About

ZonePace is a free Android app for people who plan their training on Intervals.icu, and it needs an Intervals.icu account. It shows your calendar and plan, and runs the structured cycling and running workouts in it with interval timers, voice cues and live targets. On a Bluetooth FTMS smart trainer it sets the resistance in ERG mode to follow the power targets, or you ride with the timers alone. For running it follows pace targets on a treadmill with a Bluetooth foot pod, or outdoors with GPS; you set the treadmill speed yourself. It pairs Bluetooth heart-rate, power and cadence sensors, and finished workouts go to Intervals.icu or out as a FIT file. Workouts can be edited in a visual editor or in Intervals.icu's text format, and there is a workout library, training load and form, and readiness and sleep. It runs on Android 7.0 or later; iOS is not planned. Made by one developer.
