English or Bahasa Indonesia. Takes effect immediately; dates and numbers still follow your device locale.

Location & Timezone

The place prayer times are calculated for. See Setting Your Location. The timezone follows your device.

Prayer Calculation Method & Madhab

The method sets the twilight angles behind Fajr and Isha — pick the one your local authority uses (KEMENAG, Muslim World League, Umm al-Qura, ISNA, and more). The madhab (Shafi or Hanafi) only shifts Asr. See Prayer Times.

Hijri Date

Nudge individual Hijri months by −2 to +2 days so the displayed date matches your local moon-sighting authority. A live preview shows today's date with and without your adjustments.

Backup

Settings → Backup & Restore:

• Export data — save all your tasks, tags, and recurring reminders to a file
• Import data — load a previous export, choosing Merge (add alongside current data) or Replace (delete current data first)
