Notifications
A notification at each prayer time and an optional reminder a few minutes before.
Adhan wake-up alarm

Qibla
A compass corrected for magnetic declination, with the distance to the Kaaba.
Ramadan

Checked against the official tables

Wake up to the adhan, for the prayers you choose
Turn on only fajr, or fajr and maghrib, or all five. Each prayer has its own offset, from an hour before to an hour after.

A look inside
Dark by design, easy to read at fajr.

Read the privacy policyFrequently asked questions
Short answers to what people ask most.
Is Sidre free? Are there ads?
Sidre is free. There are no ads, no in-app purchases and no account.
Does it need the internet?
No. Prayer times are computed on your phone, and the city database comes with the app. Sidre works fully offline.
How accurate are the times?
Sidre was compared with Diyanet's official tables for 142 cities. In Türkiye every time is within one minute; abroad, 99.8% of times up to 62° latitude are within one minute. If your local mosque announces different times, you can adjust each time by minutes in Settings.
Which calculation methods are there?
Diyanet, Umm al-Qura, Muslim World League, ISNA, Egypt, Karachi, Tehran, Singapore, Dubai, Kuwait, Qatar and Morocco. Sidre suggests the method used in your country; you can change it in Settings, along with the Hanafi asr and the high-latitude rule.
Why does it ask for my location?
Only to find your city and compute the times and the qibla for where you are. It is optional: you can pick your city by hand. Your location never leaves your phone.
Can I set the alarm only for fajr, or for fajr and maghrib?
Yes. On the alarm screen, turn on any prayers you want: fajr, dhuhr, asr, maghrib, isha, and also sunrise, duha or tahajjud. Each has its own offset. If a notification would come at the same moment as an alarm, only the alarm rings.
