Never be ambushed by Aunt Flo again.
So you're on a date, and it's going pretty well. You head to the restroom because all that wine is weighing on your bladder, but your mood sours: You realize your period has made an unexpected appearance, and you don't have a tampon.
Using a period tracker app can help you avoid that kind of surprise scenario. But that's not the only reason you might want one. A period tracker app can also help you know what a "normal" period is like for you, so you'll be on top of it if something isn't right. Having that data on hand can then make it easier for your gynecologist to figure out what's wrong.
Keeping track of your period via an app can also help pinpoint your fertility window if you're trying to get pregnant—or trying not to.

Lots of different apps on the market right now can track your period. To find the best, we rounded up 5 that come highly recommended by reviewers and by Dr. Greves herself.
