Your Cycles

Lily will tell you exactly which rules it applies to evaluate your cycles, and why, as well as the results of these evaluations, and what they mean for your fertile and infertile phases.

Lily will also give you a list of tips and tricks you can apply to help Lily become even more accurate when tracking future cycles.

The Calendar

Navigating back and forth in time in months or even years is as easy as pie with Lily's calendar. While you can quickly go back and forth a few days from the main menu, the calendar allows for greater jumps in time while displaying the most important information like infertile days, the Peak Day, along with the cervical fluid, and the estimated period and the strength of your flow.

And, just like with the graph, you can tap any day to see a detailed overview of the data you entered for that day.

The Graph

The graph in Lily is where all the information you chart comes together to be visualized. Easily keep track of where you are in your cycle, see your temperature curve and access all additionally charted information for each day right in the graph with just one tap!

You can choose to display the graph horizontally or vertically.

Chart Your Temperature

Chart your body basal temperature in either Celsius or Fahrenheit.

When using one of its symptoms-based evaluation methods, Lily will use your entries to detect your temperature shift according to the rules to evaluate your fertility.

Track Your Period and Symptoms

Track and chart information on intermenstrual bleeding and your period such as the strength of your period and accompanying symptoms, like nausea or cramps.

You can easily start a new cycle with just one tap or use the graph's edit mode to tell Lily to start a new cycle for you.

Evaluate Your Cervical Fluid Quality

Your cervical fluid is an important indicator for your fertility. Chart your cervical fluid and its changes throughout the cycle.

When using one of its symptoms-based evaluation methods, Lily will use your entries to detect your cycle's Peak Day, the day with your most fertile cervical fluid quality.

Looking at a white screen first thing after waking up is not fun.

To be easy on your eyes, Lily can switch between a light and a dark theme, either manually or automatically, using your device's display brightness, or based on the time of day.
