It's for guys and girls

Bombaclock’s notifications are individually tuned to the two genders - make sure you enable messages and notifications to enjoy the sassy fun of Bombaclock!

Bomba starting date

You can set the date of the current/previous cycle, as well as the cycle length. Over time you can re-enter the exact starting date and Bombaclock will calculate a better cycle average for you.

The variability of menstrual cycle lengths is highest for women under 25 years of age and is lowest, that is, most regular, for ages 35 to 39. A good starting point is 29 days if you aren’t exactly sure of your/your partners cycle length.

Bomba countdown

With the increase of pink we are nearing the period - the app will begin to notify you of the impeding period a few days beforehand. The app will also provide tips and ideas for sweetening the deal and being prepared.

The Bomba is here!

The three drops indicate that the period has begun. After a few days it will go back to the default bombaclock screen. Time flies!
