tr8ck logs your fasting window and connects it to sleep, mood, weight and energy — in your numbers, not the average podcast guest.
Zero gave you a timer. The podcasts gave you a religion.
Nobody told you if your body is actually responding.
Stop the timer. Start the answer.
16:8, 18:6, OMAD, your own. tr8ck handles them all. Voice-log your last meal — done.

Sleep, mood, training, weight. tr8ck sees how your fast lands — not just whether you finished it.

"On 16:8 days you sleep 22 minutes more." Or you do not. tr8ck tells you the truth.

Forget the streak. Is it actually moving your body?

Voice-log your last meal. tr8ck handles the timer in the background. No fiddly buttons.

Late-night meals are the #1 sleep killer tr8ck detects. The Fasting module shows you yours, by name.

Some people thrive on a long fast. Some go to pieces by 11am. tr8ck shows you which one is you.

tr8ck filters out the daily scale noise and shows you the actual response across your fasting protocol.

Combining IF with GLP-1? tr8ck handles both. See whether the fast is adding anything on top of the medication.

tr8ck does not run guilt loops. Miss a day, log it, move on. The pattern beats the streak.
If you wanted a doctor's report, you would have gone to a doctor. You came here to feel better.
