[Introduction to Basic App Functions]
1) Basal Body Temperature Recording & Basal Body Temperature Graph
Recording your basal body temperature automatically creates a graph, making it easy and sustainable!
You can also record menstruation, whether or not you had sex, and comments, and these are reflected in the basal body temperature graph.
The recording screen allows you to move dates, making it convenient to record several days' worth of data at once.
It also supports data transfer from the MC-652LC women's electronic thermometer (Omron), making daily recording easy!

The graph displays your menstrual cycle, allowing you to quickly see which day you are.
Furthermore, there's a function to save 60 days of graph data as an image for printing! Convenient for doctor's appointments♪

2) Recording and Predicting Menstrual and Ovulation Dates
By recording your monthly menstrual cycle dates, you can accurately predict your next period and ovulation dates.
It also displays your current fertility level (how easily/difficultly you can conceive) on the home screen to support your fertility efforts!
You can also view a list of your menstrual cycle dates, making it easy to check each cycle♪

3) Notifications and Alarms
The app will notify you 7 days before your period and 3 days before ovulation.
You can also set an alarm (wake-up function) for your daily basal body temperature measurement.

4) Fertility and Body Content
You can view messages from obstetricians regarding fertility, and columns from the Lunarluna Family Course on pregnancy, childbirth, and childcare.

5) Basic Knowledge of Basal Body Temperature
"How should I measure it?"
"What kind of graph is good/bad?"
"Can I tell if I'm pregnant from my basal body temperature?"
And much more! All the essential information is included.
This app is perfect for those just starting to try to conceive or those new to basal body temperature.

[Data Integration with Google Health Connect]
