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. MADE FOR IPHONE DUO Half-open on a table, the ring faces you above the hinge with the controls at your thumb. Fully open, the timer becomes two pages — your progress on one, your stage and controls on the other. The fast keeps running as you fold, unfold and rotate. 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.

Some days you answer in four minutes. Other days the same message sits open until evening. It looks like mood. Mood is not that regular. Astersong starts from a different idea: you are not one steady person with a mood on top. You have sides, and they take turns leading your day. The app names seven of them, guesses which one today will call on, and lets you check that guess against the day you actually had. YOUR TEAM OF SEVEN Seven sides, each with a name and a character. The one who decides and goes first. The one who takes care of people. The one who needs the sentence to be right before sending. The one who holds the line. You meet yours in the first minute, worked out from the moment you were born. A GUESS EVERY MORNING One short note about what today may ask of you and which side may take the lead. Something to hold against the day, never a prediction. THIRTY SECONDS IN THE EVENING Rate your mood and energy, tap what the day touched, add one line if you feel like it. Then you say what the day actually asked of you, and you find out whether the morning had it right. YOUR SIDES TALK IT OVER After the check-in, your sides discuss the day between themselves, each in their own voice, about your real day and nothing else. THE PATTERN, AFTER A WEEK Seven evenings in, the journal starts showing what your days keep asking of you, which kinds of days drain you, and how often the morning guess was right. Not a score. Your own record. TALK TO ANY OF THEM Ask one side why it pushed so hard today. Or ask about the whole of you at once. WHAT THIS IS NOT Astersong is a tool for self reflection. It is not therapy, not a diagnosis, and not advice from a professional. The words your sides say are written by AI, so treat them as something to think with, not as a verdict. AI features stay off until you turn them on, and you can turn them off again at any time in Settings.
