Athalyze vs EnduroPace

Athalyze is a training log for athletes who wear more than one device. It runs on iPhone (including iPhone Duo), iPad, Apple Watch and Mac. Run with an Apple Watch and a Garmin, or ride with a bike computer while wearing an Oura ring, and Athalyze merges the recordings into one activity. It works with Apple Watch, Garmin, WHOOP, Oura, Strava, and Google Health devices like Pixel Watch and Fitbit. For each metric it picks the most reliable data, and it keeps the originals so you can see where every number came from. Athalyze is free, with an optional Athalyze Pro subscription for Training Load, Readiness, and deeper analysis. Multi-Device Merging • Recordings of the same workout are combined automatically • Set device priority for each metric if you prefer one source • Compare devices on one chart, each in its own color. Tap a swatch to show or hide it • Import FIT files, including Garmin developer fields like core body temperature • See when a recording switches source, such as heart rate moving from Apple Watch to AirPods Pro • Press play on the map to fly along your route while the charts follow • Two Apple Watches, or a watch and a sleep app like Pillow or AutoSleep, each keep their own heart rate, HRV, sleep and vitals Vitals • Last night's HRV, resting heart rate, respiratory rate, SpO2, skin temperature and sleep on one screen • A Sleep Score for every night, based on how long and how well you slept • Readiness (Pro) gives you a score each morning and suggests how hard to train, using your vitals and your recent training • Choose which device each vital comes from, like HRV from your watch and SpO2 from your ring • HRV is shown as RMSSD, the measure Garmin, Oura and WHOOP use, including Recovery HRV from the newest Apple Watch models.
