All the app comparisons, in one place

We wrote these because people ask, and because the answer is not always "use ours." Every comparison is built from the other app's public store listing and site as of October 2026, says plainly when a feature is not listed rather than claiming it is missing, and ends with who each app is right for.

The comparisons

• Peptide AI vs MeAgain. The whole-routine GLP-1 diary with protein, fibre and progress photos.
• Peptide AI vs GlucoPal. Free, no account, with the injection-site rotation map.
• Peptide AI vs Glapp. The weekly report and the estimated medication level chart.
• Peptide AI vs Pep AI. The closest in scope: peptides and GLP-1s, body map, side effects with severity.
• Peptide AI vs Glowise. Photo food logging and a half-life visualisation.
• Peptide AI vs MyFitnessPal. The calorie tracker most people already have, and what it cannot do for a weekly shot.

How we score them

Four questions, the same on every page.

1. What does it log? Dose, site, side effects, food, weight, labs, wearables. Listed means listed in the store description. Not listed means we could not find it, not that it is absent.
2. What is free? A free tier that logs is different from a free download that paywalls the log.
3. What does it read back? Charts, reports, estimated drug levels, an AI that answers from the data. This is where apps separate.
4. Who is it for? One drug or a stack. Food-first or dose-first. Casual or clinical.

Where Peptide AI is not the pick

If you want an app with no account and no sync, GlucoPal. If you only want a weekly chart of one drug, Glapp. If the food photo is the feature you will actually use every day, Glowise. We are the pick when the log needs to hold more than one compound, when bloodwork belongs on the same timeline, or when you want the writing to be free and the reading to be the thing you pay for.
