Stop Guessing, Start Losing, See what's actually working. WeightSnap links your doses, weight, and daily habits to surface the patterns generic trackers miss.
Track your shot. See your patterns. The only tracker built for GLP-1 and peptide protocols that does the work for you.
Connect Apple Health and WeightSnap builds your picture automatically: weight, sleep, steps, calories, resting heart rate, workouts. Set your dosing schedule once and every dose is queued and ready, one tap to confirm.
No account, no sign-in, nothing to remember. Your data stays on your phone.
WeightSnap is built for the way GLP-1 and peptide users actually live, shot to shot. See exactly how your body responds across each dose cycle: when food noise peaks, when sleep dips, when energy returns. The more you track, the clearer your patterns become.
