About

Calorie counting doesn't have to mean scanning barcodes and searching food databases. One Count gives you one number for your day and tells you clearly how much you have left. ONE NUMBER FOR YOUR WHOLE DAY Tap + when you eat and − when you work out. Everything goes into the same live balance, so there's nothing to add up. TAP TO LOG, HOLD FOR DETAIL Need more than a quick tap? Hold + or − to type an exact amount, and add a meal name and protein, carbs and fat if you want them. Fix mistakes or add details later in Today's Log. KNOW EXACTLY WHERE YOU STAND - Green means you're on track. - See how many calories you have left today. - Gone over? One Count shows exactly how many calories to burn to get back on target. IT BURNS CALORIES WHILE YOU DO A quick setup works out your daily burn from your age, height, weight and activity level. Your balance goes down through the day, just like your body, so it's always up to date. ON YOUR LOCK SCREEN, APPLE WATCH AND HOME SCREEN - The Live Activity shows your balance and calories left on your Lock Screen and Apple Watch. - Widgets show calories left today and let you log with + and − without opening the app. - Add Log Food and Log Exercise buttons to Control Center. - Ask Siri: "Log calories in One Count" or "How many calories do I have left in One Count". WORKS WITH APPLE HEALTH Turn on Apple Health sync to: - subtract your workouts and active calories automatically - keep your daily burn accurate as your weight changes - save the food you log to Health Your Health data stays on your device. WORKS FOR ANY GOAL - Lose weight: set a daily deficit. - Gain weight or bulk: set a daily surplus. - Maintain: keep your target at zero. HISTORY THAT KEEPS YOU MOTIVATED Each day is saved when it ends. See which days you hit your goal, tap any day to see what you logged and your macros, and follow your week and month. SIMPLE BY DESIGN No food database. No account to create. Just one clear number and a goal. One Count is free with ads. You can remove them with a one-time purchase. One Count is a general wellness tool and does not give medical advice. Talk to a healthcare professional before starting a diet or exercise plan.
