Glapp is a GLP-1 tracker built around shot phases, estimated medication levels, and a large public tool kit. Pep is a free GLP-1 tracker with the same daily logs plus a smaller set of dated calculators. If you are choosing between them, decide whether you want a science dashboard or a simple log you will keep using.
This guide compares Pep and Glapp on tracking, insights, calculators, platforms, and price. Facts below come from each app’s public site as of August 2026.
What Glapp does well
Glapp is strongest when you want the app to interpret the week for you.
- Shot phases so you can anticipate hunger, cravings, and side effects.
- Estimated rise, peak, and fade for semaglutide and tirzepatide.
- Vial inventory: remaining doses and expiration dates.
- Progress reports and an on-track check versus clinical-trial averages.
- iPhone, Android, and a web app. Their site also lists a Chrome dose-calculator extension.
- A public tools hub with many named calculators (units, clicks, cost per pound, protein, missed dose, and more).
Glapp says the native app is free to download. We are not listing a Glapp subscription price here because their marketing site does not publish one.
What Pep does well
Pep is built for the daily routine: log the dose, rotate the site, catch side effects, and see progress without extra interpretation. Rated 4.7 on both the App Store and Google Play from 2,700+ ratings. Free on iOS and Android.
- Shot and pill logging with reminders and injection site rotation.
- A body-level medication effectiveness indicator between doses.
- Weight, measurements, progress photos, and a daily summary.
- Protein, fiber, calories, and water in the same app.
- Side-effect logging you can take to a provider visit.
Pep’s web tools are fewer than Glapp’s, on purpose. Each one has a dated explainer next to it. The cost calculator uses August 2026 self-pay and list prices, not a cost-per-pound guess. The dose schedule, missed-dose, protein, and units calculators sit next to full guides on the resources library.
