Built around the masjid, not around a calculation.

Any prayer app can work out when the sun sets. Saff reads what your masjid actually published, and counts down to the jamat you can still catch: first to the adhan, then to the iqamah, on your masjid's own clock, even when you travel.

Iqamah schedules come from the four platforms masjids publish on: Mohid, Masjidal, MasjidBox, and the WordPress prayer-times plugin. When they move Fajr, your phone knows before the announcement board does. New masjids appear for everyone the day they're added; the directory lives on a server, not inside the app.

Pin your masjid, or pin nothing and let Saff follow whichever of yours is closest as you move through the week. Anything missing can be added by pasting the masjid's website.
