Shotsy vs GLP-1 Coach: Which Tracker Wins?

Written by the GLP-1 Coach editorial team. Last updated August 23, 2026.

Shotsy and MyGLP1 (GLP-1 Coach) are probably the two most-compared GLP-1 tracker apps right now — and for good reason. They overlap on the basics (injection logging, reminders, weight tracking) but diverge quickly once you dig past the home screen.

This comparison is written by the team behind MyGLP1, so you should read it with that context. We've tried to be accurate about what Shotsy does well, because the goal here is to help you find the right tool — not to win a marketing comparison.

What Shotsy does well

Shotsy has been on the market longer and has earned its review base — more than 30,000 App Store ratings at 4.8★ and thousands of Google Play ratings. That's a meaningful signal. It didn't get there by being bad.

Its strengths:

• Low-friction injection logging — tap to log a shot, minimal steps; both apps have injection logging, but Shotsy's is intentionally minimal where MyGLP1's adds injection site rotation tracking
• Established reminders — push notifications with a multi-year track record; both apps offer reminders, but Shotsy's system is older and has the reliability history to show for it
• Pen inventory tracking built into the log flow — doses remaining decrements automatically as you log each shot, with no separate tool to open
• Large, established community — more users means more forum discussion, more third-party reviews to cross-reference

If you want a low-friction shot log with a solid reminder system, Shotsy earns its rating.

What MyGLP1 does differently

MyGLP1 was built with a different premise: tracking the shot is the easy part. The harder part is making sense of what's happening week over week — why appetite feels different at week 6 than week 3, whether a plateau is a real stall or just muscle composition shifting, whether your symptoms are dose-related or something else.

That shapes everything about the app:

• Injection logging with site rotation — logs each injection and tracks which body zones you've used recently (arms, abdomen, thighs), surfacing which site to rotate to next. The same check-in captures dose, symptoms, and weight in one step rather than separate screens.
• AI check-ins — after each weekly check-in, you get a coaching response generated from your actual data: your dose level, your trend, your reported symptoms, your phase of therapy. Not a generic tip.
• Pharmacokinetic level curve — a visualization of how your medication is building up in your system over time, based on published half-life data. Useful during titration to understand why appetite might feel different at different points in the dosing cycle. Try the doses remaining calculator to see the same underlying math.
• Compounded medication support — compounded semaglutide and compounded tirzepatide are first-class options with identical features to their brand-name equivalents, not afterthoughts.
• Muscle preservation focus — the dashboard surfaces protein and body composition context, because muscle loss during GLP-1 therapy is the underreported outcome most apps ignore.
• Protein tracking — integrated with the protein calculator to help you hit the higher targets required to protect lean mass at a calorie deficit.

Partial = app may support the medication label; verify current medication list in the app before relying on this. † MyGLP1's reminder system (push + email) is live as of mid-2026; the underlying infrastructure was rebuilt this year — feature is functional but doesn't have Shotsy's multi-year reliability track record yet.

Who should use Shotsy

Shotsy is the better fit if:

• You want the simplest possible injection log with reliable reminders
• You want pen inventory tracking baked directly into the shot-logging flow (no separate tool to open)
• You prefer a large established community with lots of third-party reviews to browse
• You don't need coaching or trend analysis — you just want to record the shot and move on

Who should use MyGLP1

MyGLP1 is the better fit if:

• You're on compounded semaglutide or compounded tirzepatide and want full feature parity with branded medication users
• You want week-over-week coaching that responds to your actual pattern, not a generic tip
• You're concerned about muscle loss and want the app to actively surface protein and body composition context
• You're in a titration phase and want to understand why appetite or energy feels different at different points in the dosing cycle
• You're on a newer or less common GLP-1 (retatrutide, orforglipron) and want an app that's already built for it

The bottom line

One more thing worth knowing: Shotsy raised $2.25M in VC seed funding in February 2025, backed by Adverb Ventures, Coalition Operators, Springbank Collective, and angel investor Esther Dyson. MyGLP1 is independently built and self-funded. Neither is inherently better — venture backing can mean faster feature development; independent means no pressure to grow revenue beyond what the product actually needs. Just know what you're supporting when you subscribe.

Bottom line: Shotsy is a well-rated, established injection logger with strong reminders and a pen inventory system built into the shot log — a solid choice if low-friction logging is the priority. MyGLP1 is built for a different user: someone who wants the data to actually explain what's happening week over week, not just record that it happened. If you're on compounded medication or want AI coaching that adapts to your trend, that's the gap MyGLP1 is designed to fill.
