- Studio note Studio note: what do we leave out of a prayer app? What we deliberately left out of Mümin 360: ads while reading the Qur'an, nagging notifications, unsourced religious text, comparison and dark patterns.
- App Store Why does the App Store reject apps? The 10 most common reasons App Store rejection reasons mapped to Apple's guideline numbers: incomplete builds, demo accounts, screenshots, privacy, account deletion and more.

Frequently asked questions
Is Mümin 360 free?
It is free to download. The Qur'an, duas, the dhikr counter, prayer times, adhan alerts, the qibla, the Heart Journal, khatm plans and worship and missed-prayer tracking are free for everyone. Optional Premium adds comforts such as an ad-free experience and extra adhan and alert sounds.
Where do the prayer times come from?
In Türkiye, times come from the data published by the Presidency of Religious Affairs (Diyanet). Abroad, the Diyanet method is the default, and MWL, ISNA or Umm al-Qura can be chosen instead.
Do I need an account?
No. Mümin 360 has no accounts and never asks for a name, email or phone number. Worship records, the Heart Journal and dhikr counts stay on the phone.
Does the app show ads?
The free version does. Ads 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, and with Premium the ad software never starts.
Does it work offline?
Yes. Without a connection, prayer times are calculated on the phone. Downloaded surahs can be read and heard offline, and alerts need no connection because they are scheduled on the device.
Which devices does it run on?
Mümin 360 is on the App Store for iPhone, in Turkish, English and Arabic. There is no Android version for now. Its full name, to tell it apart from apps with similar names, is Mümin 360 - Namaz Kıble Zikir.
