FuelKey

Stop guessing. Start fueling. FuelKey works out what your body actually needs, builds a plan from real meals, and turns every day into a checklist instead of a math problem. REAL TARGETS FOR YOUR BODY Answer a few questions about your height, weight, age, how you train and what you're after. FuelKey turns it into a daily calorie and protein target, then builds meals that hit both. YOUR DAY IS A CHECKLIST Tap once for eaten, twice for skipped. Ate the whole plan? One tap checks off the rest. Totals update as you go, a skipped side never makes a whole meal look failed, and a forgiving streak counts the days you finish. SNAP THE PLATE Eating out? Take a photo, name the place if you know it, and FuelKey breaks the plate into parts you can adjust in a tap. Ate it instead of your planned lunch? One switch keeps your day complete. ON THE ROAD Stuck with fast food or a gas station? Say where you are and get specific orders that fit what's left of your day, sized for the meal and heavy on protein. SEARCH, SCAN OR DESCRIBE Search verified foods with real portions, scan a barcode, or describe a meal in your own words and get an estimate in seconds. Adding something off-plan shows right away whether it fits. A WEEKLY REVIEW THAT LEARNS YOUR BODY Once a week, on the day you pick, FuelKey measures your real burn from your logs and your weight trend, then suggests a change as real food swaps: small when you're close, a bigger first step when your numbers show the plan is far off. You approve every change. It only learns from days you finished, so a forgotten dinner can't trick it into cutting your food. YOUR WORKOUTS COUNT Turn on workouts from Apple Health and a recorded run, ride or lift raises that day's target, with the extra food added as a one-tap add-on. Trying to lose weight? Your target stays put by default so the burn adds to your deficit, and eating it back is one switch. SMART SCALE OR TYPE IT Weigh-ins from your Wi-Fi or Bluetooth scale arrive through Apple Health on their own. FuelKey keeps your morning and before-bed weights and never replaces a weight you typed. SEE HOW YOU'RE DOING Your weight trend under the daily noise, calories against target, and how closely you followed the plan over the last two weeks. New users get a short guide to what changes in weeks 1 to 6. COOK FROM WHAT YOU HAVE Tap the foods already in your kitchen or scan them, and they stay off your shopping list. Build a plan from your pantry, or from the stores you shop at, and your list splits by store. IMPORT ANY RECIPE Paste a recipe link, paste the recipe itself, or snap a photo of a recipe card. FuelKey reads the ingredients and works out the numbers per serving. You check it before it's saved. THE GROCERY LIST WRITES ITSELF Your plan times the days you're shopping for, grouped by aisle and counted in packages. Add prices to see your cart total and which foods give you the cheapest protein. APPLE WATCH Check off a meal, see what's left for the day, and log your morning weight with the Digital Crown.
