How many calories can you still eat today? KcalCounter answers in one 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 exactly how much is left. Set a deficit to lose weight, a surplus to bulk, or maintenance to hold steady. ā—† ONE NUMBER, NOT A SPREADSHEET • Your remaining calories are the whole screen. A 12-segment bar shows how much of the day is used. • Tap for the breakdown: BMR, daily activity, digestion (TEF), exercise. • Over budget? You see "over" and the number. No guilt trips. ā—† 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. ā—† YOUR REAL TDEE, NOT A GENERIC ONE • A one-minute lifestyle questionnaire (desk job, standing work, housework, commute) sets your BMR and daily activity from day one. • Sync steps from Apple Health and today's budget rises or falls with how much you actually moved. • Log workouts by activity and duration (MET) or by calories from your watch or machine. See how much they add back. ā—† IT LEARNS FROM YOUR WEIGHT • KcalCounter compares your weight trend with what you logged and corrects the gap between estimated and real burn. Fast metabolism, 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. ā—† A PACE YOU CAN KEEP • Choose lose, gain, or maintain and a weekly pace of 0.25–0.75% of body weight. • The budget has a floor, so an aggressive cut never becomes a crash diet. ā—† 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. ā—† PRIVACY FIRST • No account, no sign-up. Your records live on your device. • Health data stays on the device only. It is never stored in iCloud or used for ads. • Your meals and weight are never used for advertising. ā—† 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 Pick a monthly or yearly subscription, or pay once. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the period, and can be managed or cancelled in your App Store account settings. ā—† MADE FOR YOU IF • 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 the deficit or surplus to be right • 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

Read full description

METs Activity Tracker helps you build a sustainable exercise habit around one simple weekly goal: 10 METs. Just log everyday activities — walking, jogging, climbing stairs, cycling, and more — and the app automatically calculates your progress for the week. No manual math, no complicated tracking. WHY 10 METs? 10 MET-hours a week is a widely used benchmark for a healthy level of physical activity. Regular aerobic exercise supports overall health and may help lower the risk of lifestyle-related disease — some research even suggests it may help reduce cancer risk. BUILT FOR CONSISTENCY Health comes from steady, small effort — not one big push. Log a walk, a jog, or a set of stairs whenever it happens, and watch your weekly ring fill up at your own pace. FEATURES • 15 built-in activities, each shown as "X min = 1 MET" so you never have to calculate anything • Weekly progress ring and daily / weekly / monthly history • Add a forgotten day's record after the fact • Sync completed activities to Apple Health as workouts (optional) • Automatic iCloud backup (optional) • No account required. No ads. No analytics — your data stays on your device. Start today. Your first 10 METs is closer than you think. * This app is designed to support your wellness journey and is not intended for medical diagnosis or treatment.
