You spend 6 hours a week under a barbell. You track every set, every rep, every progressive overload. But when it comes to food, you're estimating. And that's why you're stuck. That isn't a discipline problem. You have plenty of discipline. It's a measurement problem — the gym half of your training is logged to the gram, and the kitchen half is a guess. GainCut closes that gap. PHOTO-FIRST MACRO TRACKING Point your camera at your plate. GainCut identifies the food, works out the portion, and logs the macros. No food database to scroll, no barcode to hunt, no entering every ingredient by hand. Trained on real portions — including HK and Chinese staples like char siu, rice, noodles and dim sum — because those are the meals that actually break generic trackers. RECOVERY, NOT JUST CALORIES Training load is only half the picture. GainCut reads your heart-rate variability, resting heart rate, and sleep from Apple Health, then turns them into a plain-language readiness score. You get told what the number means for today's session — push, maintain, or back off. No dashboard to interpret, no guessing whether you're recovered or just motivated. THE SEVEN DAYS THAT COUNT One good day proves nothing, and neither does one bad one. Your macros move your body over a week, not in 24 hours — so GainCut scores you on a rolling seven-day window. It also separates the two things most apps blur together: • Where your body is actually heading — measured against your real, measured burn, not a formula. • How closely you hit your own target, day to day. Those can point in opposite directions, and both can be true at once. A week that looks flat on the scale can still be the week you nailed your plan. GainCut shows you which one you're in — including on maintenance, where the goal is to stay, not to cut. BUILT FOR PEOPLE WHO TRAIN • Set your own surplus or deficit — 0 to 1,000 kcal, not a fixed default. • HealthKit-synced weight and body-fat trends, so progress is measured, not felt. • A food database tuned for real, cooked, restaurant and home-cooked meals. • Fast manual logging for the days you already know what you ate. If you're exact in the gym and approximate in the kitchen, that gap is the whole problem. GainCut is the other half of your training log. Track what you lift. Track what you eat. Stay in the green.
