How to Choose the Right GLP-1 Tracker App for You

Written by the Regimen team · Last verified July 5, 2026

The good news: there are a few genuinely solid GLP-1 apps now, and they're built for different kinds of people. Whether you're on Wegovy, Zepbound, Mounjaro, or Ozempic, the trick is matching an app to how you're doing this, from your white-knuckle first month to steady maintenance. Here's the honest rundown.

Quick disclosure: we make Regimen, so this isn't an independent review. We try to earn your trust by saying plainly where the other apps are better.

At a glance

They're all legit. It comes down to what you want most.

What actually matters in a GLP-1 tracker

• Does it help you make sense of the week? The nausea on day 2, the easy days 3 to 5, the food noise creeping back by day 6. That rhythm is the whole experience, and there's a real gap between an app that records it and one that helps you see it.
• Does it help with food? GLP-1s crush your appetite, so getting enough protein and water is a real daily struggle. Some apps make this central; some don't do it at all.
• Will you actually keep using it? If logging feels like a chore, you'll quit by month two. Simple wins.
• Does the pricing stay honest? Nobody likes a free app that suddenly locks the good stuff away. Check what's free before you get attached.

Match it to how you're doing this

• Getting your protein and food dialed in is the main thing. MeAgain or Shotsy. Both do food logging well, and we'll be straight: Regimen doesn't do food logging, so if that's your number one, start there.
• You mostly want to see your medication level through the week. Glapp does exactly that, cleanly. It shows how the medication behaves across the week based on the clinical data, which people genuinely love.
• You want the popular, simple, proven pick. Shotsy.
• You want to understand what's actually going on with you week to week. That's what we built Regimen for.

If you want to understand your week

Most apps log your shot and your weight, then leave you scrolling back through your entries trying to work out why Thursday was rough. Regimen connects the dots for you. You track the stuff that actually moves your week (food noise, nausea, energy, sleep, constipation, injection-site soreness, whatever hits you), and Regimen's Signals feature watches those check-ins and tells you the pattern it finds: your food noise tends to creep back around day 5, or your energy dips as the dose wears off.

Glapp compares you to the clinical average; Regimen compares you to you. You also get your medication-level curve on the free tier (the one Shotsy currently keeps behind premium), plus progress photos for when the scale stalls but you can clearly see you're changing.

The honest bottom line

If food logging is your one must-have, MeAgain or Shotsy are the right call, plainly. But if you want more than a shot log, Regimen is the clearest fit for understanding your GLP-1 week. Here's the one-line version: the other apps record what happened; Regimen helps you see why. Your dose, symptoms, weight, cravings, and photos in one place, with the patterns surfaced for you instead of left for you to hunt down. Track as much or as little as you want.

So the honest recommendation set: Shotsy for the popular simple pick, MeAgain if food's your focus, Glapp for the medication-level view, and Regimen if you want to actually make sense of your week instead of just logging it.
