Start the day knowing.
Three signals, read together every morning, so you never have to guess which one to fix.
Fuel
Calories and macros against a target that moves with your training day, and a nudge when you fall short.
Train
Sessions, sets and load. Your plan reads recovery before it decides how hard today should be.
Coach
An AI with your full file open.
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.
- Answers grounded in your last 30 days
- A morning brief, before your first coffee
- Specific numbers, never a wellness essay
- It will tell you to rest, too
And that’s not all.
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. Search our own catalogue of 14,000+ foods. Or say what you ate and AI estimates the macros for you to check, three times a day on the free plan.
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.
