About this app

Nidaa is a calm, focused prayer-times app for individuals and groups.
It does one thing well: it tells you when to pray and calls you to prayer — with the adhan sounding at the right time, even when the app is closed and your phone is locked.

PRAYER ALARMS THAT ACTUALLY FIRE
Nidaa is a prayer-alarm app. It uses exact alarms so Fajr, Dhuhr, Asr, Maghrib, and Isha sound on time, reliably, without you needing to keep the app open. Set an optional wudu reminder before each prayer, choose the adhan or a gentle notification, and mute everything with one tap when you need silence.

MAKE IT YOURS
Nidaa is built to fit the way you pray. Adjust any prayer time to match your local mosque exactly. Choose your Asr calculation (Shafi or Hanafi). Turn the adhan or wudu reminder on or off for each individual prayer. Switch between light and dark themes, and use the app in English, Norwegian, or Arabic. Every detail bends to your needs — nothing is locked.
SHARE ONE SCHEDULE WITH YOUR GROUP
One person can import a monthly timetable, and everyone in the room stays in sync automatically — the whole group sees the same prayer times. Perfect for a family, a school, an organisation, a mosque community, or an event. No accounts, no sign-ups — just a simple room code to share. Prefer to use it alone? Nidaa works beautifully solo too.

ACCURATE TIMES, EVEN AT HIGH LATITUDES
Nidaa calculates prayer times using the Muslim World League method, with proper handling for high-latitude locations where the sun barely sets in summer.

CALM BY DESIGN
No ads. No accounts. No clutter. No tracking of who you are. Just prayer times, presented simply and beautifully — with full right-to-left support in Arabic.

A SPACE TO GIVE
Nidaa quietly features the volunteer organisation Jiyan, so you can learn about their relief work and support them directly if you wish. Nidaa never handles the money — giving goes straight to Jiyan.
Nidaa collects no personal information. It's a quiet, respectful companion for your daily prayers.
