Recovery, nutrition, and training read together, so you know whether to push, maintain, or recover.
Sleep duration, regularity, recovery, and your morning check-in, read together. Recovery and HRV sync from WHOOP.

Calories, protein, macros, and hydration against a target that adapts to your day.

Your plan, recent training load, and today’s recovery decide how hard to train.

Not a chatbot you re-explain yourself to. Coach already knows your recovery, your last meal, your training load and your sleep debt, so the answer to “should I lift today?” is actually useful.

Log water in one tap. Fuel sets a target from your body weight and the day’s training, then nudges you when you fall behind.
Track what you actually take, with dosages, so your stack sits alongside the rest of your day instead of in a separate app.
Scan a barcode and Fuel looks it up in Open Food Facts, or search our own food catalogue. Or say what you ate, photograph the plate, or shoot the nutrition label, and AI estimates the macros for you to check. The free plan gives you three AI estimates a day across voice and label together, one photo estimate a day on top of that, and three barcode scans; catalogue search, manual entry, saved meals and copying a day are unlimited.
Thirty seconds each morning on sleep, mood, stress and soreness. It teaches the score what actually moves your recovery.
Recurring weekly splits with real progression. Reorder days by dragging, and the plan re-reads your recovery before it prescribes.
Fourteen days at a glance, and every logged day kept. Your trend is the point, not any single number.
Your health data is encrypted in transit and at rest, never sold, and never shared with data brokers or advertisers. Coach runs on Google’s Gemini: your question goes with a summary of your recent logs and wearable metrics, and — where the safety screen applies — the risk category it flagged. Your journal text never does. Delete your account in the app and every record we hold goes with it, in one operation.
