FITMUST
Fits Your
Palm.
For a
Reason.

The average human palm is 9.2 cm. We didn't land on 9.1 by accident — assessments should be effortless to hold, not a workout in themselves.

Why Clinicians Choose FITMUST

You Already Know
What You Need.
We Built FITMUST.

01

Instant Readout

The Number
Is Right There.
On the Device.

Built-in display shows peak force the moment the test ends. Glance, note, move on — no phone needed.

02

Protocol Standardisation

Every Test.
Same Standard.
Every Clinician.

Reference GIFs in the app guide each protocol step-by-step — so your juniors run the same quality assessment you would.

Team Screening

Assess the
Whole Squad.
Same Session.

Clinician shows athlete their results in real time. One device, one session — the entire team screened and results shared on the spot.

Measurement Suite

Every Metric
FITMUST Tracks.

Force Output

Peak Force

Max voluntary contraction in kgf. The single number that defines how strong a muscle is right now.

📈

Explosive Power

Rate of Force Development

How fast force builds — the key predictor of athletic readiness and return-to-sport clearance.

⚖️

Symmetry

Limb Symmetry Index

Left vs right balance expressed as a percentage. Below 90% LSI flags elevated re-injury risk.

〰️

Session Mean

Average Strength

Consistent output across all reps — a more stable baseline than peak alone for tracking rehab progress.

📅

Longitudinal

Progress Tracking

Session-over-session trends plotted automatically. Show patients exactly how far they've come.

👥

Efficiency

Group Screening

Assess a full squad in one session. Flag strength asymmetries before they become injuries.

📄

Reporting

PDF Strength Reports

Shareable patient-facing reports generated instantly. Visual, clear, and doctor-ready.

🎯

Flexibility

150+ Protocols

Validated protocols for 16+ muscle groups — or build your own. The app guides every test step by step.

🏆

Return to Sport

RTS Criteria

Quad-to-hamstring ratios, deficit targets, force development benchmarks — all in one test session.

Our Approach

Built on
Research.
Not Specs.

We started with what clinicians actually needed, then built backwards. Four years of field testing with sports physios, orthopaedic surgeons, and performance coaches shaped every decision.

Every protocol clinically validated before it ships.
Device dimensions designed around the human palm — not manufacturing convenience.
App built by physios, for physios — not repurposed fitness software.
ISO 13485 certified. NABL-traceable accuracy. Accountable from day one.
4+ Years in the Field
2.7L+ Rehab Data Points
NABL Lab Validated

Evidence Base

FITMUST Research.
