Description by Yamada Yuki Written by the developer, not by AppBrain. Click to read.
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.
