Maintain Calorie

Is the number from an online calculator really *your* number? Maintain Calorie reverse-calculates your maintenance level from your own weight and intake data. Observation, not assumption. A value derived from your data, for you. ■ How it works The app applies linear regression to the past 14 days of body weight to derive a daily change rate (kg/day), then combines it with your average intake: Maintenance kcal = Average intake − Weight change rate × Energy coefficient (7700 or 7200 kcal/kg) If you're losing weight, the result will be higher than your average intake — confirming your real burn is greater than what you ate. ■ HealthKit, minimal input Maintain Calorie pulls 14 days of body weight and dietary energy from HealthKit automatically. Bring in the data you already log in another app. ■ Who it's for • People setting calorie targets for a cut or bulk • Anyone who wants their maintenance level derived from real data • Calculation-minded users who want a transparent formula ■ Philosophy This is not a daily food-logging app. It is a tool that observes your data to estimate a personal constant — your maintenance calorie level. ■ Privacy All calculations happen on-device. Your health data is never sent anywhere. ■ Note This is an estimate. Not intended for medical use.
