Medication Intelligence
Real pharmacokinetic modeling — not just a percentage. Watch your medication accumulate, peak, and decay across your entire journey, so you understand why week four feels different from week one.
See "2.34 mg in your body," not a vague percentage — modeled on each drug's published half-life.
Watch your levels build week over week as you titrate, and know what to expect after each dose.
Exact days until your next injection, plus an injection-site map so you never hit the same spot twice.
Everything in one place
Your medication, your nutrition, your training, and your coach — all built around the way GLP-1s actually work. Tracking is free, forever. The AI is what you upgrade for.
Log every injection, rotate sites, and see your real medication levels. The core of Momentum.
Track weight, water, and your daily Momentum Score out of 100. See your trend, not just today's number.
A daily check-in for energy, mood, sleep, and side effects — so you can see patterns over time.
An AI coach that can see your doses, weight, meals, and workouts — so its answers are based on your data, not generic advice. 24/7.
Upload any lab report and Momentum extracts your biomarkers, each on a clean range bar — so you can see how your body is responding, not just the scale.
Personalized 7-day meal plans with auto-built grocery lists. Targets calculated from your body, activity, and medication.
Point your camera at any meal for instant macros. No barcode, no manual entry — just snap and log.
Weekly workouts built for training in a GLP-1 deficit, designed to help you hold onto muscle as the weight comes off.
Photo progress, body-composition estimates, and smart trend detection so plateaus never catch you off guard.
I lost 50 pounds in 21 weeks on Zepbound — and the hardest part wasn't the shot. It was everything around it. Tracking doses in my Notes app, guessing at protein, wondering if I was losing muscle along with the fat. Nothing was built for this. So I built it.
— Cory, Founder of Momentum
