User reviews

Best Bluetooth eBike app for DIY

Love the web interface support to upload and analyze rides. I download and post-process the CSV version to review my effort and battery usage.

Game changer

MAKES YOUR RIDE LEGAL TO OWN ! By adding and setting your Megan to a custom mode that stops all power to the VESC’s except for braking, your ride behaves just like a pedal bike and is legal to own and can be proven to a passing police officer it’s not powered mobility and so not a motor vehicle.

Amazing! Epic

This app is crazy good it allows unprecidented dexterity for the user to customize layouts, supports Apple watch, has user configurable alerts, can program vesc, has cloud support for records, great support from developer. This is next level and fundamental. Great app 100% recommend.

Simply Amazing Esk8 App

Keep up the great work! Always love the Metr App

Amazing app

An indispensable app designed for almost required hardware. This app is such a perfect example of what a community of contributors can come up with.

The app itself is simple enough to use and the devs are frequently updating and adding new features. It works flawlessly with their hardware and gives you more info than you may even need about your board and it’s performance. You can even export the info and create overlays in your videos.

The hardware is equally amazing. Simple to add to your DIY setup, easy to program and it works perfectly.

The combo adds features you can maybe get some of elsewhere, but it does it far better and adds many, many other features you’ll never find in another app/ hardware combo.

I can’t speak enough good of the METR teams efforts. I wouldn’t bother building a board without a METR pro and I know I don’t have to look anywhere else for the best hardware and software.

They’re great guys to chat with if you need some help also.

Pick up your BT transceiver and download this software. You won’t regret it.
