About this app

App manual >

Solving a very personal pain, we have built a period tracking app that is SIMPLE. Simple to enter data and simple to glance at the info when it’s important to you.

Simple Cycle is targeted to specific women - women who live filled-out fast-paced life and know what matters to them. If you care only about tracking your past and future periods and fertile days (and sex life) without the additional options other apps are bloated with - you’ll probably love Simple Cycle!

Simple Cycle is super easy to use. You don’t have to create an account - our algorithm needs just two of your data and you’re all set for successful tracking of your period and fertile days, predicting your future cycles and keeping a record of your sexual activity. Simple Cycle also thinks about your cycle for you and reminds you in time of your next period and your fertile days.

Simple Cycle was designed and developed with love by awesome girls and guys from Machinery. Our guys now know everything about periods and love the app so much that they also decided to use it!!

To use Simple Cycle you don’t have to log in - all your data are stored on your phone.
Just enter the information about your last period date and your average cycle length and Simple Cycle will calculate and enter all your future cycles into your calendar. Of course, the more you use the app, the more accurate the predictions will become.

You can start using Simple Cycle even if you don't know when your last period was or you are expecting to get your first period – skip the intro screen requiring above mentioned data and start using the app by simply entering the information when your next period arrives. In that case, Simple Cycle will calculate your cycle length by setting cycle to 28 days by default, but as you keep using the app and recording your cycles, Simple Cycle will adjust the data.

- Fun color-coded calendar showing your period flow data and optional sex information discretely displayed
- Cycle day view of each day in a month with a chart of the current month including all your monthly data in one glance
- Statistics about your period and fertility for each menstrual cycle
- Statistics about your protected or unprotected sex history per cycle
Optional reminders of your next period and fertile days

Simple Cycle is used for tracking and recording your periods and fertile days. Every cycle of every woman is unique and can be influenced by various external elements, so your Simple Cycle may not always predict your cycle or your fertile days accurately. We recommend using Simple Cycle to track your periods and not to use it as a contraceptive method for preventing unwanted pregnancy.

I've switched phones but every time I do I make sure this app is on my new one. I've tried all the fancy tracking apps, Flo, Clue, Eve, etc. I have an IUD (and ADHD) and so being able to simply track things and not being prompted to take a pill or a quiz or 99 other things was important to me. After using this app for years, it knows when I'm going to start my period so accurately that it surprises even me sometimes. I'll see I'm supposed to start, think "nah" and what do you know, there it is!

Good, but the calendar is not super convenient UX wise, for me personally it's a bit uncomfortable to see what day is today, it's not really clearly shown, the date of your period is more visible than what day if the cycle and calendar it is today. Hard to exaplain what I mean :( anyway, overall good except some usability discomfort sometimes

I love this app for various reasons. The UI is nice a sophisticated. There's no ads, you dont have to create a login and it allows you to track when you have sex. One thing I would like is if they could add a pregnancy tracker in case you do become pregnant but otherwise this app is perfect and discreet.

What's new

Dear ladies, here is our very last update!

We have finally enabled exporting and importing of Simple Cycle data. So, fear no more - if you are getting a new device, you can just export Simple Cycle data, email the file to yourself and then import the file on your new device! Please be aware that you can not import data into another period tracking app - this export/import works just within Simple Cycle app.
We also fixed some bugs we discovered along the way.
