Most macro apps don't know
you lifted today.
This one does.
Compound Fuel reads HKWorkout from Apple Health and bumps protein and carbs on the days you actually train. Algorithmic targets that back-solve from your weight trend. Built for people who care about plates on the bar, not green checkmarks.
The math that beats a static calculator.
Every feature exists to answer one question: am I eating enough to support the work? Everything else got cut.
Targets that adapt to what your body actually does.
No more "1.55 × BMR forever." Each week, Compound Fuel re-solves your TDEE from your weight trend and logged intake. If you gained when you should've lost, the next week's targets adjust. The math keeps up — you don't have to.
- Weekly back-solve from real intake, not guesswork
- Split TDEE for training days vs rest days
- One-tap accept on the suggested adjustment
The day you squat 315 isn't the same as a rest day.
Compound Fuel reads HKWorkout from Apple Health — written by Compound Theory, your Watch, or any lifting app — and auto-bumps protein and carbs on training days. No manual toggle. The app sees the workout and the day's targets shift.
- Detects strength workouts from Apple Health automatically
- Bumps protein +0.4g/lb and carbs proportional to volume
- Per-day overrides for refeeds and deload weeks

Rest day. Lift day.
Same person. Different math.
Most apps give you one number forever. Compound Fuel sees that you squatted, and shifts the day. Here's what that looks like.
Sunday
No workout · maintenance + recovery
+5×3@315
Tuesday
Lower body · 14,250 lb total volume
Reads work. Writes intake.
Most apps treat Apple Health as a one-way export. Compound Fuel reads workouts and weight in, then writes every dietary sample back out — so the Health app, your doctor's visualizer, and any other app you use see the full picture.
Coming from MyFitnessPal, Lose It, or Cronometer? Settings → Import → All time. Compound Fuel pulls every dietary sample they ever wrote — up to 10 years back — and rebuilds your log from day one. Including your streak.
