If you have occasional irregular cycles like almost 40% of women, then Ladytimer will be more accurate and reliable then the majority of apps that rely on simplistic average calculations.

Simply track your start period day every month. After that the app calculates the menstrual cycle for you. Enter your morning body temperature for precise fertility tracking. The app will use it to calculate ovulation. See when you are more likely to conceive a boy or a girl.

Enter and track symptoms, moods, notes, weight, intimacy, ovulation tests, birth control pills, etc for any day. Chat with other Ladytimer app users.

Your period tracker data can be saved online and imported to any smartphone when needed. Never lose your calendar data when switching phones. LadyCloud synchronization does it all automatically for you.

It's very easy to share your period calendar with your doctor or partner. Chose the data you wish to share.

I've used this app for many years now. At this point I shouldn't be so surprised that it can guess when shark week will bite... but I am every time. Absolutely worth the few dollars to get the pro version, I don't even remember how they differ but either way I'm happy to support the devs. Thank you so much! I appreciate the simple, straightforward UI the most.

I have been using this app for many years and have loved it. It's great for predicting cycles and also family planning. Suggestions - I have a variable (24 to 30 days) Once i pass the average number of days the app tells me that I'm late and to take a pregnancy test. Perhaps have an option to not mention a period being late until the max number of days to avoid unneeded stress? I would also love to be able to add more information regarding intimacy (like type of protection used, time of day)

Great experience so far. But I want to know how to edit my start/stop date. I mistakenly marked a wrong stop date for the period and needed to correct this. Kindly help on how to figure this out.
