Outlier turns your fitness into an RPG. Track workouts, measure your body, and see exactly where you rank on a Gaussian distribution — your real percentile among real people.
Outlier treats your body like a character sheet. Every measurement and every session counts toward your rank.
Enter your body stats — weight, height, circumferences, body fat. Outlier calculates your real percentile using NHANES population data and a Gaussian model.
Log workouts in Quick or Live mode. Choose from 10 presets or build your own. 89 animated exercise guides keep your form sharp.
Your level reflects where you actually stand — not just how many times you opened the app. Watch your percentile climb as your body changes.
Track progressive overload, earn achievements, keep your streak alive. The cat starves if you don't train. Don't let the cat starve.
Everything you need to track, analyse, and level up — no subscriptions, no ads, no fluff.
Gaussian distribution based on NHANES population data. See where you actually stand, not where an algorithm wants you to feel good.
Per-set logging with rest timer, pause/resume, undo sets, extend cooldown, and sound feedback per theme. Runs over navigation — won't reset.
Every exercise has a smooth animation guide. Search by category, add mid-workout, merge whole templates on the fly.
Automatic PR detection across your session history. Badges per theme — ↑ PR / > UPGRADED / >> IMPROVED.
Navy body fat formula with floor clamp, percentile chart, goal line, history and tooltips. Estimates flagged with ≈ for transparency.
Level, top percentile and streak at a glance. Updates after every workout finish.
Daily streak, 10 easter eggs, achievement system, quests and a cat that gets hungry when you skip training.
All data stays on your device by default. Optional Google sign-in for cloud backup — you own your data, always.
Pick the aesthetic that fits your headspace. Every screen, sound, and badge changes with it.
