The honest intermittent fasting timer. No ads. No account. No quiz to sit through before you can start. Your first fast begins in about ten seconds. KNOW WHAT YOUR BODY IS DOING Most timers just count. This one shows you where you are — blood sugar falling, the switch to stored fat, fat burning, ketosis approaching, deep fast. Each stage lights up as you reach it, with a plain note on what is happening inside you. A long fast stops feeling like waiting and starts feeling like progress. A RHYTHM THAT FITS YOUR LIFE Ease in gently with 14:10. Settle into the classic 16:8. Eat with your body clock on 13:11. Go further with 18:6 or 20:4 when you are ready. Change your mind whenever you like. IT FORGIVES YOU Real life interrupts fasts, and most apps punish you for it. Forgot to stop the timer? This one notices and asks when you actually broke your fast, instead of quietly saving a wrong one. Ended a fast by accident? Undo it. Never started the timer at all? Add the fast afterwards. Your streak and your history stay true to what you really did. PROOF THAT YOU ARE STICKING WITH IT Your current and longest streak, your week at a glance against your goal, and every fast you have logged. What keeps most people going is a run they do not want to break. ANSWERS WHEN YOU WANT THEM What happens hour by hour while you fast. Which protocol suits you. Whether coffee breaks a fast, how to break one properly, and who should not fast at all. NO TRICKS No ads — least of all food ads while you are fasting. No account and no email. Your fasts stay on your phone. Clear pricing, a close button you can actually find, and a restore that works. A NOTE ON HEALTH This is a timer and a tracker, not medical advice. Fasting does not suit everyone — talk to your doctor before changing how you eat, especially if you are pregnant or breastfeeding, have a history of eating disorders, or take medication affected by meal timing.
