Deficit Streak vs Maintain Calorie

LOSE WEIGHT BY WINNING EVERY DAY Most diet apps drown you in food databases and decimal points. Deficit Streak does one thing — and does it better than anything else: it keeps you in your calorie deficit, day after day, until the results show up. Set your target. Check in once a day. Watch your streak grow. That's the whole game — and it's the only thing that actually moves the scale. BUILD A STREAK YOU WON'T WANT TO BREAK One tap a day: hit your deficit, miss it, or take a rest day. Your streak grows with every win and becomes the daily motivation that keeps you consistent when willpower runs low. Earn streak freeze tokens to protect your progress on tough days.

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.
