AI fitness tracking apps: what they are and who makes them
run and ride analysis platforms, strength loggers, guided class and coaching apps, indoor cycling and activity video: Strava, intervals.icu, Tredict through Relive.
Types of AI fitness tracking apps
Run and ride analysis platforms
Strava, intervals.icu, RUNALYZE and Tredict collect activities from watches and bike computers, then chart fitness and fatigue. Three of them let you point your own AI assistant at your data through an MCP connector rather than shipping a built-in coach.
Strength loggers
Hevy, Strong and JEFIT record sets, reps and routines. Hevy and Strong are plain logbooks with paid analytics, while JEFIT names an AI Workout Tracker and Adaptive Plan on its home page, though the pages place neither feature under a specific plan, so check before paying.
Guided class and coaching apps
Peloton App, Apple Fitness+ and Freeletics deliver instructed sessions or plans. Peloton names its AI-powered Peloton IQ and Freeletics calls itself an AI Coach, while Apple describes its For You and Custom Plans personalization without using the term AI, so it only counts as guided here.
Indoor cycling and activity video
Zwift turns a smart trainer into a virtual world with workouts and a Plus coach, and Relive turns finished activities into shareable 3D videos. Neither names an AI feature on the pages we read, so they sit at the foot of an AI-focused list.
