The 7 Best GLP-1 Tracker Apps, Compared

MeAgain has the broadest reach of any dedicated GLP-1 tracker, and it earns it. Coverage is genuinely comprehensive — shots with site rotation and estimated medication level charts, food by photo or barcode or voice, side effects, weight, and progress photos with a ghost overlay for pose matching. If your priority is a large, active community and an app that a lot of people have stress-tested, this is the safe pick.

Its real edge is motivation design. The companion widget, streaks, and journey cards do something most trackers do not attempt: they make a Tuesday with no visible progress still feel like a day you showed up. That matters more than feature checklists over a twelve-month course.

Where it falls short is after the logging. There is no web portal and no report generation — your data stays inside the app. For a medication most people take under a prescriber's supervision, having nothing to hand a doctor is a real gap.

Shotsy is the most rated app in this ranking and the most rigorous about the medication itself. Its estimated medication level charts, built from published pharmacokinetic data, show you where you are in the absorption and clearance curve — which is genuinely useful for understanding why day two feels different from day six.

It handles the surrounding data well too: weight, calories, protein, water, Apple Health sync, and a detailed side effect list that users repeatedly single out in reviews as the thing they bring to appointments. Privacy is a design principle rather than a footnote, with device-based storage.

The trade-off is scope. Food logging exists but is thin next to Dose AI, MeAgain, or Pep, and there is no meaningful guidance layer. Shotsy tells you precisely what happened to your medication; it is much quieter on what to do about it.

Glapp does one thing better than anyone: it puts your results in context. Weekly charts show your weight change on each specific dose, then compare it against clinical trial data and anonymized results from other users. When you are three weeks into 5mg and wondering whether your loss is normal, that answer is hard to find anywhere else.

Its supply management is also unusually practical — tracking vials, pens, remaining volume, and expiration dates. If you are managing compounded medication or juggling pharmacy timing, that is a real workflow other apps ignore entirely.

The daily check-in covers side effects, mood, sleep, and hunger, which gives it the second-strongest symptom picture in this ranking. Food logging is the weak link, and the widest platform coverage here comes with a rating count that reflects how new the app is.

Pep is the app for people who find most trackers exhausting. It covers the essentials properly — injections or oral pills, custom reminders, protein and fiber and water, weight and measurements and progress photos, an AI food scanner, and Apple Health sync — and then stops. Reviewers consistently praise how neatly the main screen is put together, and that restraint is the product.

It is one of the few apps here that treats oral GLP-1s as a first-class case rather than an afterthought, which matters more every quarter as pill formulations expand.

What you give up is depth. Symptom tracking is present but shallow, there is no correlation analysis, and no web access. Pep will not surprise you with an insight — it will just reliably hold your routine.

Phaze is the most ambitious app in this ranking relative to its size. It ships a genuinely offline Apple Watch companion, a customizable dashboard of draggable tiles, voice-activated meal logging, ghost-overlay progress photos, a pharmacokinetic dose cycle ring, and a 0–1,000 lifestyle score that turns a fuzzy week into a single number worth beating.

It also has an AI diet assistant and medical report generation — the only app besides Dose AI to attempt both. Accessibility support is the best here, covering VoiceOver, voice control, enlarged text, and reduced motion.

The problem is evidence. With 38 ratings, there is almost no independent signal about whether any of this holds up over months of real use. The feature list reads like a top-three app; the track record does not exist yet.

Gala is the only app here that is really a front end for a medication service. It logs shots, doses, side effects, weight, and calories, and produces dosage charts — but its distinguishing features are connecting you to Gala's own medical team and tracking your medication orders and shipments. If you are already a Gala patient, that integration is genuinely convenient.

If you are not, the case is much harder to make. At 3.7★ across 917 ratings it has the lowest score of any app in this ranking by a wide margin, and reviews cluster around specific friction — food entries that cannot be renamed, interface complaints, and at least one publicly detailed dispute over a $550 refund.

We have included it because a credible ranking should not quietly omit the weakest option. Notably, the competing roundup published by MeAgain leaves Gala out entirely.
