Compound Fuel: Nutrition

Macros built for lifters

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Snap a meal, review AI-estimated foods and macros, then log it. Built for lifters with training-aware targets, adaptive TDEE, and fast food search. Compound Fuel is a nutrition tracker built for lifters. It knows you squatted 315×5 today, because it reads your training from Apple Health — and it scales your protein and carb targets on the days you actually lifted. TRAINING-AWARE TARGETS Most nutrition apps treat every day the same. Compound Fuel doesn't. Heavy deadlift day? Protein bump, carb bump. Rest day? Targets shift accordingly. The app reads your workouts from Apple Health — whether you log them with Compound Theory, Apple Watch, or any other HealthKit-connected app — and adjusts accordingly. ALGORITHMIC TDEE No static "1.55 × BMR forever." Compound Fuel back-solves your true energy expenditure from your weight trend and actual intake, then updates weekly. Your targets converge on what your body is actually doing, not a textbook guess. FAST LOGGING Search, barcode scan, quick-add, recent foods, reusable meal templates, and a food library you build once and reuse. The log screen is the first tab for a reason — get in, log the meal, get out. AI MEAL PHOTO ESTIMATES — PRO Photograph a meal or choose an existing photo. Compound Fuel suggests likely foods, estimates portions and macros, and matches results against the food database when possible. Review every item, change food matches or grams, enter macros manually when nothing matches, and approve the final log yourself. AI estimates can be inaccurate and are never logged without your confirmation. HEALTHKIT-NATIVE Compound Fuel writes dietary protein, carbs, fat, and energy directly to Apple Health. Your intake lives in the system of record, not a proprietary vault you lose when you switch apps. Other apps can read your data. You own it. PROGRESS YOU CAN SEE Weight trend with smoothing. Macro history. A TDEE trace that shows you how your metabolism has drifted over weeks. Nothing hidden behind a paywall you can't even preview. NO CALORIE-SHAMING Targets are information, not a judgment. Over-budget days happen. The app tells you what happened — it doesn't guilt you. iCLOUD SYNC Your food log lives on every device signed into your iCloud account. iPhone, iPad, new phone — your history comes with you. SYNCS WITH COMPOUND THEORY Compound Fuel pairs natively with Compound Theory, our strength training app. Workouts you log in Compound Theory write to Apple Health as HKWorkout samples — Compound Fuel reads them and bumps your macros for the day automatically. Your dietary intake flows back through Apple Health, so Compound Theory can see your fueling without either app touching the other directly. Two apps, one Apple Health source of truth, no proprietary lock-in. BUILT BY A LIFTER, FOR LIFTERS Compound Fuel works great on its own — but it's at its best when paired with Compound Theory. If you lift and you want nutrition that reflects that, this is for you.
