WeightSnap: Peptide Tracker

Track your shot. See your patterns. Get the verdict. 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. Prefer to skip all that? Three taps a day (ate, moved, dose feel) power the same analytics, no Apple Health and no calorie counting required. 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.

THE VERDICT
The Doses tab opens with the answer: Building, Working, Steady, or Worth watching
Every word backed by your own numbers: "Down 6.2 lbs over the last 28 days. Dose held strong 4 of 4 cycles."
Receipts, not dashboards

YOUR WHOLE PROTOCOL, ONE CARD
Track retatrutide, tirzepatide, semaglutide, and any peptide, each with its schedule, cycle, and color
Popular blends built in: log KLOW, GLOW, Wolverine and more as a single injection
Vial inventory: doses left in the open vial, sealed vials on hand, supply dates
Injection site rotation with abdomen quadrants, dose reminders, titration history

RECONSTITUTION CALCULATOR

STALL CHECK
Trend flat for 3 weeks? Stall Check shows what else changed in the same window
Movement, eating, sleep, time on dose, even your Earn It record, all counted against your usual
No advice, just what changed. A pattern you can bring to your prescriber

WEAR-OFF DETECTION (BETA)
Your "fading" days mapped against your dose cycle
"Food noise climbs from 2.5 to 5.2 in the last two days before your shot. Rose in 11 of 11 cycles."
