User reviews

Лучшее приложение

Очень понравилось данное приложение, пользуюсь с большим удовольствием. Красивый визуал, очень логичный и понятный интерфейс, в целом календарь получился очень заботливый и милый, все удобно и понятно. Особенно порадовало, что можно выгрузить пдф-файл для врача. И очень понравилась информационная лента с рекомендациями для каждой фазы цикла.

Response from developer

Спасибо большое за отзыв! Очень рад, что все понравилось.

Better communication tool

Instead of awkward talks, I just update my status. My partner checks it and understands what kind of day I’m having. The little support interaction feels simple but keeps communication open.

Fun with my close friends

I connected with two close friends and we compare cycle phases. It’s surprisingly fun to see when we’re all in the same mood zone. We tap support and send memes when someone logs cramps or stress.

Easy to share updates

The interface makes it simple to share mood changes with my boyfriend. When I mark that I’m overwhelmed, he reacts with the support feature and offers help. It turns mood swings into teamwork instead of conflict.
