Abstract: A wearable device allows women to track their menstrual cycle by rotating or sliding a marker that will tell her every day where she is in her menstrual cycle. This device can be shaped in multiple ways. In general, the device has two or more interlocking pieces that allow the user to manually move, e.g., rotate or slide, a marker shaped on one of the pieces with respect to the other piece to highlight indicia, such as a number or icon or color, that represents a day in the menstrual cycle. The indicia can be hidden within the design to protect the user's privacy. In one implementation, the device is attached to a chain, rope or other form allowing it to be worn around the neck, typically under the clothes, like a pendant. Another implementation is shaped like a bracelet, allowing it to be work around the wrist. Other configurations to be worn on other parts of the body also are possible.
