WeightSnap vs Shotsy: Which GLP-1 Tracker Is Right for You?

Last updated: July 2026

Shotsy is the most popular GLP-1 tracker, with roughly 25,000 App Store ratings and a polished logging experience. WeightSnap logs the same things Shotsy does, then goes a step further: it reads your data and answers the question logging never does. A verdict card tells you whether the medication is working. Stall Check explains flat stretches. Wear-Off Detection flags fade patterns before your next dose. It is the difference between keeping records and getting answers from them.

Quick answer

Choose Shotsy if you want the most popular option, you are on Android, or built-in food logging matters to you. Choose WeightSnap if you want to know whether the medication is actually working: a plain-language verdict, stall analysis, wear-off detection, and cycle-by-cycle recaps, all built from your own numbers. Medication-level charts and Apple Health sync are premium features on Shotsy; WeightSnap includes both in every plan.

Logging tells you what you did. WeightSnap tells you what it means.

The verdict card: one answer, backed by your own numbers.

Every tracker shows you a weight chart and a dose log. WeightSnap sits a layer above them. The verdict card at the top of the Doses tab reads Building, Working, Steady, or Worth watching, and each state comes with receipts: your trend over the current dose, how many cycles the dose has held strong, what changed since your last adjustment.

When your trend goes genuinely flat for weeks, Stall Check appears and shows what moved during the flat stretch and what held steady: eating, movement, sleep, how the dose felt. When your check-ins show a repeating late-cycle fade, Wear-Off Detection surfaces the pattern. And every completed dose cycle gets a recap comparing it to the one before. No other GLP-1 tracker does any of these.

One more difference in kind: Shotsy is built around GLP-1s. You can add other medications as custom entries, but there are no protocols, vial inventory, or reconstitution math behind them, and level curves exist only for GLP-1s. WeightSnap treats the rest of your stack as first class: 30+ peptides and blends plus custom compounds, each with per-compound schedules, vial inventory, and a reconstitution calculator for anything that arrives as a powder.

Why WeightSnap wins

It answers the only question that matters. The verdict, Stall Check, Wear-Off Detection, and cycle recaps interpret your data instead of just charting it. Shotsy has no equivalent for any of the four.

The charts Shotsy paywalls are included. Medication-level curves and Apple Health sync are premium on Shotsy. WeightSnap ships both in the trial and every plan.

Tracking without the homework. By-feel mode is three taps a day, with no food logging and no wearable required. Switch between by-feel and full detail whenever you like.

It handles the rest of your stack. 30+ peptides and blends, custom compounds, vial inventory, reconstitution math. Shotsy's custom entries carry none of that tooling.

A lifetime exit. $79.99 once, an option Shotsy does not offer, and WeightSnap's $39.99 yearly matches Shotsy's lowest listed annual tier.

Where Shotsy is strong

It is the most popular GLP-1 tracker, with a large community and about 25,000 ratings. If you want the option most people use, that counts for something real.

Built-in food logging. Calories, protein, and water live inside Shotsy. WeightSnap imports nutrition from Apple Health but does not log food itself.

A permanent free tier. Shotsy's core logging is free forever. WeightSnap is a one week free trial, then paid.

Android. WeightSnap is iOS only today.

You are on Android, you want built-in food logging, or you want the most popular app and its community. Its free tier covers basic logging with no time limit.
