Cycles - Period tracker with fertility calendar and reminders for both of you.

By Perigee

Open iTunes to buy and download apps.


A period app your won't mind sharing with Him! Cycles keeps track of your period and fertility without all the inputting and upkeep of similar apps. Irregular cycle? Just rotate the dial to the first red day when your period arrives. That’s it! Cycles automatically adjusts your cycle lengths and forecasts as needed.

Cycles is the only app of its kind designed for *both* of you. We've made it fun to invite your Partner to connect and keep up with your cycle. That way he will be more prepared to provide emotional support, plan trips and romantic evenings at the perfect time without having to ask, and know your most fertile days when planning a pregnancy. Husbands and boyfriends love this app as much as you do!

Track your current period in one glance with a beautifully designed Cycle view, and see upcoming cycles in a scrolling monthly Calendar. Set personal reminders to make sure you remember to Take the Pill, or receive discreet notifications like "The bees are coming" to pencil in romantic evenings when planning a pregnancy. And an optional passcode lock keeps your privacy absolutely secure.

Cycles uses modern and scientifically-researched fertility tracking to help predict fertility, with accuracy up to 95%!

When calculating fertility for pregnancy with natural family planning, Cycles takes advantage of scientific research thats is more accurate than the 'rhythm method' of yesteryear and has a real-world failure rate comparable to that of condoms. Even so, this app is designed for informational purposes only and should not be used to prevent pregnancy.

Customer Reviews

Okay app. But needs some improvements.

I just downloaded the app and I have read some of the previous reviews before leaving mines and the app seems to have plenty of opportunities to take care of. Because indeed, there is no pregnancy option. Wonder if they are taking care of that because this isn't a "free" app. I decided to give it a chance to pro in order to receive notifications I do not like the fact that my partner has to pay for something I had already paid. And the app itself, I downloaded it for the same reason others did, which was to keep my partner in track about what's happening. In my personal opinion there should also be a pill icon in the calendar when a pill is been taken, find this miss-leading because instead there's a pen which is also used when leaving notes. Gave it a 5 star rating instead of 3 to empower them because I'm positive about the customer service of this app. Please don't make me regret it. Thank you.

A REAL HELP for husbands

Been married for 16 years, and with four kids, our live have to be pretty scheduled or it's just chaos. This definitely helps with a major area of our lives. All husbands need to use this app. Just getting up in the morning and having a notification that "stormy days ahead" really helps - you know when to step lightly and also makes you more compassionate, patient, and understanding with your wife, knowing she's at that point in the cycle and is going through cramping, bloating, and pain. At those times I'll frequently offer to take the kids or fix dinner or just send her to Starbucks knowing that she feels like garbage for a few days. The Bible says to "live with your wife in an understanding way," and this app helps me to understand how to know her, understand her, and meet practical needs.

This app has been a real help! I really recommend it. Especially to Christian husbands.

No pregnancy option and app fee for both phones

I got really excited about this app because of the option to share my cycle with my husband, however I have been very disappointed. The app charge is a separate fee for both phones- his/hers. $6-7 total seems steep for an app this basic. There is no pregnancy option, so if you get pregnant you have to write it in the notes...!? It also changes your previous cycle info if you change your current period date, which seems inaccurate. Would also like to see more options for the emotion and body sections. For the price of this I would really like to see some updates.
