Why I built this
I've talked to hundreds of GLP-1 users through this site, and one complaint kept coming up: "I use MyFitnessPal for calories, a note in my phone for injections, a scale app for weight, and I have no idea when I'm supposed to increase my dose."
Everyone was cobbling together tools that weren't built for GLP-1. So I built one that is.
What the app does
Four things, done well:
1. Injection tracker
Log every injection. Rotate injection sites automatically. Get a reminder the day before your next dose. See your complete dosing history at a glance — critical when your provider asks "when did you increase to 1.0 mg?"
2. Weight and progress
Log your weight (as often or as rarely as you want). See your total pounds lost, your rate per week, and a clean chart of your journey. The app auto-detects when you've hit a plateau and suggests when to check protein and steps.
3. Protein target tracker
This is the one your provider actually cares about. GLP-1 users need 0.6–1.0g of protein per pound of goal weight to preserve muscle. The app calculates your target and lets you log meals with a single tap. Miss too many days? It nudges you.
4. Side effects log
Nausea, fatigue, constipation, sulfur burps — log them with severity and time. Over a few weeks, patterns show up you'd never see otherwise. Bring the log to your next appointment.
Plus: 100+ GLP-1 friendly recipes
Every recipe in the app hits three targets: high protein (30g+ per serving), moderate calories (400 or fewer), and easy on your appetite. Breakfast, lunch, dinner, and snacks — all optimized for how GLP-1 changes the way you eat.
Free forever. No credit card. No catch.
The app is 100% free. I built it because I wanted it to exist. If you want to support the site, share it with someone else on a GLP-1 — that's the best thank you.
What's coming next
The v1 launch has the core tracking features. Next up:
- Calculator suite — the 10 calculators from this website are getting rebuilt inside the app so you have everything in one place
- Community feed — anonymous progress posts, recipe swaps, dose milestones
- Provider export — one-click PDF summary to bring to your appointments
- Reminders — dose reminders, protein target alerts, weigh-in nudges

Get started
The fastest way to get value is to log your next injection through the app. Do that once, and everything else falls into place.
