Features
Everything you need to climb.
Honest data and real coaching for lifting and cardio alike — built for the serious gym-goer who wants signal, not vanity metrics.
Logging
Log a set in seconds
Reps, weight, and effort — that is all it takes. Sets group into workouts automatically, and Peak Fettle estimates your 1RM from every working set so progress is visible immediately.
- Auto-grouped workouts
- Estimated 1RM per set
- RIR / effort tracking
Strength score
One honest number, 0–1000
Your score blends estimated 1RM with volume, progressive overload, and consistency. Beginners feel fast early momentum; advanced athletes get an honest, asymptotic curve. Prefer the classics? Switch to DOTS or Wilks any time.
- Peak Fettle score or DOTS / Wilks
- Rewards consistency, not just genetics
- 8-week trend at a glance
Percentiles
Ranked against people like you
Percentiles are cohort-matched by sex (with a unisex opt-out), age, and years trained — recognizing that relative gains slow as you advance. Encouraging at the start, honest for the long haul.
- Matched cohorts, never veterans vs. beginners
- Unisex scale on request
- Per-lift and overall
Consistency
Streaks that survive real life
Showing up is the baseline — even a five-minute visit counts. Miss a day and a make-up window keeps your streak honest; an emergency override covers exams, illness, and travel without shame.
- Make-up window each week
- Emergency override
- Lost only after two unmanaged misses
