Лучшее из лучших

Я не понимаю почему весь мир не пользуется этим реально , я пытаюсь по тихоньку всех перевести сюда )

Response from developer

Спасибо огромное 🥹

Восторг!

Данила, вы красавчик, очень надеюсь что в вашем приложении не будут каждую секунду всплывать на весь экран предложения купить подписку как в том, что я удалила, выбрав ваше. И ещё одно пожелание, уберите карту смерть из карты дня, поверьте в первый день цикла это может просто добить🤣🤣
Оформление очень красивое!!!

Response from developer

аахах) спасибо большое за отзыв и 5 звезд! Кстати карта "смерть" оказалась не такой уж и страшной как выяснилось, поэтому относитесь к этому проще 😅 Надеемся оправдать ваши ожидания, всплывающих окон и прочего не планируем - ценим наших пользователей 🫶

С обновлением дизайн стал хуже(

Скачала и пользовалась во многом из-за очень симпатичного приятного внешнего вида, а с этим «жидким стеклом» стало как-то менее приятно

Response from developer

Понял, спасибо что дали обратную связь! Постараемся в будущих обновлениях что-то придумать, чтобы исправить косяки в дизайне и общем впечатлении. Мы точно не хотели сделать хуже 🙏

Another man's toilet version of an app exploiting women's vulnerability with an Al gimmick

Look, Flo has its flaws, but at least they actually consulted female experts to move cycle tracking forward. This app is the complete opposite. The developer expects praise because he allegedly built this "with love for his girlfriend" as if the bar for what men do for their partners is so low that using her as a model organism for an AI experiment is romantic. Honestly, buying her a huge diamond ring would have been a far better use of investment than launching this audacity of a product.

Did the creator honestly think prompting generative AI on his laptop was enough to support women through unimaginably stressful days of debilitating cramps and crippling depression?

The app claims to be grounded in women's health research, but anyone who actually reads the science can see right through it. Marketing an unverified "AI sister" chatbot to a girlie stuck in a high-progesterone mental slump doesn't help, it actually preys directly on our vulnerability! Throwing a hallucination-prone bot at someone in severe distress can easily backfire and compromise mental health.
This isn't innovation whatsoever, it's laziness dressed up as empathy to make a quick buck off our cycle. Girls, do not trust this app with your wellbeing.

Пофиксите баги, приложение пушечка

Ошиблась с выставлением даты приема кок, не могу теперь поменять. Приложение классное, даже от бесплатной версии получаю удовольствие, возможно чуть чуть поюзаю и куплю. Спасибо

Response from developer

Здравствуйте! Баг уже пофиксили, обновите пожалуйста приложение 🙏 Спасибо, что несмотря на это поставили 5 звезд! 🥹
