A must workout tool!!!

I’m an athlete 🏀 and this device has helped me to measure my workout progress tremendously. Because it can measure my vertical jump height with accuracy i could see which exercise works or doesn’t. Also their customer service is amazing. They respond right away and give you all the answers with speed.

Years Ahead of Existing Vertical Measurement Technologies ...

I looked everywhere for a simple, wearable device to accurately measure vertical jump. I was surprised that none existed. Then I found VERT. I would have been elated at the small VERT device, and its capabilities, alone, but the app greatly enhances the utility and usability of the measurement data. I've designed leading edge electronics all my life, and I've found some companies lose their focus and vision in their products. Not Mayfonk Athletics ... They have designed an elegant and deceptively simple device and app that hides its absolute state of the art engineering to bring the customer a powerful and accurate product that is, at the same time, fun and intuitive to use. Great job Mayfonk Athletics!
