It interviews you, builds a periodised plan from your own training data, checks in every morning and moves sessions when life happens. I built the first version for my own IRONMAN. Now I'm turning it into an iPhone app.
One email when the app is ready to try, nothing else. How we handle your email.
Readiness: lower than usual
From your recent paces. Updated weekly. An estimate, with a range.
Biggest lever: swim. Two technique sessions a week are worth more than extra bike hours right now.
Design preview: an example athlete, not a real person's data. The app is not out yet.
Reads your workouts, heart rate, sleep and HRV from Apple Health, which already collects them from an Apple Watch and from most Garmin, Wahoo and Oura setups.
Periodised plans with base, build, peak and taper, and zones set from your own tests and races, not a generic template.
Tell it you're travelling, sore or short on time, and it rewrites the week. A push each morning tells you what today is.
A finish-time range per discipline that tightens as the data comes in, and says which sport to work on.
I wrote my own AI coach to train for IRONMAN Calella-Barcelona on 4 October 2026. It reads my watch, ring and training log, plans my weeks and predicts my race time. It's a pile of scripts on my laptop. The app is that coach for everyone else, on the phone, with no scripts.
Training guidance, not medical advice. If something hurts, see a professional.
