Weight, body fat, steps — see your Health data in one clean chart. The app reads what is already recorded in the Health app and draws it as a smooth, interactive chart. With Home Screen and Lock Screen widgets and an Apple Watch app, your progress is always a glance away — no need to open the app. WHAT YOU CAN TRACK Eight metrics: weight, body fat percentage, lean body mass, BMI, waist circumference, steps, active energy and dietary energy. Show only the ones you care about — the app asks Health for permission to read just those. FEATURES - Automatic Health sync Your data flows in from the Health app. No manual entry: any scale, tracker or food app that writes to Apple Health works right away. - An interactive trend chart View 1 week, 1 month, 3 months, 6 months or 1 year. Scroll sideways to explore your full history. Metrics that accumulate through the day, like steps and calories, are shown as daily totals in a bar chart. - 7-day moving average Cut through daily fluctuations and see your true trend. The moving average line can be toggled on or off at any time. - Period stats that follow your scroll As you move through the chart, the average and the total change for the visible window update in real time. - Home Screen and Lock Screen widgets Three Home Screen sizes (small, medium, large) plus rectangular, circular and inline Lock Screen widgets. Each widget can be set to its own metric and time period. Lock Screen widgets can also show units if you like. - Apple Watch app See charts for the past week or month and your latest value right on your wrist, and switch metrics on the watch. Complications and the Smart Stack are supported too, with the metric of your choice for each widget. - Themes Pick from 30+ themes, in light and dark variants, to recolour the whole app, your widgets and Apple Watch at once. Prefer no theme? Choose from 20 chart colours instead. - Available in 8 languages English, Japanese, Simplified Chinese, Traditional Chinese, Korean, German, Spanish and French. Follows your system language, or set one inside the app. ABOUT PRO - Dual-axis chart Overlay two metrics on one chart — weight against steps, for example — in the app, in your widgets and on Apple Watch. - All themes Use all 30+ themes, not just the 4 free ones. - No ads Pro comes as a monthly plan (auto-renewing), a yearly plan (auto-renewing), or a one-time purchase that never expires. Prices are shown on the purchase screen in the app. Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period. Payment is charged to your Apple Account at confirmation of purchase, and renewals are charged within 24 hours before the period ends. You can cancel at any time in Settings > Apple Account > Subscriptions. Terms of Use: https://aucfan-suguru-yamada.github.io/weight-widget/terms Privacy Policy: https://aucfan-suguru-yamada.github.io/weight-widget/privacy-policy PRIVACY The app reads only the metrics you choose to display, and never writes to the Health app. Your Health data stays on your iPhone and Apple Watch and is never sent to any server. No account is required. To improve the app, we use Google Analytics for Firebase to understand how it is used (for example, which screens and features are opened). This never includes your Health data. The free version may use an advertising identifier (IDFA) to show relevant ads. Health data is never used for advertising. Make tracking your body simple enough to actually keep up with.

Diet Otter turns a simple weigh-in into a real reading of your progress. You log your weight. The app does the rest: it works out your body fat percentage, your basal metabolic rate, your daily energy expenditure, and draws the actual trend of your curve — the one that matters, not the day-to-day noise. TRACK WITHOUT THE CHORE • A weight, a date, that's it • Calorie and protein counters, two taps • Waist, neck and hip measurements if you want more precision • A logbook of every day you've recorded UNDERSTAND WHAT IT MEANS • Body fat percentage using the Navy method, as used by the US Navy • Lean mass, basal metabolic rate (Mifflin-St Jeor), estimated total expenditure • Average and cumulative calorie deficit, converted into theoretical kilos of fat • Charts for weight, body fat and calories KNOW WHERE YOU'RE HEADING • Curve projection by linear regression on your own data • Estimates at 7 days, 1 month, 3 months, and up to next Christmas • Estimated date to reach your target weight YOUR DATA STAYS YOURS • No email, no phone number: a nickname and a 6-digit PIN are enough • No health data is ever used for advertising • Permanently delete your account from inside the app, in two taps • French, English and Japanese Diet Otter is free. It is funded by a few ads, shown sparingly. — Diet Otter is a personal tracking tool. The values shown are rough estimates, for guidance only: they are not a diagnosis, medical advice or treatment. Please consult a health professional before starting any weight loss or weight gain plan.
