Clue is much more than just a period tracker – it’s an easy-to-use solution that helps you make sense of your periods, fertility, pregnancy, and menstrual health. It’s a scientific and fluff-free way to learn about your body and discover unique patterns in your menstrual cycle.
Thanks to Clue, your period and menstrual health tracking are all in one place. The Clue app predicts your period, PMS, and fertility, and helps you find unique patterns in your menstrual cycle. Great skin when you ovulate? Headaches during PMS? Learn about your unique patterns with 30+ tracking categories from birth control to cramps, emotions, skin, hair, sleep, sex, pain, moods, cervical fluid, and more. Plus, set reminders so you never get surprised by a period again. Clue adapts to you and your unique cycle: the more you track, the more you learn, and the more you start to live in sync with your biology.

So reliable (worth a read)
So after using the clue app over a period of 21 months I find that the clue app is one of my go to apps. I’m the type of girl that stresses over scheduling events around my period. I find it a very uncomfortable week and tend to hide away. At first the clue app isn’t 100% accurate but that is because it isn’t psychic. It’s important to constantly put as much information into it as you can to allow it to become accurate and gain a better understanding of your cycle. After a few months of using the app, I could rely so much on the dates it told me I was going to come on, I was super prepared and it’s always right or 1 day different. I find that my periods are quite heavy and I tend to get a lot of pain. I used the app to show the doctor days from past months to pinpoint as all my information is there, even from the littlest detail of if I was craving chocolate on 17th June 2017 😂. I recommend this to everyone. Try it and my advice, stick to it. The longer and more frequently you use it the better it gets. It knows me more than I know me! I love my period calendar 😂
Absolutely great (but, like anything, you can’t rely on it 100%)
**worth the read** So I’ve used this app for a year or so now and it’s a great thing to have to help you track both your cycle and other features such as exercise, weight gain/loss and other habits and how you’re feeling each day. I use it regularly and it is very useful, I haven’t downloaded an other app for this purpose so I can’t compare it to others but i can easily track both mine and my friends’ data on this app which is good.
Hoooooowever...just bear in mind that the app, arguably like every other app for this purpose, will not be 100% reliable, and so even though this advanced technology seems like it is extremely accurate, you should always be prepared just in case your cycle is a little earlier than expected (a mistake easily made if the app told you your cycle would only start when you got back home from holiday, when in fact you were caught by surprise in the last few days of your holiday, for instance). Everybody’s body is different and so many reviews will say that Clue has never been inaccurate for them regarding their cycle, however this may not be the case for most people.
Hope this helped, and overall a very useful app to have at all times 👍🏻
Have had Clue almost 4 years and would recommend completely
Have been using clue for almost four years, when I first started tracking I had downloaded a couple other apps which have since been deleted, clue I reckon by far the best out there. Can't fault it at all, beautiful and clear design, fantastic features, a must have for tracking cycles and symptoms that come with it. Also if you do have any queries concerning the app they are fantastic at getting back to you.
For reviews that say it’s not always accurate... clue does always state how are bodies are not clocks so sometimes on odd occasion it could predict a day out but it’s down to our bodies not clue. The more you track the more precise the predictions are. It takes your averages and predicts from this but our bodies don’t always go by averages and many things we do in our daily lives could affect our cycle which is why clue let’s you track lots of other features and sometimes it can make sense maybe why a cycle came on earlier or later. Hope this helps!
