Lady Log is a simple period tracker app that allows you to easily record your menstrual cycle without any advertisements. It provides essential information like the day of your cycle, countdown to the next cycle, customizable themes, integrated calendar for past and future periods, statistics on cycle length and duration of periods, and can even estimate fertile days. The app prioritizes data security by working without registration and storing information only on your phone. While it’s a helpful tool for tracking your cycle, it’s important to note that the fertility predictions are estimations based on entered data and should not be used for contraception.
