03 — The App
A coach
in your
pocket.
Marginal Gains Coach is our iOS app. It plans your training, watches your recovery, and adjusts the week before you have to ask. Quietly, in the background — built for the triathletes, ultra-runners, and bikepackers whose calendars don't look like everyone else's.

Features
What it actually does.
Adaptive Training
Your plan rewrites itself when life happens. Miss a session, do an extra one, sleep four hours — the next week adapts to what your body actually did.
Lab-Grade Metrics
Threshold, VO₂ proxy, durability score. The same numbers we calculate in the studio, computed continuously from your rides and runs.
Recovery & Readiness
HRV, sleep, training load. A daily readiness score actually built on a model — not three arbitrary inputs and a wellness emoji.
Built for the Long Stuff
Multi-day bikepacking, Ironman blocks, ultra-trail tapers. Most apps forget what training for a 24-hour event looks like.
TestFlight Beta
Coming to iOS in
2026.
We're onboarding a small beta in batches. Drop your email and we'll send a TestFlight invite when the next slot opens.
