Ratings and Reviews
Been using it for two years!
I read about Clue somewhere online during a time when my period was very irregular and decided to give it a go. The first thing that stood out to me was the logo but that aside, the predictions are pretty good for me. I mean they vary by like two days but that is good enough for me. I use this app to plan any outings or events, see when my skin will break out, when my mood is gonna go down and such. There is a cycle presentation of the data as well as a calendar format. Great for tracking it all and you can even create custom tags. This app also helped me figure out that the acne I get around my mouth is hormonal. It also helped me figure out that the reason I skip a month during summer around May is because of the stress I go through for my exams. It’s simple to use and the predictions are quite good. I’ve recommended it to my friends and they love it as well. After this, I find other tracking apps very complicated to use. It’s simple, accurate enough and discreet enough to fool anyone into thinking it’s a game app. Easily the best period tracking app out there, highly recommended.
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 👍🏻
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 😂
