Objective strength data, straight from the muscle.
ARIS is a wearable band and companion app that measures muscle expansion directly — so the reps, load and effort your clients log outside your room are real numbers you can act on.
Most trackers guess your reps. ARIS measures them at the source.
Three ways to count a rep. Only one of them reads the muscle itself.
Camera-based apps
Watch the body through a phone camera and infer the rep from silhouette movement.
IMU / motion sensors
Detect acceleration and orientation, then infer that a rep probably happened.
ARIS FlexR band
Measures muscle expansion directly — the physical change in the muscle as it contracts.
FlexR is our proprietary sensing technology — a genuinely new approach the rest of the market isn't using.
Built for your practice
Whoever you are, the same thing is true: the work happens without you in the room, and you need to see it.
See whether the home programme was actually done — and how hard it felt — before the next appointment.
Programme once, then coach from real load and effort data instead of self-reported sets.
A hardware product with a differentiator you can demonstrate in 30 seconds on the floor.
Consistent, comparable strength measures across sites, teams and cohorts.
Assign a plan, then watch adherence and effort come back per client — the drop-off is visible before the next appointment, not after it. Console accounts are set up by invitation: request access and we'll open one for your practice.
Muscle is the tissue that decides how the next thirty years go.
Strength is not cosmetic. It underwrites metabolic health, balance, and the ability to keep living independently — and it is one of the few things that responds directly to what you programme for someone.
ARIS attributes every set to a muscle group, so the balance stops being a guess.
Everything the session leaves behind.
Reps counted from muscle expansion, not from motion or video.
Sets, reps, tempo, power and perceived effort per session.
Multi-week programmes that keep running when the client leaves.
Who trained, how often, and whether the trend is going the right way.
Client data is encrypted, access-controlled and never sold.
The app assists your programme — it never replaces your judgement.
How it works
Build a multi-week programme from your own routines and assign it to the client in the console.
The FlexR band pairs to the app and reads every set — at your facility or at home.
Completion, effort and progress land in your dashboard before the next appointment.
Install in 30 seconds
Android evaluation build, installed directly from us. No account or store login required to look around.
The "unknown source" security prompt is normal for direct installs — Android shows it for any app not installed from the Play Store.
The APK downloads straight to your phone.
Tap "Settings" on the prompt, flick the toggle, come back.
Demo mode runs without a band, so you can see the whole flow.

Clinic pilots, multi-site deployments, distribution — tell us the shape of it and we'll come back within two working days.
