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!

Accurate and so easy to use. Great add!!

Dad101 not worrying as much.

When I was younger I tried most vert programs out there and ultimately used one that mixed a few. My focus was vert for basketball. Part of the program is dunking off of different legs from different angles. Did that program with Vert and it measured every dunk perfectly on my iPad on the side of the gym. I have one for each of my two boys.
I also use it with crossfit workouts measuring box jumps and height on burpies. It was easy to dog it and not get off the ground until now. Really cool product, easy to power and use and a great way to enhance my Bball vert and crossfit workouts. I've recommended to friends. Nice work on this device and app!

Needs some work


This app only works with the vert sensor.

The app crashes quite a bit on my iPhone 5 and iOS 8. It crashes. A lot. For example if I play 7 vball games to 25, 4/7 of the time, the app has crashed when I check my phone after the game.

It could use a way to edit sessions on the phone instead of just on the website.

It would be nice if the app could pull the best jump from your sessions and not just when "training".

For picture talking create a mode to trigger the shutter when at the peak of your jump for the best props pictures.

When in session get the app to disable the auto lock feature.

It needs some work and it's the only app that works with the sensor so it's all you got until they improve upon it.
