Understand the calories you burn, log food and see how your everyday choices add up. Calorimeter brings your calorie burn, nutrition and progress together with Apple Health, helping you find a routine that works for you. See the full picture of your daily burn, from resting energy to movement and workouts. Get a personal estimate of how many calories you’ll burn by the end of the day, so you can plan ahead with more confidence. Keep a food diary that fits your day. Search foods, scan barcodes and choose your portions, or add calories and macros directly when you want to keep things simple. Favourites, recent foods and saved recipes make familiar meals quicker to log, with nutrition calculated per serving. Follow protein, carbohydrates and fat alongside your calories and remaining daily allowance. Choose your own targets or calculate goals using your burn history and established formulas, including Mifflin-St Jeor, revised Harris-Benedict and Katch-McArdle. Understand your energy balance by comparing the calories you consume with the calories you burn. See your estimated deficit or surplus, explore weekly, monthly and yearly trends, and follow changes in your nutrition, weight and workouts. Revisit past days in your diary to discover what’s working for you. Keep your progress close with Home Screen and Lock Screen widgets, or check your daily summaries, logged foods and workouts on Apple Watch. Ask Siri for today’s burned calories or remaining allowance. For a little extra motivation, all-time widgets give you a fun perspective on the energy you’ve burned or consumed along the way. With colour themes to make it your own, Calorimeter helps you build a clearer picture of your habits, one day at a time.
