An AI coach that actually knows your training.

Fathom tracks your workouts, weigh-ins, and nutrition, then grounds an AI coach in that real data — not guesses — to help you train smarter and stay consistent.

No spam — one email when Fathom opens up on the App Store.

Built on what you actually do, not what you say you'll do.

Every part of Fathom feeds the same source of truth — your logged sets, your weigh-ins, your streak — so the coaching, the charts, and the game layer all agree with each other.

A coach that's read your logs

Ask why your weight plateaued, whether you're ready to add weight to a lift, or how this month compares to last. Fathom answers from your real training history, not a generic script.

Log every set without the friction

Track weight, reps, and sets against a target range, swap an exercise mid-workout, and let a rest timer tell you — with sound and a vibration — exactly when to go again.

See the trend, not the noise

Body weight swings by kilos a day for reasons that have nothing to do with progress. Fathom smooths every weigh-in into a real trend line, so you know if you're actually on track.

The Depths: training becomes a climb

Earn Pearls for logged workouts and PRs, keep a streak alive, and rise through five tiers — from Warm-Up to PR Territory — on a weekly leaderboard against people training right alongside you.
