AI gym coach for iPhone

Know exactly what to do. Do it right.

Musclo gives you today's workout (sets, reps and weight), watches your form through the camera and tells you what to fix. Built for beginners who train when they can.

3 days free, then $39.99/year. Cancel anytime.

What it does

A coach for the three moments you get stuck.

Not sure what to do, not sure you're doing it right, not sure what that machine is. Musclo answers all three in seconds.

No gym today, I only have 20 minutes
No problem. Here's a 20-minute home workout, no equipment:
Push-up3 × 8
Split squat3 × 10 each
Glute bridge3 × 12
Plank3 × 30s

Just ask your coach

Talk or type. "My knee hurts", "the bench is taken", "how much weight?" You get a straight answer and a plan you can start with one tap.

Keep your hips up

Live form check

Prop your phone up and train. Musclo tracks your body on the device, counts clean reps and calls out fixes in big type you can read from across the room.

Lat pulldown · back, biceps

Scan any machine

Snap a photo of a machine you don't recognise. Musclo tells you what it is, what it works and exactly how to set it up.

Train when you can

Missed a week? Your plan doesn't care.

Most programs fall apart the moment life gets busy. Musclo plans one workout at a time from what you actually did.

A coach, not just a logbook.

Most workout apps are logbooks or plan generators. Musclo also talks back, watches your reps and knows the machines, in one app, for $39.99 a year.

FAQ

Questions

Is Musclo for complete beginners?

Yes. Musclo was built for people who don't know what to do at the gym. Every day it gives you a short list of moves with sets, reps and a starting weight, and shows you how to do each one.

Is my camera video uploaded?

No. The live form check runs entirely on your iPhone. Video is analysed frame by frame on the device and never recorded or uploaded. See the privacy policy.

What if I miss a week?

Nothing breaks. Musclo plans one workout at a time from what you actually did, so it picks up where you left off and adjusts the weights.

Can I train at home?

Yes. Pick the Home focus, or tell the coach you have no gym today, and you get a bodyweight workout.

Does it work with Apple Health?

Yes, if you allow it. Musclo can save your workouts to Apple Health and read sleep and recovery to suggest an easier day when you need one.

What is the best gym app for beginners?

The best gym app for a beginner tells you exactly what to do each day, shows you how, and checks you are doing it right. Musclo does all three: a daily plan with sets, reps and weight, demos for every move, and a live camera form check. See how it compares to Fitbod, Hevy and others.

Is there an app that checks your workout form?

Yes. Musclo checks your form live through your iPhone camera, counts clean reps and tells you what to fix, such as knees caving in or hips sagging. It runs on the phone and needs no extra hardware.

Can an AI app replace a personal trainer?

For most beginners an AI coach covers the basics a trainer gives you: what to do, how much weight, and form corrections, for about $3 a month instead of $50 or more a session. It doesn't replace a professional for injuries or medical issues.

How does the free trial work?

The yearly plan starts with 3 days free, then $39.99 a year. You get a reminder before the trial ends and can cancel any time in your iPhone Settings.
