- Four GLP-1 tracking apps offer free core features in 2026: MyWhy, Shotsy, Glippy, and Glapp
- Drug-level visualization — one of the most useful GLP-1 features — is paywalled by Shotsy but free on MyWhy and Glapp
- Only MyWhy combines GLP-1 treatment tracking with behavioral meal check-ins and daily reflections in a single free app
- Most general weight-loss apps (MyFitnessPal, Noom, Lose It) do not offer GLP-1 injection tracking at all
- Medical GLP-1 programs (Calibrate, WeightWatchers Clinic) start at $25-199/month and focus on prescriptions, not tracking
Why you need a GLP-1 companion app
If you're on Ozempic, Wegovy, Mounjaro, or any other GLP-1 medication, you already know the drill: weekly injections, dose titrations, side effects that come and go, and weight that (hopefully) trends down over time. A GLP-1 tracking app helps you see the full picture — when your next injection is due, where you are in your treatment cycle, and how your weight and habits are changing alongside your medication.
The problem? Many GLP-1 tracker apps put their best features behind a paywall. Drug-level visualization, detailed treatment analytics, and injection history exports often require a monthly subscription ranging from $5 to $40. For people already paying for expensive medication, that adds up.
We looked at every dedicated GLP-1 tracking app available on iOS and Android in 2026 and compared what you actually get for free.

App-by-app breakdown
MyWhy
MyWhy takes a different approach than other GLP-1 trackers. Instead of focusing purely on injection logging, it combines treatment tracking with behavioral meal check-ins, weight progress, and daily reflections — all in one app, all free. The philosophy: medication reduces hunger, but it doesn't automatically change habits. MyWhy helps with the behavioral side.
The meal check-in system skips calorie counting entirely. You snap a photo, mark the meal as supportive or unsupportive of your goals, and move on. It takes about 30 seconds. Over a week, a visual chart shows your pattern. The GLP-1 treatment tracker includes injection cycle status, next dose dates, and drug-level visualization based on published half-life data — features that other apps charge $5-8/month for.
Strengths
- Drug-level visualization included free
- Behavioral meal tracking (no calorie counting)
- Daily reflections and personal "Why" motivation system
- iOS and Android
- All core features free, no ads
Limitations
- No built-in community
- Newer app with smaller user base
Shotsy
Shotsy is the most popular dedicated GLP-1 tracker on the market. The free tier covers the basics well: dose logging, side effect tracking, weight charts, and basic nutrition logging. It's focused and straightforward — you open the app, log your injection, and you're done.
Where Shotsy gets you is with premium features. Estimated medication level visualization — the chart that shows where your drug levels are between injections — requires a paid subscription at $7.99/month or $39.99/year. Advanced treatment analytics and some reporting features are also premium-only.
Strengths
- Largest user base among GLP-1 trackers
- Clean, simple interface
- Side effect tracking included free
- iOS and Android
Limitations
- Drug-level visualization paywalled ($7.99/mo)
- Advanced analytics require premium
- No meal tracking or behavioral features
- No reflection or motivation tools
Glippy
Glippy stands out as a fully free, no-paywall GLP-1 tracker. It doesn't lock any features behind a subscription — instead, it supports itself through in-app advertising. The most unique feature is a built-in community where users can ask questions, share progress, and find accountability partners.
The trade-off is availability: Glippy is currently iOS-only, so Android users are out of luck. It also focuses narrowly on injection and side effect tracking without meal logging or behavioral tools.
Strengths
- Everything is free, no paywall ever
- Built-in community and accountability features
- Side effect tracking
- Charts and data never locked
Limitations
- iOS only — no Android support
- Ad-supported (ads in community feed)
- No drug-level visualization
- No meal tracking or behavioral tools
Glapp
Glapp is built by GLP-1 users and health-tech professionals, and it's completely free with no premium paywall. It covers the core tracking needs well: injection logging, treatment cycle views, and drug-level visualization. Like Glippy, it doesn't charge for any features.
Glapp is a solid choice if you want straightforward GLP-1 tracking without any upsells. It lacks the behavioral and meal tracking features that some users want, but for pure injection tracking, it delivers everything free.
Strengths
- Drug-level visualization included free
- No paywall, no premium tier
- Built by GLP-1 users
- iOS and Android
Limitations
- No meal tracking
- No behavioral or reflection tools
- Smaller user community
What about general weight-loss apps?
If you're considering a general weight-loss app alongside your GLP-1 tracker, here's the reality: most of them don't offer injection tracking at all.
- MyFitnessPal ($0-24.99/mo) — No GLP-1 tracking. Focused entirely on calorie counting and macro tracking. The barcode scanner, once free, now requires a $19.99/month Premium subscription.
- Noom ($17-70/mo) — No GLP-1 tracking in the standard plan. Noom Med offers GLP-1 prescription support starting at $199/month, but that's a medical program, not a tracker.
- Lose It! ($0-9.99/mo) — No GLP-1 tracking. Calorie counting with a 47-million food database. Barcode scanning was recently moved behind the Premium paywall.
If GLP-1 treatment tracking matters to you, a dedicated GLP-1 companion app is the way to go. General weight-loss apps were designed for calorie counting, not medication management.
What about medical GLP-1 programs?
Programs like Calibrate ($199/month) and WeightWatchers Clinic ($25-149/month) offer a completely different thing: they prescribe and manage your GLP-1 medication, with coaching and support built in. They're medical programs, not tracking apps.
If you already have a prescription from your doctor and just need to track your treatment, you don't need a $200/month program. A free tracking app does the job.
