Ladies, we all know that periods can be an enormous hassle if you're not keeping track—but then, keeping track is a hassle in itself. Period Tracker aims to make planning for your period much simpler, with a free menstrual calendar app that not only lets you track your period, but will also predict your next one.
The app includes a bevy of features, but simplicity is the rule. Inputting your "data" requires as much complexity as you want. When your period starts, you tap a single button; then, if you feel like it, you can add more information each day. The app can track everything from your symptoms (headaches? nausea? bloated?) to your mood. A freeform Notes box lets you record extra information as well. It also calculates how long it expects your period to be, and will predict when your next one will start.
And if you're tracking your period out of more than curiosity, and are instead trying to get pregnant, Period Tracker also calculates when you're likely to be ovulating or "fertile." You can also note on which days you and your partner have been intimate, if that's your goal.
Oh, and Period Tracker can be discreet, too—no obvious icon, and the option to password protect the app. Ve-ry nice. If you want to export the data, however (say for your next visit to the doctor) the app will allow you to send out your data via email.
So, if you're a woman in search for a way to track your menstrual schedule, check out Period Tracker. It comes in both paid and free flavors, but the free version has all of the functionality described.
