Shotsy is a mobile app for people on GLP-1 medications. It keeps your injections or daily pills, dose schedule, injection sites, side effects, weight, and basic nutrition (calories, protein, water) in one place. It's built around how GLP-1 treatment actually runs: weekly shots, titration in steps, and side effects that tend to cluster around dose changes.
The core app is free. An optional paid subscription, Shotsy+, adds the estimated medication level chart and automatic health-data sync (details below; as of September 2026).
Supported medications
Shotsy tracks semaglutide (Ozempic, Wegovy, and oral semaglutide: Rybelsus and the Wegovy pill), tirzepatide (Mounjaro, Zepbound), liraglutide (Saxenda, Victoza), dulaglutide (Trulicity), and retatrutide. Retatrutide is still investigational and not an approved medication, so that option is for trial participants. You can log more than one medication, each with its own schedule. This list comes from the app's store listing as of September 2026; check the app for the current set.
What it does
Free features:
- One-tap dose logging for injections or daily pills, which builds a full medication history over time
- Injection site rotation tracking, a useful companion to the technique advice in our guide on injection site reactions
- A weekly or daily schedule with countdowns and reminders, so a dose doesn't slip by (see what to do if you miss a GLP-1 dose)
- Side effect logging, so you have a record of which symptoms showed up when; compare it with the typical pattern in our GLP-1 side effect timeline
- Weight, calorie, protein, and water tracking
- Analytics and trend charts across weight, side effects, and nutrition
With Shotsy+:
- Medication level charts, which estimate how a drug's concentration rises and falls between doses based on published pharmacokinetic data. It's a visual way to understand half-life.
- Apple Health sync on iPhone (Health Connect on Android), which pulls in weight, calories, protein, and water automatically instead of making you enter them by hand
Why it helps during GLP-1 treatment
Titration is easier to follow when dose history and symptom logs sit side by side. Side effects and dose changes are closely linked (see how titration schedules work), so you can check whether a symptom flare reliably follows a dose increase or shows up at random.
A logged history also guards against dosing mistakes like the ones in our guides on missed doses and accidental double dosing.
It gives you something concrete to bring to appointments. A record of doses, side effects, and weight trends beats trying to recall the last several weeks from memory, especially if you're talking to your doctor about side effects that aren't improving.
And it pairs well with nutrition tools. Used with a detailed food tracker like Cronometer and a baseline estimate from the TDEE Calculator, Shotsy's medication and weight data helps connect dose, symptoms, intake, and results.
