WHY WE MADE FREZ DYNO

We made Frez Dyno because objective strength testing should be practical enough for everyday training—not limited by the price of measurement hardware.

So we kept the device compact, focused, and priced as low as possible, helping more people start measuring and use objective data in regular training.

Frequently Asked Questions

What does Frez Dyno measure?

Frez Dyno measures force in real time through the Frez app, helping you understand Peak, Endurance, and RFD instead of relying only on feel.

Can I use Frez Dyno without a subscription?

Yes. The Free plan lets you measure Peak and track your results, create up to four grips and training sessions, and use the training scheduler. You can also measure Endurance and RFD, but those results are not saved on Free.

What does Frez Pro unlock?

Frez Pro is optional. It helps you unlock the full potential of your training data with unlimited grips and sessions, advanced training tools, advanced metrics, and data export.

What are the key specifications?

Frez Dyno has a recommended load of 200 kg, a maximum load of 300 kg, a 250 Hz sampling rate, and a USB-C rechargeable 300 mAh battery.

Are the carabiner and handle bar included?

No. The carabiner and handle bar shown in the product images are props and are not included.

How does Frez sustain this model?

Instead of relying on a large one-time hardware margin, optional Frez Pro subscriptions support the ongoing work behind the app: servers, reliability improvements, maintenance, customer support, and new analysis.

We plan to keep core features such as measurement and recording free whenever possible. This lets more people start with Frez while allowing us to keep supporting and improving the service over time.

⚠️ NOTE

The carabiner and handle bar are props and are not included with the product.

Very responsive, light and compact. Especially compared to slow and bulky cheap chinese load cells.
Works flawlessly with Frez App. Very satisfied with the purchase. The shipment from South Korea to Poland took less than a week (however the shipping costs were very significant compared to the device price itself). Bought it together with the strap and the portable platform and damn is this comfortable. I was reluctant to spend 50$ extra on a piece of wood but it’s totally worth it. Light and sturdy. Very easy to set up. And the rotating carabiner works great. Very well thought-out

Really really cool gadget to use for training and testin, in a remarkable price too! My only suggestion would be for it to be able to keep up for at least more than 400kg. I think more higher level athletes will be able to use it this way. I really enjoyed using the product tho and I highly recommend!!! :))

This is a real game changer for me compared to the budget crane scale. Not only does it feel much higher quality and is much more compact, but its much higher sampling rate and incredibly fast response make for a completely different training experience.

Any change in applied force is visible immediately, so you can make adjustments on the spot instead of constantly over- or undercompensating. The device gives you much better feedback and makes training far more precise.

And all of this comes at such a fair price, with super-fast delivery. Excellent value for money to my opinion. I can absolutely recommend it.

I love how responsive the device feels and is going to be super helpful for rate of force development testing. It's even more compact then I was expecting and feels high quality too. I definitely recommend plus shipping was very fast to NZ

I’ve been using the Frez Dyno, and my overall impression has been very positive.

The device feels compact, solid, and easy to use, and the connection with the Frez app has worked smoothly for me. It’s especially useful for tracking finger strength and making training sessions more measurable and consistent.

For the price, I think the Frez Dyno offers great value, especially compared with other force measurement devices. I’m looking forward to using it more in my training.
