PeptideMate vs Shotsy
Shotsy is one of the most widely used GLP-1 trackers, with more than 34,000 App Store ratings, and its website says its core features are free. Choose it for weekly GLP-1 shots with weight, food and medication-level charts. Choose PeptideMate if you also track peptides from vials, want vial records with lot numbers and expiry, or need a web app.
Disclosure: PeptideMate is ours. Details of Shotsy come from its public App Store and Google Play listings, checked on 29 October 2026, and from its own website where marked. We have not tested Shotsy.
Choose Shotsy if…
- You take a GLP-1 medicine and want weight, calories, protein and water in the same app.

- You want Apple Health or Health Connect to fill in weight and nutrition for you.
- You want an app with a long track record and a very large number of reviews.
- You want the app in a language other than English; its App Store listing has 17.
Choose PeptideMate if…
- You track peptides from vials as well as, or instead of, a GLP-1 pen.
- You want each vial on record: lot number, cost, sealed or reconstituted, expiry, storage and amount left.
- You want to log from a browser on a computer.
- You want CSV rather than PDF, so you can open your history in a spreadsheet.
- You would rather not have food tracking or level estimates in your log.

Privacy and where your data goes
Shotsy's App Store label lists no data used to track you and no data linked to you; health and fitness, user content, usage data and diagnostics may be collected without being linked to your identity. Its website says your data is kept on your device and in your iCloud on iPhone, and in Google Firebase on Android. Its Google Play data safety section says it may share some data types with third parties and that data is encrypted in transit.
PeptideMate's App Store label says "Data Not Collected", and its Google Play data safety section says no data is collected or shared. The optional web app stores your entries with your account on our server.
Store privacy labels are the developer's own description and are not verified by Apple or Google. Read each app's privacy policy for the detail.
Shotsy, MeAgain or PeptideMate?
People comparing Shotsy often look at MeAgain too. MeAgain has even more App Store ratings (over 39,000) and puts food logging by photo and barcode at the centre, while Shotsy's listing leads with dose tracking, schedules and medication-level charts. Both are GLP-1 apps first.
If a weekly GLP-1 shot is all you track, either is a reasonable place to start; the full list is in our roundup of GLP-1 tracker apps. PeptideMate fits better when vials, several peptides or a browser are part of the picture.
Does either app tell you what to take?
Check Shotsy's own disclaimer on its listing. PeptideMate records what you enter and does unit arithmetic on it; it never suggests a peptide, an amount or a schedule. Decisions about what to take belong with your prescriber or pharmacist. See the medical disclaimer.
