Solving a very personal pain, we have built a period tracking app that is SIMPLE. Simple to enter your period 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.

Very simple & very accurate

I have a hard time finding something accurate especially period predictions, so this tops my expectations. I do wish thought it had on it, things like did you take plan b, or sick because those kind of things do throw off a woman’s cycle. Overall this app is amazing and I love it. I got off all the other apps because they weren’t accurate and hated the notifications of questions ladies posted that made you want to delete the app like Ovia does. It’s peace and quiet. Simple and accurate. My new app. ♥️

Little suggestion

Thank you for such an amazing app!

The only little suggestion that I have is maybe you could add a function to let users quickly add a note about the symptoms or anything that they want to note about the day? I feel like that could be really helpful, and doesn’t really harm the simplicity of the app. People could choose to use it or not. Anyway, I like your app a lot! Thanks again!

Developer Response ,

Thank you for your kind words and your suggestion, we'll take it into consideration!

Great App but please add

Truly a straightforward and simple app to use! Like the other reviewers have mentioned before, I would find mood and symptom options for each day to be helpful. I like tracking my cramps - ex. 1 - no discomfort, 2 - little, 3 - medium, 4 - intense to give an example. At the very least, a notes section for each day would be helpful.

Developer Response ,

Hi! Thank you very much for your review! We won't be adding specific symptoms in order to keep the app simple, but we do plan to add a kind of note taking, so hopefully that will be helpful to you. Have a great day!
