Expert nutrition science for young athletes
In your hands, on your terms.
One number.
Your whole fuel game.
The F-Charge Score is a proprietary 0–100 read on how well you're fueling for your sport — weighted by your goal, not a generic calorie target. Five sub-scores roll into one chrome number you actually want to beat.
Five reads. One score.
Your goal changes the weighting. Performance, body composition, or weight gain — the score knows the difference, so it always reflects your mission.
Built to win the fueling game.
The score that ranks your fueling
A 0–100 composite of five sub-scores, weighted by your goal — performance, body comp, or weight gain. Not a calorie tracker. A performance metric you compete on.

Snap your plate, ask what to eat before a 4 PM match — your AI coach answers with the why behind every call. It knows your schedule, your position, your goals.
Plans assigned by your trainer

Fuel and fluid, dialed together
Hydration and micronutrients tracked alongside your macros — because being charged isn't just calories. Stay topped off for the second half.
