About
Built for the long climb.
Peak Fettle started from a simple, stubborn belief about fitness — and a frustration with apps that flatter, shame, or overwhelm.
Most people don't quit training because a program was wrong. They quit because it was unsustainable — too aggressive, too rigid, or too discouraging.
Peak Fettle is built around the most reliable finding in fitness: consistency is the most critical factor in progress. So we measure it, protect it, and reward it. A five-minute visit still counts. A missed day has a make-up window. A beginner is never ranked against a ten-year veteran.
We serve every discipline — weightlifting, running, cycling, swimming, team sports — with tools that are both deeply personal and quietly competitive. A 0–1000 strength score and an estimated 1RM for lifters. Splits, pace, and consistency for cardio. And, for those who want it, an AI coach that writes a plan around your real life and adapts it to the performance you actually log.
No vanity metrics. No dark patterns. Just an honest picture of where you are, where you rank among people like you, and a sustainable way to climb.
What we stand for
Four principles, no compromises.
Consistency over intensity
The session you keep beats the session you skip. We design every feature to make showing up easy and shame-free.
Honest by default
Cohort-matched percentiles and an asymptotic score that tells the truth — encouraging early, realistic for the long haul.
Your plan, your call
AI suggests; you decide. Swap exercises, shift days, change goals. Enjoyable plans are the ones people actually follow.
Your data is yours
No ads. No selling your training history. Clear about what we store and why — and easy to take with you.
