Logging food shouldn't take longer than eating it. Zero Cal gives you four quick ways to add a meal: • Describe what you ate in your own words • Take a photo and let AI estimate what's on the plate • Scan a barcode or nutrition label • Search more than four million foods See the whole day The calorie ring shows how much you have left. Protein, carbohydrate, and fat stay beside it, so you can check the numbers without digging through charts. Leave room for real life Your daily goal fills three quarters of the ring. The last quarter is a visible cushion for a bigger dinner or an unplanned snack. You can repeat recent meals, change portions, and follow your progress over 14 days. Ask Zero When you want more context, ask for a short AI read on food quality, processing, fullness, and possible blood sugar impact. Stay consistent A logging streak and calendar show which days you tracked. On weekends, a short report sums up the week: completed days, average calories and macros, and a couple of suggestions based on your logs. What you can do • Log by voice, text, photo, barcode, or label • Get calorie and macro estimates • Edit portions and ingredients • Set personal calorie and macro goals • Search foods, review history, and add past meals again • See your logging streak on a calendar • Get a weekend report on completed days, calories, and macros • Turn on logging reminders and weekly report notifications • Use the app in English, Spanish, or Russian • Choose a light or dark theme Zero Cal tracks nutrition. It does not give medical advice. Estimates can differ from the actual food, so check the label or another reliable source when accuracy matters. Zero Cal requires a subscription. Payment is charged to your App Store account. Subscriptions renew automatically unless you cancel at least 24 hours before the current period ends. You can change or cancel your subscription in your App Store account settings. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

ЧУЗИ помогает вести дневник питания: добавляйте еду вручную, по фото, штрихкоду или текстовому описанию. Проверяйте продукты и порции перед сохранением, смотрите историю и планируйте рацион. Сохраняйте дневник питания за выбранные даты в PDF из настроек приложения. Добавляйте продукты в общий каталог, сохраняйте рецепты и шаблоны. Приглашайте друзей по username: после принятия приглашения вы сможете видеть день и приёмы друг друга, сохранять доступные рецепты и шаблоны. Видимость своих материалов можно менять. Виджеты iPhone показывают итоги питания и мемы. По желанию подключите Apple «Здоровье» для шагов и активных калорий на главном экране и в виджетах: эти данные остаются на iPhone, не меняют цель питания и не видны друзьям. Тренировки можно добавлять вручную или импортировать из Apple «Здоровье» с отдельного разрешения. Вид, время, длительность и расход калорий тренировки сохраняются в вашем аккаунте ЧУЗИ для дневника и синхронизации; друзьям и AI-сервисам эти записи не передаются. По желанию ручные тренировки можно экспортировать в Apple «Здоровье» без рассчитанного в ЧУЗИ расхода калорий. Отдельно можно разрешить запись съеденных калорий в Apple «Здоровье» для использования в MESO и других совместимых приложениях. Аккаунты приложений не связываются. При подключении Apple «Здоровье» доступная история питания и замеров отображается в календаре ЧУЗИ на iPhone. Импорт веса, роста, талии, процента жира, безжировой массы и ИМТ требует отдельного подтверждения. По желанию разрешите экспорт актуальных показателей тела из ЧУЗИ в Apple «Здоровье», включая оценку доли жира по обхватам. Записи других приложений сохраняются. Замеры при регистрации сохраняются и без полного набора обхватов. Фото- и текстовый анализ доступен после согласия на передачу данных внешнему AI-сервису. Отказ не мешает вести дневник вручную. ЧУЗИ — инструмент для повседневного самонаблюдения взрослых пользователей. Оценки калорий и БЖУ, цели и подсказки носят справочный характер и не заменяют консультацию специалиста.
