To generate your ovulation calendar you should provide the following details:

- Date of the last period (on the calendar on the main tab).
- Average length of the periods (on Settings tab).
- Length of the Luteal Phase (on Settings tab or use default value).

The application works best for women with regular menstrual cycles, the average cycle length is also a valid way to predict when the ovulation should happen.

### 1/5 — Don’t waste your money

*2023-03-31*

Can’t believe I paid to upgrade to the “full version”. Waste of money and personally the app is of zero benefit if trying to conceive. Can only add in menstruation and intimacy information. Can’t even log any ovulation results!

### 2/5 — RIP off

*2020-09-04*

I bought the full version of this app versus the free one and it’s no different. Just down load the free version you pay £3.99 and the app doesn’t give anymore info 😤

### 3/5 — Average

*2019-10-16*

This app is interesting to help with planning for the gender, but finding it not as user friendly for tracking periods as other apps as it doesn’t let you adjust your cycle on a monthly basis. So will take a while to be accurate.

### 2/5 — Что делать тем, у кого цикл не регулярный?

*2019-04-08*

Использование приложения ужасно неудобное! 
Цикл автоматически проставляется за тебя на весь год, если что-то сдвинулось — единственное, что можно поменять, первый день менструации. 
А если вместо автоматических 4 дней, было 3...ваши проблемы, отменить день никак нельзя 🤷🏼‍♀️
