5 Apps That Make Tracking Your Period (and Any Pesky Symptoms) So Much Easier

Cost: Free for Lite; $10 for Deluxe

If you just need the basics, Period Tracker is a great place to start. I've personally used this app since my sophomore year of high school. It allows you to log any symptoms you're experiencing (think: spotting, headaches, bloating), as well as if you've had sex (and if protection was used). If you want to chat with other users, try upgrading to Deluxe.
