GLP-1 Tracker App: What to Look For and How to Use One Well

What a GLP-1 tracker app actually does

A GLP-1 tracker app is built around one job: keeping the moving parts of your medication routine in one place instead of scattered across a paper calendar, your Notes app, and memory. For people on Wegovy, Ozempic, Zepbound, Mounjaro, Saxenda, Rybelsus, or a compounded semaglutide or tirzepatide plan, that routine has more pieces than it first looks like — dose timing, injection site, how you felt afterward, whether you’re eating and drinking enough, and how your weight is trending over weeks, not days.

None of this is complicated on its own. The problem is remembering it three weeks later when you’re trying to explain to your prescriber why week six felt so different from week two.

Why tracking matters more on GLP-1 medications specifically

GLP-1 medications work in part by slowing gastric emptying and reducing appetite. That’s the intended effect, but it creates a side effect of its own: it becomes easy to under-eat, and specifically to under-eat protein, without noticing. Appetite suppression doesn’t come with a warning label that says “you’re not getting enough protein this week” — it just quietly happens.

That’s the main reason a purpose-built tracker earns its place over a generic notes app or calendar reminder. The things worth tracking on a GLP-1 routine cluster into a few categories:

• Dosing — which medication, what dose, and when it’s due next (weekly injections and daily oral doses have very different rhythms to keep straight)
• Injection site — where you last injected, so you can rotate and reduce irritation
• Side effects — nausea, constipation, fatigue, or other patterns, and whether they cluster around dose days or dose increases
• Nutrition basics — protein and water intake, which matter disproportionately once appetite drops
• Weight trend — not a single number, but the shape of the trend over weeks

What to look for in a GLP-1 tracker app

If you’re comparing apps, a few things are worth checking before you commit to one:

Does it cover your actual medication? Some apps are built narrowly around one brand name. Look for one that explicitly supports the medication you’re actually on — including compounded semaglutide or tirzepatide, which not every app acknowledges even though many people use it.

Does it fit your dosing schedule? Weekly injections and daily oral doses need different reminder cadences. A tracker that assumes everyone injects on Sundays won’t fit a daily Rybelsus routine.

Does it track more than just the shot? Side effects and nutrition are where the real day-to-day signal lives. A tracker that only logs “did you take your dose” misses the parts that actually help you and your prescriber understand how you’re doing.

Can you get your data out? Anything you log should be yours to export — CSV or JSON, not locked behind a paywall or trapped in a proprietary format you can’t open elsewhere.

What happens to your data? This is a genuinely sensitive category of health information. Worth checking whether the app sells data, runs ads, or ships with third-party analytics SDKs bundled in before you start logging.

How Pelora approaches this

Pelora was built around the idea that GLP-1 tracking should feel calm, not clinical or gamified. The core loop is simple: log your shot day and dose (with injection site), do a quick daily protein and water check-in, log side effects as they come up, and watch your weight trend over time. Everything you log stays local to your device — Pelora doesn’t run ads or bundle third-party analytics, and the only network activity is an optional, Premium-gated iCloud backup and RevenueCat for subscription status.

Core logging — shots, nutrition check-ins, side effects, weight, and full CSV/JSON export — is free, with no time limit. Pelora Premium is planned for advanced insights and report tools on top of that free foundation.

Pelora supports Wegovy®, Ozempic®, Zepbound®, Mounjaro®, Saxenda®, Rybelsus®, and compounded semaglutide or tirzepatide, on both weekly and daily schedules.

A note on what tracking can and can’t do

A tracker app is a record-keeping tool. It doesn’t diagnose anything, and it can’t tell you whether a side effect is expected or worth calling your prescriber about — that’s a conversation for your prescriber, not an app. What good tracking does is give that conversation better material to work with: a clear log instead of a foggy memory of “sometime in week four I felt off.”
