New: meet Recco. A redesigned setup that builds your recomposition
plan in two minutes — then tracks the waist and lifts that actually
show progress.
Lose belly fat. Build muscle. At the same time.
That's body recomposition — and it's why the scale lies to you. Train for a month and the number barely moves, because you added muscle while losing fat. Same weight, completely different body.
RecompX tracks what actually changes: your waist, your lifts, and your protein.
WHO THIS IS FOR
You're not overweight, but you're not lean either. The scale says you're fine; the mirror disagrees. Soft middle, not much muscle underneath — the pattern people call skinny fat.
Most fitness apps assume you want to lose weight. You don't. You want to change what your weight is made of. That takes a different approach: lift to build muscle, eat enough protein, and track the numbers that actually move.
WATCH YOUR WAIST SHRINK
Waist-to-height ratio predicts visceral fat — the kind stored around your organs — far better than BMI or bodyweight. Log a measurement in seconds and watch the trend fall.
Start with a 60-second check: measure once, and RecompX shows you where you stand and what to do about it.
TRAIN THE RIGHT MUSCLES
Get a plan matched to your equipment — bodyweight at home, a pair of dumbbells, or a full gym. No guessing which exercises to pick.
Every exercise shows exactly which muscles it works, with photo demos and a full-body muscle map. Primary movers in gold, supporting muscles in green. You always know what you're doing and why it matters.
GET STRONGER EVERY WEEK
Estimated 1RM trends for every lift. When your numbers climb, that's muscle being built — visible even in the weeks the scale sits still.
This is the proof most apps never show you. Weight loss apps track one number going down. RecompX tracks strength going up, which is the whole point of recomposition.
LOG A SET IN SECONDS
Last session's numbers are already on the row. Tap, type, done. No menu-diving between sets, no hunting for what you lifted last time.
Rest timers, plate math, and set history stay out of your way until you need them.
HIT YOUR PROTEIN
Protein is the single biggest lever in recomposition — it's what lets you build muscle while losing fat. RecompX gives you a target based on your body and tracks it with one tap, no food diary required.
No calorie counting. No weighing your rice. Just the one number that matters most.
ASK RECCO, YOUR AI COACH
Recco knows your plan, your lifts, and your measurements. Ask why your waist stalled, whether to cut or bulk, or how to swap an exercise you can't do — and get an answer grounded in your real data.
Plain English, not gym jargon. No question is too basic.
LEARN WHY IT WORKS
Two-minute lessons on training, nutrition, recovery, and mindset. Enough to make good decisions on your own, without a nutrition degree or a YouTube rabbit hole.
Understanding why beats following instructions. You'll stick with it longer.
BUILT FOR BEGINNERS
No calorie obsession. No bro-science. No assumption you already know what a hypertrophy block is.
Just the handful of things that actually move the needle: lift hard, eat enough protein, track your waist, and stay consistent long enough to see it work.
RecompX is free.

Ratings & Reviews
A brand-new onboarding experience, plus fixes from your feedback.
• Redesigned onboarding — Recco now walks you through an illustrated
story, from waking up to arriving at the gym.
• Built for more bodies — nutrition questions now cover ten cuisines
instead of three, so your tips actually match how you eat.
• Better measurements — height entry in feet/inches or cm, and your
waist reading now includes a 12-week projection.
• Faster plan setup — single-choice questions advance automatically,
and you see your plan built before you're asked to sign up.
• Vote on what we build next — a new roadmap board in Profile, where
you can back existing ideas or submit your own.
• Fixed: replacing an exercise could add a duplicate to your workout.
• Fixed: creating a custom exercise could hang; exercise history now
sorts correctly.
• Various loading and layout polish throughout.
