JustFast - Timer

Fasting is a beautifully simple intermittent-fasting timer that does one thing well: it tracks your fast.

No goals to hit. No streaks to protect. No accounts, no ads, no clutter. Just tap once to begin, and a calm live timer counts your fast while a glowing ring fills toward the next stage your body moves through.

WHY IT'S DIFFERENT
Most fasting apps pile on dashboards, reminders, and pressure. This one strips fasting back to its essence — a clear timer you can glance at and put away. It's designed to feel quiet and focused, not gamified.

WHAT YOU GET
• One-tap start and stop, with a big, satisfying button
• A live timer that keeps perfect time across restarts, time-zone changes, and daylight saving
• Metabolic milestones — the ring fills toward the next stage (blood sugar settling, glycogen burning, fat burning, ketosis, autophagy, and more)
• Tap any milestone for an honest, plain-language explanation of what's happening in your body
• Forgot to start the timer? Just tap the ring to fix your start time. Forgot to stop? End your fast at the right time after the fact.
• An ongoing notification shows your current duration at a glance
• A simple history of past fasts — swipe to delete
• 18 languages and a clean dark design

HONEST BY DESIGN
The milestone descriptions are written plainly and honestly. Where the science is still early or based mostly on animal research, we say so. This app is a timer and an educational companion — not medical advice.

PRIVATE BY DEFAULT
Your data stays on your device. There are no accounts, no sign-ups, no tracking, and nothing is uploaded.

Fasting works for 16:8, OMAD, alternate-day, extended fasts, or any schedule you like — because it never forces a schedule on you.

Note: Fasting is not a medical device and does not provide medical advice. Talk to a healthcare professional before starting any fasting regimen, especially if you are pregnant, nursing, taking medication, or have a medical condition.
