OnTrack is a calorie counter, fasting timer, and habit tracker built into one app. Here's everything inside. CALORIE COUNTER Log meals by photo*, barcode*, or search. Calories and macros (protein, carbs, fat) are calculated for you, so logging takes seconds. FASTING TIMER Pick a fasting window (16:8, 18:6, OMAD, or set your own) and start your fast. The timer keeps running in the background and we'll send a notification when your eating window opens. STEP TRACKER Your steps sync from Apple Health automatically. See your daily count and how it stacks against your goal without typing anything. CALORIES BURNED Active calories from your workouts and daily movement pull in from Apple Health. Subtract them from what you ate to see your real net for the day. WEIGHT LOG Track your weight over time and watch the trend. A single morning number doesn't tell you much, but the trend does. PROGRESS PHOTOS Take a weekly photo and watch the change month by month. Each photo is paired with the weight you logged that day so the comparison stays honest. DAILY TO-DOS A short list every morning: log today's weight, start your fast, take this week's progress photo. Small actions, every day, that compound. COMMUNITY Post an update, ask a question, share a recipe, or just lurk. The feed is people working on the same things you are. PERSONALIZED PLAN Answer a few questions about your goals, height, weight, and activity, and we'll set your calorie target and macro split. Adjust any number any time. APPLE HEALTH Steps, weight, workouts, and active calories sync from Apple Health automatically. NOTIFICATIONS Optional reminders to log your meals, end your fast, or check in for the day. Turn any of them off in settings. NOTE: OnTrack is not a medical device and we do not provide medical advice. Recommendations are suggestions only. Talk to a professional and do your own research before making changes to your diet, fasting routine, or training plan. *Photo and barcode food scanning require a subscription. Everything else is free. TERMS: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
