Ask anything

A coach in your pocket, 24/7

Ask for a meal swap, a harder leg day, or why the scale stalled. The coach already has your goals, diet, streak, and calories in context — so the answer actually fits you.

Plan & fuel

A plan that adapts, macros that add up

Get an AI-personalised week, then log meals in a tap. Scan a plate to capture calories and macros, keep hydration on track, and let the plan adjust as you go.

Progress you can actually see

Every week, FormFuel sums your active days, exercises, calories burned, and best activity — so the work shows up in numbers, not just in how you feel.

Weekly reportBest activityTrends
Know your numbers

Body stats, backed by the science

See your BMI, body-fat estimate, and TDEE — with cut, maintain, and bulk calorie targets. Every figure cites its formula and source, and is clearly marked as an estimate, not medical advice.

Beyond the workout

Made for every body

Track your menstrual cycle — current day, next-period forecast, and average length — and document your transformation with a private progress-photo timeline.

Progress photos, kept private

Snap a photo any day — front, side, back — and FormFuel saves it to your own private timeline. Stored in a private bucket scoped to your account only, never public, only ever shared if you choose to.
