Blum is a free Android app developed by Climb Inc. that aims to provide users with simple conclusions about their current pregnancy status. While it is important to note that the app does not replace laboratory tests, it can serve as an initial guide for those who have doubts about a possible pregnancy.

With Blum, users can input relevant information about their menstrual cycle, including the start date and duration. The app then uses this information to calculate the likelihood of pregnancy based on established patterns. It provides users with an easy-to-understand interface that displays the probability of pregnancy, allowing them to make informed decisions.

Blum's user-friendly design and straightforward approach make it accessible to a wide range of users. Whether you are trying to conceive or simply want to track your menstrual cycle, Blum can be a helpful tool in understanding your current status. Keep in mind that the app should be used as a guide and not as a substitute for professional medical advice.
