Perfect App for me

this app is what I have been really looking for…Thank you!!

임신관련

생리주기관련 안내는 좋은데 임신관련주차정보에 틀린내용이 너무많아요

임신중 이라는 체크가 있으면 좋겠어요!!

임신중에는 생리가
안오는데 자꾸 생리안한다고 알림이 떠요 임신중이라는
체크가 있으면 좋겠어요

8년째 쓰고있고 너무너무 좋습니다.

다만 한번 결제로 영원히 광고 제거하고싶은데 프리미엄은 계속 사야해서 주저됩니다...다른 구독 방식도 검토해주셨으면 좋겠습니다.

FAQ

What does Bom Calendar do?

Bom Calendar is a period tracker that helps you monitor your menstrual cycle, predict your next period, and estimate pregnancy probability. It also allows you to log daily body conditions, mood, symptoms, and weight, providing insights into your overall health. The app offers customizable features and secure data management.

How accurate are the period and pregnancy predictions?

Bom Calendar uses the same standard contraceptive guidelines and period calculation methods employed by the American Board of OBGYN. This approach aims to provide more accurate pregnancy probability and cycle predictions compared to many other period tracker apps.

Is Bom Calendar free to use?

The app offers a free version with core tracking features. However, certain premium features, such as sharing mood and health status with friends, exporting menstrual cycles and basal body temperature as a PDF, and enjoying an ad-free experience, are available through in-app purchases.

What devices is Bom Calendar compatible with?

The description mentions sign-up options via email, Google, or Apple accounts, and secure data backup/restore functions. This suggests compatibility with iOS and Android devices, as these are the primary platforms for such account integrations and app installations.

Can I share my data with my doctor?

Yes, you can export your recorded data, including periods, medication, mood, and symptoms, into a professional PDF report. This report can be neatly organized and easily shared with your doctor for medical records or consultations.
