최고의 어플

여러가지 생리 어플 사용해봤는데 이게 최고에요 엄청 깔끔하고 필요한 기능만 있고 주기도 진짜 잘맞아요 어플 유료결제 해본거 처음인데 너무너무 잘쓰고 있어요 감사합니다🤍

너무 조아요!!

제가 생리 주기가 제각각이고 안 하고 건너뛰는 달도 있어서 예정일은 필요없고, 그냥 기록용으로 쓰고있는데 앱이 심플하면서 예쁘고 이 아이콘? 그것도 심플하구 예뻐서 너무 잘 쓰고있어요 ㅠㅠㅠ 앱 사용한지 2년 좀 넘었는데 이렇게 꾸준히 기록하니깐 넘 편하구 메모 기능도 있어서 더 좋아요!! 그리고 생리를 언제 며칠씩 했는지 한번에 보여주는 기능도 있어서 넘 편해여👍

Simplicity and functionality!

Finally, a cycle tracker that provides just what it’s ment to. No annoying ads or overwhelm features, just simple tool for tracking your cycles. Perfect! Do not change a thing!

Great App

After being recommended several different period tracking apps, this one is far superior for my needs.
It is exactly what was looking for; simple and easy to use.
I am past the point in my life that I need to track ovulation, and wanted something that would remind me my period is coming, have a calendar to show, and calculate when based on my average challenge is.
As a woman that is in the beginning stages of perimenopause, my period is no longer as predictable as it once was. The three day until period starts is a such a wonderful feature with them beginning to become a little closer together.
I highly recommend if you are in the same point in your life as I am, and want something straightforward to use.

Deleted?

I logged in and my data was gone and it told me I didn’t have an account. Now I have no historical information and need to start all over with a different app. Very frustrating
