Intervals.icu Companion: Master Your Fitness, Fatigue, and Form

Intervals Companion is a third-party app that uses the Intervals.icu data API. It is not a full replacement for https://intervals.icu, but rather a companion app focused on delivering insights into fitness, fatigue, and form through configurable desktop and home screen widgets, as well as Apple Watch faces.
