About BackMaxx
One developer, one app, one body part. Here is what BackMaxx is built on and where its limits are.
In one paragraph
BackMaxx is an independent iPhone app published by Ludovic PUAUD. It scores the back specifically — six zones and eight muscles from one photo — rather than the whole body, and builds a training plan from the order those scores come out in. It launched on the App Store on September 4, 2026.
What BackMaxx is
BackMaxx is an iPhone app that does one thing: it looks at your back and tells you which part of it is behind.
You take a photo with the selfie camera and a five-second timer. An AI vision model scores six back zones and eight back muscles, returns a Back Score out of 100 and a rank, and generates a training plan from the order those scores come out in: the lowest zone leads every session, the next two each get a slot of their own, and the remaining three keep enough volume to hold what they have. Re-scan weekly and that order re-sorts as zones catch up.
The reason it exists is narrower than it sounds. You cannot see your own back. You can see your arms in a mirror, you can feel your chest working, and you can watch your legs move — but the largest muscle group on your body is the one piece of you you have never actually looked at while training it. Most people train their back by feel and by habit, and then wonder why it has not changed shape.
Why only the back
Every other app in this category scores the whole body and returns one number. That number tells you very little, because “your physique is a 6” is not something you can train.
Six zone scores and eight muscle scores are something you can train. If your Lat Width reads low and your Upper Back reads high, the answer is vertical pulling, not more rows — and a whole-body score cannot tell you that. Specificity is the entire product.
Who builds it
BackMaxx is published by Ludovic PUAUD, working independently. It is not backed by a gym chain, a supplement brand or a media company, and it carries no advertising. There is no growth team; the app, the backend, the illustrations and every page on this site come from one place.
That is worth stating plainly because it cuts both ways. It means the app has no commercial reason to tell you that you need a supplement, and no incentive to keep you scrolling. It also means BackMaxx is not a clinical product and does not claim clinical authority — see the next section.
What BackMaxx is not
- It is not a medical device. The scores are visual estimates for training motivation. They are not measurements, not a diagnosis and not advice. Nothing the app outputs should inform a decision about your health.
- It is not a body-composition tool. It does not estimate body fat, weight, or measurements. It reads how developed the muscles of your back look.
- It is not an attractiveness score. It scores trainable muscle development and hands back a training plan. It does not rate faces, proportions you cannot change, or people.
- It is not a coach. The plans are generated from the data you give it. They are not supervised programming.
What the content on this site is built from
Every page here is written from the app’s own data, not around it:
| Asset | What it is |
|---|---|
| The exercise library | 77 movements, each tagged with its equipment, primary and secondary zones, the muscles it loads, a difficulty tier, default sets and reps, and a written coaching cue |
| The illustrations | 72 three-frame movement sequences, adapted from Everkinetic via workout-guide under CC BY-SA 4.0. Not stock photography, and not ours either — see the credits. |
| The zone and muscle model | The same six zones and eight muscles the app scores, with the same payoff lines it shows you |
| The rank ladder | Nine tiers with fixed score bands, compiled into the app so a rank cannot drift between releases |
When this site states a count, that count came from querying the corpus. When it quotes a payoff line, that is the line the app itself shows.
The app
iPhone, iOS 26 or later. Free to download, with an optional BackMaxx Pro subscription (weekly or yearly) for unlimited scans and the full plan. There is no Android version and no web version — this site is a place to read, not a place to sign up.
Launched on the App Store on September 4, 2026.

Frequently asked questions
Who made BackMaxx?
Ludovic PUAUD, working independently. The app, its backend, its illustrations and every page on this site come from one developer. There is no company behind it, no advertising in it, and no supplement brand attached to it.
Is BackMaxx a medical or clinical tool?
No. It produces visual estimates of muscle development from a photograph, for training motivation. It is not a medical device, it does not diagnose anything, and it does not measure health or body composition. For any health question, ask a clinician.
What makes BackMaxx different from whole-body physique raters?
Scope. Every comparable app scores your whole body and returns one number, which is not actionable. BackMaxx scores six back zones and eight back muscles separately, so the output is a specific answer — this zone is behind, run this block — rather than a rating.
Where do the exercise illustrations come from?
They are adapted from Everkinetic’s open exercise art, by way of Bryl Lim’s workout-guide project, and remain licensed under CC BY-SA 4.0. BackMaxx selected the back-training subset and re-encoded the frames for the web. Full credits are on the attribution page.
