About

ENDURE is a training and analysis app for smart trainers on iPhone, Android and Windows, with a web app for the coach, planning and analysis; rides are recorded in the apps, which connect to Bluetooth FTMS trainers, power meters and heart rate straps. Each morning an AI coach reads a short check-in, your recent rides and training load and picks today's workout with a lighter and a harder alternative and the reason; on request it drafts the coming weeks in the calendar against weekly TSS targets, and nothing changes there until you apply it. Workouts run in ERG mode, with SIM mode and a free ride by watts; the curated library can be extended with .zwo, .mrc and .erg files, and the AI builds a workout from one sentence. FTP and VO2max are modelled from your rides instead of a test, alongside a power profile, time in zones and TSS. You can log lactate readings during or after a ride to estimate LT1 and LT2, pair a CORE body temperature sensor for live heat zones, and get a climbing score from outdoor rides. A Zwift Click (v1, verified by the developer) changes the ERG target or the resistance from the handlebar, without simulated gears. Rides upload to Strava and intervals.icu and export as .fit. Premium has a 14-day free trial without payment details. Made by Christoph Martin in Austria.
