Store description excerpt
One giant button. That is the whole app. Tap it to start a fast, tap it to end. A real 24-hour clock face shows exactly where your fast sits in the day, not an abstract bar. Available in English, Spanish, French, Arabic, Russian, Hindi and Ukrainian. RAMADAN Switch on Ramadan mode and the timer stops being a number of hours you picked. Your fast runs from suhoor to iftar, worked out on the phone for wherever you are, and both times move a few minutes every day exactly as they really do. Six calculation methods: Umm al-Qura, Dubai, the Egyptian General Authority, the Muslim World League, Karachi and North America. The one used where you are is chosen for you. Everything is computed on the device from your location, so it works with no signal at all and nothing is sent anywhere. Ramadan mode appears in the app as the month comes round. WHY FASTONCE Nearly every fasting app rents you a timer. You answer a quiz, hand over an email, then pay monthly for a clock. FastOnce asks for none of that. No account, no sign-up, and it opens straight onto the button. WHAT YOU GET, FREE A dial that actually reads as time The ring wraps a 24-hour wall clock, so you can see at a glance that your fast ends at 8pm rather than decoding a percentage. Plans that fit your day 12:12, 14:10, 16:8, 18:6, 20:4 and OMAD, or set your own hours. You can also pick the time you want to finish and the length is worked out for you. It keeps going by itself When your fast ends the eating window opens, and when that closes the next fast begins. Weeks can pass without opening the app. Forgot to hit start Backdate the start time and the ring, the stages and every reminder recalculate instantly. Stages, explained in plain language Blood sugar drop, fat burning, ketosis and autophagy, each with a short friendly explanation. No clinical claims, no scare tactics. Your calendar, your streaks, your totals A month calendar of completed fasts, current and longest streaks, and your totals. Free, and staying free. Gentle nudges, only if you want them Optional pings at the halfway mark, at each stage, when your fast completes, and short encouragement while you are in it. Quiet overnight. A home-screen widget Your current fast at a glance without opening anything. FASTONCE PRO, ONE PAYMENT Pro is a single purchase. No subscription, nothing renews. It adds three things and nothing else: Charts and trends Hours per day, how often you reach your goal, your weekly average, and the hour you actually start. Export your log Every fast you have finished, as a spreadsheet file that leaves the app and is yours to keep. Still no account, still offline Pro changes what you can see, not where it lives. PRIVACY No account, no analytics, no advertising, no server of ours. Nothing you record ever leaves your iPhone, and neither does your location. The only time FastOnce talks to anything is when you buy Pro, which goes through the App Store. FastOnce shares general wellbeing information, n
