Digital Handheld Dynamometer · ISO 13485
Measure
Strength.

More.
FITMUST is a digital dynamometer that measures isometric muscle force and sends it live to your phone. One device, 150+ validated protocols.
Form Factor
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.
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.
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.
Connected App
Test Done.
Report Ready.
Instantly.
Full strength report generated the moment you finish. Patient name, test date, bar charts, LSI — shareable as PDF. Android & iOS.
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.
Evidence Base
FITMUST Research.
Peer-Reviewed.
In Every Kit
FITMUST Calibration Certificate
Included.
Every FITMUST ships with a NABL-traceable calibration certificate. Your readings are accountable from day one.
