Muscle Bvll is an AI nutrition and training system. Log food and lifts in a tap; its AI reads your weigh-ins, photos, and recovery, proposes the change — you accept, and the whole plan moves.

What's inside the loop
How it works
PROGRESS ANALYSISWhat You'd Pay Separately
Programs your sessions, adjusts for injuries, times your deloads. Your training brief is ready every morning.
Sets macros, plans meals from your real pantry, builds the grocery list. Adjusts when you eat or shop.
Reviews progress photos, tracks your numbers, tells you what to change. On demand, no appointment needed.
That's $450–900/mo for the same job, all of it in one app for $25/mo.

Lifters who want muscle — with a system behind it. Nutrition, training, and body tracking in one place, plus an AI that reads your progress and moves the plan. You bring the effort; it runs the plan.
Food is a line or a photo — type it, say it, or snap it and the AI structures it. Your workout is already the day's brief, so a set is one tap. Bring your own program or meals as-is.
It reads what you log and track, then proposes one specific change at a time. A weigh-in re-reads your real maintenance and proposes a new calorie target; a rough week pauses a lift's climb, so it repeats instead. Accept a recommendation and macros, meals, and training move together. Every change is logged.
Apple Health, Health Connect, and Oura — your watch, ring, and scale feed the loop:
HRV and sleep shape today's training: the climb pauses when you're under-recovered and pushes on when you're primed.
Your watch's measured calories replace the workout estimate, so nothing is double-counted.
Weight logs itself when your scale syncs — your trend and calorie target stay current.
Photo and scale body-fat readings blend into one number for your body model and protein target — and your manual entry always wins.
You decide. It proposes every change, and nothing moves until you accept. Auto-apply, if you turn it on, handles only small, high-confidence nudges — each with one-tap undo. Everything stays overridable.
Double progression, run for you: it climbs your reps, then adds weight in real plate jumps, with dropsets, supersets, and auto-deloads. Log a hard top set and it recomputes your training max. Reshape it in plain words anytime.
Yes — your first 10 logs are free, no card. Then it's $25/month, everything included. Log a few meals and a workout, watch the AI work, then decide.
Any browser, a Windows desktop, and Mac and iOS apps — one account, all in sync (Android's on the way). Your data is yours: export food, lifts, weight, measurements, and recovery to CSV anytime from Settings.
