    The best GLP-1 tracker apps in 2026, by what you need

    Short answer

    The best GLP-1 tracker depends on what you need. For a simple free shot log, Shotsy or GlucoPal. For nutrition-first tracking, MeAgain or Glowise. For level charts in a browser, Glapp. For GLP-1s plus peptides, vials and food in one app, Pep AI (our app, subscription required). This page compares all of them from their own listings.

    We make Pep AI, so we are not neutral, and this page does not pretend to rank the field. Instead it groups the main GLP-1 trackers by what they are best at, using only what each company says about its own app on its website and store listings, checked on September 28, 2026. Where an app is a better fit than ours, we say so.

    What to look for in a GLP-1 tracker

    Most of these apps log a shot and remind you when the next one is due. The differences show up in everything around the shot, and it is worth deciding which of these you actually need before you choose.

    Do you need a medication level chart?

    Several apps chart an estimated level from your doses and published half-lives. It is a model, not a blood test, but it helps explain why appetite or side effects shift across the week. Some apps include it free (Glapp says its level curve is free); others put it in a paid tier (Shotsy+, GlucoPal Pro).

    How much food tracking do you want?

    Protein, fiber and water are the nutrients most likely to fall short when appetite drops. If food logging matters, check how each app logs meals (photo, barcode, search, voice) and which methods sit behind a paywall. Glowise and MeAgain lean hardest into nutrition; MyFitnessPal has the largest database; Pep AI logs by photo, barcode, restaurant menu scan or search.

    Do you mix your own vials or take other peptides?

    Most GLP-1 trackers assume a prefilled pen. If you draw from a vial, reconstitution math and per-vial tracking matter, and if you take peptides beyond a GLP-1, you need an app that supports them. Pep AI and PeptidePal are built for this; Glapp includes dose calculators and vial inventory for GLP-1s.

    Which platform are you on?

    GlucoPal is iPhone only for now. Glapp also works in a web browser. The rest, including Pep AI, run on both iPhone and Android.

    Do you want to pay?

    Shotsy, MeAgain, GlucoPal and Glapp all describe free tiers that cover core logging. Pep AI requires a subscription for tracking. If you want to start without paying, one of the free tiers is the honest recommendation.

    Best for each need

    One line per app, based on what each company emphasizes about itself.

    • Pep AI: people who track GLP-1s and peptides, mix vials, and want food, side effects, levels and weight on one timeline.
    • Shotsy: a straightforward, mostly free GLP-1 shot log with site rotation, side effects and weight.
    • MeAgain: GLP-1 users focused on food and protein, with an AI companion and a free version.
    • GlucoPal: iPhone users who want free dose, food and weight tracking without an account.
    • Glapp: semaglutide and tirzepatide users who want free level charts and supply tracking, including on the web.
    • Glowise: people who want meal plans and recipes built around a GLP-1.
    • PeptidePal (Blank Labs): peptide protocol users who want reconstitution math and a community.
    • MyFitnessPal: people whose priority is calorie counting against a very large food database.

    Key takeaways

    • There is no single best GLP-1 tracker; the right one depends on food, vials, peptides, platform and price.
    • Several apps offer free tiers for core logging; Pep AI requires a subscription.
    • Pep AI's case is breadth: GLP-1s and peptides, vials, food, side effects and weight on one timeline.
    • Whatever you choose, a consistent log is more useful to your prescriber than memory.

    If breadth is what you need.

    Doses, vials, injection sites, food, side effects and weight on one timeline, for GLP-1s and peptides alike. Download Pep AI on iPhone or Android.
