Measure your real muscle force in kg. No lab. No excuses.
Zimetrix is the portable smart dynamometer that measures your max force, your RFD (explosiveness) and your bilateral symmetry in under 10 seconds. Stop estimating your 1RM: now you see your real strength in kilograms on your phone, after every session.
Use it once a week like a bathroom scale… but for strength, power and real explosiveness.
- Clinical-grade precision in the size of a TV remote
- Compatible with 30+ isometric strength tests

The problem nobody talks about
You've been training hard for months. But you have no idea if you're actually getting stronger.
How much real force can you produce today? What about last week?
You program loads based on a 1RM you estimated three months ago.
You don't know if one side of your body produces 20% less force than the other - until the injury hits.
You confuse 'feeling tired' with 'being adapted'.
The scale doesn't tell you. The mirror lies. And adding 2.5 kg to your squat could be technique, energy or a good day. Not real strength.
What if you could see your strength as clearly as you see your weight on a scale?
That's exactly what Zimetrix does. What gets measured gets improved.
What is Zimetrix? The portable dynamometer that turns any bench, ring or floor into a strength lab.
Zimetrix is a smart isometric dynamometer the size of a TV remote. You anchor it, pull or push at max intensity for 5 seconds, and the app returns data you used to only see at elite performance centres.
Works with:
Deadlift · Squat · Bench Press · Rows · Overhead Press · Pull-ups · Curls · Hand grip · Rotator cuff · and more
Max Force
Your true peak force in kg with clinical-grade precision
Explosiveness (RFD)
How much force you produce at 100, 200 and 300 ms
Isometric Endurance
How long you can hold near your maximum
Bilateral Symmetry
Left vs right side difference, in %
No plates. No spotter. No gym.
Three minutes per session. Data that used to cost €25,000.
Standalone Mode
No phone. No app.
Built-in screen showing live force and basic metrics instantly. Ideal for quick sessions or places with no phone.
App Mode
Where the magic happensiOS and Android
- → Pair with the device in 2 seconds via QR scan
- → Every measurement saved forever, synced to the cloud
- → Clean charts, force-time curves, RFD, symmetry % and session-by-session comparison

Track and review every exercise and session
See detailed charts with your real progress, not estimated
Who is Zimetrix for? For anyone who trains (or coaches) and takes strength seriously.
Three profiles. Three ways to use it. Same principle: stop guessing, start measuring.
Stop estimating your progress
If you train 4+ days a week, Zimetrix tells you every week if you're stronger, plateauing or need to deload:
- Spot plateaus before you waste months
- Program loads based on this week's real force, not 3 months ago
- Fix left/right asymmetries that are silently holding you back
Back every decision with objective data
Manage all your athletes from one dashboard. Track progress, set goals and share professional reports. No spreadsheets, no subjective 'you're doing great'.
- Manage up to 10 athletes per subscription
- See history, personal best and average improvement for each
- Set strength goals and get alerts on progress
- Export branded PDF reports per athlete
- Pair multiple devices via QR in under 5 seconds
Return-to-play with objective criteria, not 'looks fine'
The same metrics used at elite performance centres, at a fraction of the cost of an isokinetic. Measure RTP with data, quantify bilateral deficits post-ACL, post-shoulder or post-ankle.
- Peak Force and Time to Peak
- RFD 100 / RFD 200 / RFD 300 ms
- Exportable force-time curves
- Bilateral symmetry analysis with clinical thresholds

What the people already using it are saying
Athletes, coaches and physios who stopped guessing and started measuring.
“I was stuck at 110 kg bench for 8 months. With Zimetrix I found out my right side was producing 18% less isometric force than my left. Three months fixing the deficit and I jumped to 122.5 kg.”
Mike J.
Intermediate powerlifter, London
“I see 40 clients a week. I used to tell them 'you're improving'. Now I show them a chart with their real strength. Retention went up 35% in the first quarter.”
Sarah K.
S&C Coach, Manchester
“We use it for post-ACL rehab. Going from visual cues to having bilateral symmetry in kg has changed our discharge criteria. The cost-benefit vs an isokinetic is brutal.”
Dr. Andrew P.
Sports physiotherapist, Dublin
FAQ
Frequently Asked Questions about Zimetrix
Zimetrix works with any exercise where you can anchor the device and push or pull against it: isometric deadlift, squat, bench press, rows, overhead press, pull-ups, curls, hand grip and shoulder rotators, among many others.
Anchor it to a bar, rack, ring, strap or the floor. Any fixed point works. The app ships with 30+ preconfigured protocols ready to use.
No. The Zimetrix device works completely standalone. It has a built-in screen showing your live force and basic metrics instantly. No phone needed.
That said, the app is where the magic happens: unlimited history, advanced force-time curves, RFD 100/200, bilateral symmetry analysis and session-by-session comparison over time.
Zimetrix uses professional-grade load cells (typical accuracy of +/- 1% of full scale). You get the same kind of measurements elite performance labs use, but portable and within reach of anyone.
Yes. Each client can scan the device's QR to log in instantly and save their measurements to their own cloud profile. The Trainer L1 plan includes 10 premium accounts for your athletes at no extra cost to them.
You can also export branded PDF reports per athlete and manage all your devices from one dashboard.

No. A VBT encoder measures the velocity at which you move the bar in dynamic exercises. Zimetrix measures the real isometric force you produce against a fixed resistance, in kilograms. They are complementary tools answering different questions: VBT answers 'how fast did I move X kilos', Zimetrix answers 'how much force can I produce today'.
Yes. It's one of the most powerful use cases. You can quantify bilateral deficits after an ACL, shoulder or ankle injury and make objective return-to-play (RTP) decisions instead of relying on 'looks fine'. It's an affordable alternative to a €25,000 isokinetic dynamometer.
Powerlifting, weightlifting, crossfit, calisthenics, rugby, football, basketball, climbing, athletics, tennis, combat sports and any discipline where max force, explosiveness (RFD) or bilateral symmetry drives the outcome. It's also ideal for sports physiotherapy and rehabilitation.
Stop training blind. Start training with data.
Every week you go without measuring your real strength is a week where you don't know if you're progressing, maintaining or heading toward an injury from asymmetry.
Progress you can see. Progress you can feel.
Not estimated. Not guessed. Measured in kilograms.
