Prayer time app development
Prayer time app development with reliable times, Qibla and adhan
For a prayer app, being on time is the whole promise. Users rely on it for fajr in the dark and for maghrib at a specific minute. That depends on correct calculations, the right location and notifications that actually arrive when the phone is asleep.
Theme29 builds prayer time and Qibla apps for iOS and Android in Flutter. Zabi, our Islamic companion app, includes customisable, location-based prayer times, a Qibla finder, a nearby mosque locator and a Ramadan schedule with Iftar and Suhoor times.
How prayer times are calculated
Prayer times come from the sun's position for a given place and date. Communities agree on most of this but differ on a few conventions, so a good app lets users choose.
Calculation methods
Common methods include the Muslim World League, ISNA, the Egyptian General Authority of Survey, Umm al-Qura and the University of Islamic Sciences, Karachi. They differ mainly in the angles used for Fajr and Isha.
Asr and juristic choice
Asr begins earlier or later depending on the school of thought followed (the standard or Hanafi convention). The app should offer both, with a clear label.
High latitudes and adjustments
Far from the equator, twilight may not fully end in summer. Recognised fallback rules exist and users can also apply manual minute adjustments.
Local timetables come first
Many mosques publish their own timetable. Letting a mosque or region override calculated times keeps the app consistent with the community. The person or committee responsible decides which source is authoritative.
Location, notifications and Qibla, done reliably
Location and time zones
Automatic location with a manual city fallback for privacy, correct time zone and daylight saving handling, and support for travellers.
Adhan and reminder notifications
Notifications and adhan audio need careful platform-specific work. For example, iOS limits how many local notifications an app can schedule at once, so the app must reschedule continuously.
Qibla finder
Direction is computed from the user's location to the Kaaba, then shown with the phone's compass. Sensor calibration prompts and a fallback map view help where the compass is unreliable.
Mosques, Ramadan and the Hijri calendar
A nearby mosque locator (Zabi searches a 1 to 5 km radius), Iftar and Suhoor times for Ramadan, and a Hijri calendar with an adjustment option for local moon sighting.
Why it is worth investing in the details
Users trust it
A prayer app that is right, every day, becomes a habit.
It respects local practice
Method, Asr and manual adjustment settings mean users are not forced into someone else's convention.
Works across devices
Notification behaviour is tested on real Android and iOS versions, not assumed.
Privacy-conscious
Location is used for the feature and handled with clear explanations.

How a prayer app project runs
- 01
Decide defaults and sources
Which methods, Asr conventions and regions the app supports, and whether mosque timetables will be included.
- 02
Build and verify the calculation
Times are compared against trusted timetables for several cities and seasons before any interface work depends on them.
- 03
Design notifications and audio
Adhan sounds, silent modes and reminder settings, tested on both platforms.
- 04
Add Qibla and location features
Compass, map fallback, mosque search and permission flows.
- 05
Test in the field, then release
Real-world testing across time zones and devices, then store submission.

Why Theme29 for a prayer app
It is already in Zabi
Customisable location-based prayer times, Qibla, nearby mosques and Ramadan times are part of a shipping product.
Platform-specific reliability
Notifications and background behaviour differ by OS and version, and we test for it.
Flexible starting point
Adapt Zabi, or build a prayer app around your community's timetable and brand.
FAQ
Frequently asked questions
Which calculation method should a prayer time app use?
There is no single answer, because communities follow different methods. A good app defaults to the method most common in the user's region and lets them change it, along with the Asr convention and manual adjustments.
Why do prayer times sometimes differ between apps and mosques?
Different calculation methods, angle conventions and rounding, or a mosque publishing its own fixed timetable. The mosque's own timetable is authoritative for that community, so our apps can display it.
Will the adhan play when the phone is locked?
It can, but the behaviour depends on the operating system and settings, especially battery optimisation on some Android devices. We build and test for this, and add guidance for users.
How accurate is the Qibla compass?
Accuracy depends on the phone's sensors and calibration. We add a calibration prompt and a map-based view as a fallback so users can verify the direction.
Can you add prayer times to an app I already have?
Yes. We can add prayer times, Qibla and reminders as a feature within an existing Flutter or native app.
