About

Sajdah Pro

Features
Read full description

Sajdah Pro is a calm, modern companion for daily worship. We set out to build an app with all the functionality a Muslim needs day to day, and to keep it free, with no adverts, no subscriptions and nothing collected about you. PRAYER TIMES Accurate local times with a live countdown to the next prayer. Twelve calculation methods including Muslim World League, ISNA, Umm al-Qura, Karachi, Egyptian, Moonsighting Committee and Diyanet. Set your madhab for Asr, adjust any prayer by the minute, and keep separate jammah times for your masjid. Get a heads-up before each prayer and an alert at sunrise, or let a prayer ring as a full alarm, even on silent, so you wake for Fajr. THE QUR'AN All 114 surahs in the Madinah mushaf script, set with the care a printed page deserves: justified lines, verse seals in the margin, and juz, hizb and sajda marks in place. Four Arabic typefaces, adjustable size, and bookmarks for what you are memorising. Listen with three reciters, repeat an ayah as many times as you need, and download a surah to hear it offline. DHIKR 636 supplications across 35 collections: morning, evening, before sleep, after salah, travel, difficulty, and more. Each one carries its Arabic, transliteration, meaning and its source, so you can check what you are reciting. HIJRI CALENDAR The Islamic date alongside the Gregorian one, with the sacred days and events ahead. MOSQUE FINDER The nearest mosques on a map, with how far each one is and directions a tap away. Look near you, or anywhere you are travelling to. WIDGETS AND SIRI Put the next prayer, your streaks, the Hijri date or a full Qur'an player on your Home Screen and Lock Screen. Play and pause from Control Centre. Ask Siri when the next prayer is, or for today's times. A SKY THAT FOLLOWS THE DAY The background moves with the prayer times, from dawn at Fajr to a starlit night after Isha. Keep it automatic, choose one sky, or go plain, in light or dark. STREAKS Mark the day and watch the run grow. Time spent in the Qur'an and in dhikr marks itself. Skip a day deliberately without breaking your streak, because life happens, and a missed day is not a failure. TASBIH A counter that answers your thumb, with haptic feedback you can feel without looking, and custom targets. QIBLA A full-screen compass that shows the bearing to the Kaaba and tells you the moment you are aligned. ON YOUR WRIST An Apple Watch app with prayer times, the qibla, your streaks and a next-prayer complication. BUILT TO BE TRUSTED Prayer times, the qibla, the Qur'an and every dhikr work offline, and recitations can be downloaded so they do too. There is no account to create, no analytics, and no tracking of any kind. Your prayer times are worked out on your phone. Your location only leaves it when you open the mosque finder, which asks Apple Maps for mosques nearby. Free. No ads. No subscriptions.
