### 5/5 — Thank you

*2026-06-30*

Increíble app, justo lo que buscaba en un solo lugar saludos desde qro a increible persona que la creo

### 1/5 — Не работает

*2026-05-21*

Было мои любимым приложением, пользовалась более 6 лет, перешла с андроида на айфон и не могу войти в приложение со старой почтой, так же не могу зарегистрироваться как новый пользователь, бесконечная загрузка.
Очень расстроена, это было моим любимым приложением, теперь придется искать другое(

### 5/5 — Крутое

*2026-05-19*

советую)))

### 2/5 — Не работает на айфонах 17+ совершенно

*2026-04-04*

Перешла с андроида на последний айфон, скачала это приложение т.к. на андроиде оно у меня было любимым, скачала, а оно не грузится абсолютно на моменте регистрации после ввода пароля( почините или удаляйте его для ап стор тогда, раз не хотите что бы оно работало для пользователей iOS((

### 3/5 — При входе долгая реклама

*2026-03-31*

Уберите рекламу при входе в приложение. Минуту надо ждать - игры  детские рекламируют…

### 3/5 — Лагает ((

*2025-10-29*

На андроиде идеально работало, пользовалась несколько лет. На айфоне вылетает постоянно, то комментарий не ввести, то кнопка сохранить не активна, а под занавес никак не отметить дни цикла- выдает ошибку и зависает

### 5/5 — Отлично

*2025-10-04*

Ничего лишнего! Только календарик и симптомы, рекламы нет, кайф! У меня никогда такой удобной штучки не было, установила по совету подруги🥹

### 5/5 — Лучшее приложение для месячных

*2025-10-03*

Как же долго я искала такое минималистическое приложение - никакого визуального мусора и оформления, из-за которого порой не понимаешь, куда нажимать, никаких никому не нужных статей и новостей, трекеров веса и рецептиков, никаких «отметьте количество капель, что болит, где чешется и как настроение». Огромный плюс, что можно отключить показ овуляции и возможности забеременеть для тех, кому это еще или уже не надо. Это идеальное приложение - ничего лишнего. Надеюсь, что так и останется. Спасибо!

### 5/5 — заголовка не будет

*2025-06-14*

Лучшее приложение эвер ❤️‍🩹

### 5/5 — Хорошее и понятное приложение

*2025-05-20*

Простое и понятное приложение для отслеживания цикла. Не знаю как ведет беременность, еще в этом моменте не вела его
