Keep your muscle while you lose the weight.
FitBrain is the strength-training app for people training on GLP-1 medication (Mounjaro, Wegovy, Ozempic, Zepbound). It also works great for anyone who lifts.

Why FitBrain
A coach that understands your medication
Generic loggers do not know about appetite changes or how to adjust training on low-appetite days. FitBrain does, and it focuses on protecting muscle while the scale drops.
Private by design
Log workouts free. The on-device coach keeps your medication and training data on your phone. FitBrain Pro adds a cloud coach for deeper analysis and plan generation, only with your consent.
A fast log that fits the gym floor
Sets, rest timers, templates, personal records, progress charts and Apple Health, in a clean iPhone app. No medication needed to use any of it.
A note from the founder
I started Mounjaro and kept losing strength as the scale dropped. My appetite swung week to week, and no workout app understood why my training suffered. So I built FitBrain, the app I wanted for myself.
