🔒 Private by design: no accounts, no tracking, every calculation runs on your device.

Astronomical calculations are an aid — the official start of the month is decided by the authority in your country.

Recent changes:
Stability fixes: the Sky Map camera now starts reliably after granting permissions and when leaving and returning quickly, and crescent calculations work for any date, even outside the Umm al-Qura calendar range (before 1937 or after 2077).
