Endyr synthesizes the data your athletes are already collecting — wearables, training, sleep, fuel, body composition — into intelligence a coach can act on. It doesn't replace coaches. It amplifies them.
Launching with a small group of coaches and competitive athletes. Built for CrossFit, Hyrox and functional fitness.
Thirty days of green in a row and your HRV has been climbing for two weeks straight — your body is telling us something good. Sleep was a little short last night, but it hasn't dented your readiness.
Physiology, history, sleep and lifestyle shape how each body turns training stress into fitness. A template can't see any of that. Endyr learns every athlete — how fast they recover from heavy days, how much load they can truly absorb, what makes them adapt — and tunes every recommendation toward the result they're chasing: fitter, stronger, faster, leaner. The longer it works with an athlete, the sharper the fit.
Recovery in one app. Sleep in another. Training in a spreadsheet or a coaching platform, nutrition in a fourth app — if it's logged at all. The signal a coach actually needs is buried across all of them, and there's no time in the day to dig it out for one athlete, let alone a full roster.
Data without experience is sometimes worse than no data at all — you make confident decisions based on incomplete signals. Endyr exists to close that gap.
Every morning, Endyr reads the night's recovery, sleep and strain in context of the last weeks of training — then tells the athlete how to approach the day in plain language. Not a score. A read, with a recommendation.
When recovery is down, prescribed loads are adjusted automatically — with the reasoning shown, the coach's intent protected, and the original prescription always available. The athlete chooses; the coach stays in charge.
Endyr watches training load ratios, recovery trends, sleep debt and under-fueling signals continuously. When patterns stack up, the coach is notified first — with what was noticed and what to do about it today.
"How am I trending this week?" "Why was my session adjusted?" "What's my Fran PR?" Endyr answers from the athlete's full context — every metric, every session, every meal it has seen.
Wearables, sleep systems and nutrition apps connect in minutes. Historical data is imported so the intelligence starts with a baseline, not a blank page.
"Power cleans 4x185, 3x205, 2x225 — felt strong." Endyr parses it, tracks the movements, computes the maxes and spots the PR. Meals log from a photo.
Athletes get a morning read and sessions tuned to their readiness. Coaches get a squad view that says who's ready, who's accumulating fatigue, and who needs a conversation today.
All providers are normalised into one picture — and when an athlete wears more than one device, Endyr synthesizes them instead of making you pick.
Your athletes' health data is used to coach them. That's it.
Endyr does not use athlete health data to train general-purpose models that are shared with or sold to anyone.
One team's data is never visible to another team, its coaches, or its members. Affiliates compete — their data doesn't leak.
Full structured export delivered within 72 hours. Deletion with a 7-day safety window, completed across all systems within 30 days.
Photos are analysed in real time and immediately discarded. No image ever sits on a server.
An athlete's journal is read by their AI for pattern detection only — coaches need separate, explicit permission for every entry.
Endyr is launching with a deliberately small group — coaches and competitive athletes who want to shape the product, not just use it.
