Track your cycle. Clue makes it super easy to keep track of when your cycle occurs. Once you input the data, you can see your cycle as a circle, with 21 or 28-days. The circle is marked when your period happens and even when you're going to be the most fertile. And to top it off, you can track your mood during your period and see if it has anything to do with your cycle over time.

Track your cycle
Clue gives you clues

Clue gives you clues. Clue not only keeps track of your period, but it helps you remember too. With Clue, you can set reminders for when your cycle and fertile windows begin, when you're going to have PMS, and more. All of your data can be synced with HealthKit, so you can have full reports to provide doctors if needed. And over time, Clue will give you insights into your unique patterns, so you can learn even more about your body than you previously thought.

What is it about?

With Clue, women will be able to understand their own cycles much better. Not only does Clue serve as a period tracker, but it can even alert you when you're going to have PMS, so be warned, everyone! It also can track your most fertile ovulation times, in case you and your partner are attempting to get pregnant in the near future. Clue is also capable of tracking your unique patterns, such as pain, sex, bodily fluids, moods, and more. And if you have an Apple Watch, you're able to view your cycle info as a glance, so it's discreet and always ready when you need it. It's also fast to input your data into Clue and get fairly accurate predictions, so make sure to give this one a try if you're looking for a complete period and fertility tracker.

For those who...

  • Want an all-in-one women's health tracker
  • Want an Apple Watch companion app for tracking their menstrual cycle
  • Need a warning before their PMS is likely to hit

Not for those who...

  • Are fine managing period tracking on a regular calendar
  • Want informative articles to go along with their period tracker
  • Need an app that can share information directly with their partner

Why we love it

Clue has a sleek interface that is colorful and fun, not pink and girly like you'd expect a period tracker to be. Plus the information that it can track is comprehensive, it's fast, and there is an Apple Watch companion app to go along with everything.
