Peptide & GLP‑1 tracker comparison

Shotsy and Pep AI are good apps — this is an honest look at where each tool fits, as of July 2026. The short version: choose Shotsy for a polished GLP‑1‑only iPhone experience, Pep AI for a peptide-focused iOS app, and Peptilot if you want peptides and GLP‑1s in a browser on any device — a full web app with one synced account, no install. Native Peptilot apps are in development.

Looking for a Shotsy alternative on Android or the web?

Shotsy earned its reputation: it's a polished GLP‑1 tracker with medication-level charts and a generous free tier. Where it stops is scope and surface — it's built around GLP‑1 medications, and your data lives on-device with iCloud backup. If you track compounds beyond GLP‑1s, want to log from a browser, or want one account you can open on an Android phone and the desktop alike, that's exactly the gap Peptilot was built for.

Considering a Pep AI alternative?

Pep AI covers the peptide side well, with a large compound library and an AI assistant. Peptilot's differences are structural: a real backend account instead of iCloud (so the web app is first-class and your history survives device switches), EU hosting with a GDPR-first privacy posture and no third-party analytics, CSV export of your whole history so your data can leave whenever you want, and fully custom compounds with your own units and half-lives.

What Peptilot doesn't do

Fairness cuts both ways: Peptilot has no sourcing or vendor features by design (and never will), it has no native iPhone or Android app yet (those are in development; today Peptilot is the web app), it exports your history but cannot import an old app's history for you, and unlike Shotsy there is no permanently free tier — Peptilot is a subscription with a 3-day trial, so if you want to track for free indefinitely, or want an entirely offline, no-account tracker, a local-first app like Shotsy may suit you better. Try the web app in two minutes and decide with your own data — the calculator doesn't even need an account.
