What it does

Connect a Bluetooth trainer and record power, heart rate and cadence every second, with an ERG interval timer and live power zones. Afterwards you get FTP detection, fitness and fatigue trends and a plain-language report.

Getting started

Free with no trial and no card: ride in Chrome or Edge, or install the macOS, iOS or Android app. On a Mac the numbers can sit in the menu bar while you watch something else.
