ダイペットは、あなたのお腹からとれた“ぜい肉”を食べて育ちます。 ダイエットによって減った分の体重が、ぜい肉としてペットのエサになります。 あなたがダイエットに成功すればするほどペットが成長します。 飼育期間(ダイエット期間)は30日、60日、90日間で選択ができます。 目安ですので期間を過ぎても継続できます。 ※本アプリは、2012年8月にリリースされたダイペットの強化版です。データの引継ぎはできませんので予めご了承ください。 ※期間中の最低体重がベースとなる為、最低体重より減った場合のみ「ぜい肉」が与えられます。期間中に増えた体重分が減っても「ぜい肉」は与えられず「0g」と表記されます。 計測可能体重は30kg~200kg、目標体重の差は2kg以上が必要です。

How many calories do you have left today? KcalCounter answers with a single number. Log what you eat. KcalCounter builds your daily calorie budget from your BMR, everyday activity like commuting and housework, the energy you burn digesting food, and your workouts, then shows how much is left. Run a deficit to lose weight, a surplus to bulk, or eat at maintenance to hold steady. ◆ ONE NUMBER, NOT A SPREADSHEET • Your remaining calories, front and center. A 12-segment bar shows how much of today's budget you've used. • Tap for the breakdown: BMR, daily activity, digestion (TEF), exercise. • Over budget? You see "over" and the number. No guilt trips. ◆ LOG A MEAL IN ONE TAP • Recent and Frequent lists bring back the meals you eat every week. • Templates bundle several items ("usual breakfast," "post-workout") into a single tap. • Names are optional. Calories are enough. No barcodes, no macro entry, no food database to wade through. ◆ YOUR REAL TDEE, NOT A GENERIC ONE • A one-minute lifestyle questionnaire (desk job, standing work, housework, commute) estimates your daily activity from day one. • Sync steps from Apple Health, and your budget rises or falls with how much you actually move each day. • Workouts recorded in Apple Health are added automatically. You can also log one by activity and duration (MET) or by the calories your watch or machine shows, and see how much it adds to your budget. ◆ IT LEARNS FROM YOUR WEIGHT • KcalCounter compares your weight trend with what you logged and corrects the gap between estimated and real burn. Fast or slow metabolism, it adapts either way. • Accuracy is shown honestly: "Learning 12/28 days," then "±150 kcal." • Weight is tracked as a trend, so water weight and a salty dinner don't throw you off. ◆ A PACE YOU CAN KEEP • Choose to lose, gain, or maintain, then pick a weekly pace (0.25–0.75% of body weight when losing). • The budget has a floor, so an aggressive cut never becomes a crash diet. ◆ BUILT FOR CONSISTENCY • Meal and weigh-in reminders that stay quiet on days you've already logged. • A weekly summary to review last week's balance and weight. • Progress tab: days on target, calorie balance, weight trend, and estimated burn over 7 or 30 days. • One clean design across inputs, buttons, and charts. Dark Mode included. ◆ PRIVACY FIRST • No account, no sign-up. Your records stay on your device, or in your own iCloud if you turn on sync. • Health data never leaves your device. It isn't synced to iCloud or used for ads. • Your meals and weight are never used for advertising. ◆ KCALCOUNTER PRO (OPTIONAL) Logging, the budget, learning, step sync, reminders, and templates are free. Pro adds: • No ads • 90-day, 1-year, and all-time progress, plus weight forecasts • iCloud sync to carry everything to a new phone • CSV export • Six accent colors • Home Screen and Lock Screen widgets that always show what's left Choose a monthly or yearly subscription, or a one-time purchase. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period, and can be managed or canceled in your App Store account settings. ◆ WHO IT'S FOR • You've quit calorie-counting apps before because they asked for too much • You want calories and weight, not a nutrition lecture • You move a lot at work or at home and want that to count • You're cutting or bulking and want your deficit or surplus dialed in • You'd rather see numbers than pep talks Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://yssdev.com/privacy/kcalcounter
