You fast, the timer does the counting

Pick a preset, tap Start fast and let Jam Puasa count down the rest. Intermittent fasting or Ramadan fasting, it handles both.

Overview

No more doing sums in your head while your stomach growls. Pick a preset, or set your own with Custom, and start. The timer shows the time left and which fasting zone you're in.

For the fasting month there's a Ramadan and sunnah mode. Imsak to maghrib is worked out offline for the city you choose, as a Kemenag-style estimate. Every session goes into an unlimited history, and you can get a notification when your fast or eating window ends.
