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.

30:21 is a habit tracker that does more than tick boxes: it runs you through a cycle — 21 days of action, then a week of reflection. HABITS • Create habits with your own icon, colour and schedule — by weekday or every N days. • Check them off with one tap, watch your streak and keep the chain unbroken. • Reminders at the time you choose. THE 30:21 SPRINT • 30 hours of energy over 21 days, split across three spheres: Drive (I do it even when I don't feel like it), Foundation (the daily basics) and Joy (I owe myself rest). • The energy ring shows where your hours go; the cycle map shows where you are. • Reflection week: what you did, what you didn't, why, and what you'll change. Save the summary as a PDF. • Carrot and stick: the reward for finishing the cycle and the price of quitting — both set by you. WATER • Glasses, a daily goal, reminders with quiet hours at night. STATISTICS • Streaks, perfect days, a six-month activity calendar, week-by-week trend. MEDITATION • Six nature sounds and a breathing circle: inhale — hold — exhale. CHALLENGES • Join shared challenges or create your own — it becomes a habit for the chosen number of days. • Free for everyone until December 1, 2026, to celebrate the iPhone launch. PREMIUM (subscription) • Unlimited habits (free plan: up to three). • Food scanner: photograph a meal or describe it in text to get calories, protein, fat and carbs. • Backdated check-ins, full statistics, the Katana theme. The subscription renews automatically unless cancelled in your Apple ID settings at least 24 hours before the end of the period. Payment is charged to your Apple ID account at confirmation of purchase.
