Using the device is simple!


Almost all of the functionality of the OpenBarbell V3 above can be utilized directly from the screen and buttons on the device. With the latest release of our Open Source app, the possibilities are endless. We’ll provide the base functionality and everything that you need to control the device and get the data you want. We will also encourage anyone who makes improvements on the app to share them with the community so we can all benefit!


You can find your OpenBarbell V3 User Manual at our Wiki here and our FAQ here. The user manual will cover all the topics you would need to know, including detailed user instructions, how to access Inverted Mode, Oly Mode, and Power Mode, and how to take advantage of new app features. If you’re technically inclined, the user manual will also show how to upload your own firmware and modify the open source app!
