How do I unregister a powermeter? January 27, 2022 22:37 Updated Open the 4iiii app, and connect with your Powermter. Select your Powermeter from the Devices screen to access Device Settings. Select Unregister Device. Related articles I don’t see my device on the list but I know it is turned on? I have a single side powermeter and know that I have a left/right leg power discrepancy. Can I adjust for this? On the previous app there was the ability to turn on "3rd Party App" compatibility but I can't find that setting in the new app. What do I do? I have lost my PRECISION battery cap. Where can I find a replacement? Do I need an account to use the Sport App?
