Remote care management · FlexR sensing

Prescribed is not the same as performed.

The FlexR band measures muscle expansion on the limb you're rehabilitating, so every home session becomes a record — sets, load and effort you can review, document and act on before the next appointment.

Proprietary FlexR sensing
Our own sensor technology, developed in-house — direct muscle measurement, not motion inference.
An NUS spin-out, since 2018
Microtube spun out of the National University of Singapore; ARIS is built with clinicians and coaches.
The right metric

A step counter can’t count a squat.

Strength isn’t measured in heartbeats. A programme is dosed in sets and reps — here is the same set of eight through two sensors.

Why muscle

Muscle decides how the next thirty years go.

Strength underwrites metabolic health, balance and independence — and it responds directly to what you prescribe.

01
Sarcopenia starts earlier than people think
Muscle mass is commonly cited as declining from around 30, accelerating after 60. Progressive resistance training is the most reliable countermeasure.
02
Balance matters more than volume
Push against pull, upper against lower. Any group left out becomes a weakness — the trained side compensates, and that is where re-injury starts.
03
Strength tracks healthspan
Functional strength is among the better markers of how well someone moves and recovers later in life. Keeping it is a long game — so adherence is the whole battle.

ARIS attributes every set to a muscle group, so the balance stops being a guess.

Shading follows the last 14 days — the deeper the fill, the more work that group took.

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.

Rehab & clinics

See whether the home programme was actually done — and how hard it felt — before the next appointment.

Coaching & gyms

Programme once, then coach from real load and effort data instead of self-reported sets.

Distributors & resellers

A hardware product with a differentiator you can demonstrate in 30 seconds on the floor.

Enterprise health

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.

In the app

The coaching happens between appointments.

Your patient opens the app and is walked through the session you prescribed. Everything it records comes back to you.

Guided sessions

The app runs the prescribed session — exercise, sets, rest — so nobody is guessing at home.

Live rep counting

Each contraction is counted at the muscle and shown as it happens, with tempo and effort.

Muscle map

Fourteen days of work shaded onto the body, so gaps are obvious to patient and clinician.

Multi-week programmes

A plan that keeps running after the appointment, with progression built in.

Progress they can feel

Streaks, personal bests and week-on-week volume — motivation that is not willpower.

Straight to your console

Every session syncs to your dashboard and into the exportable clinical report.

How it works

1
You set the plan

Build a multi-week programme from your own routines and assign it to the client in the console.

2
They train with the band

The FlexR band pairs to the app and reads every set — at your facility or at home.

3
Results come back to you

Completion, effort and progress land in your dashboard before the next appointment.
