Ratings and Reviews
Sync up with your body to track your period and health cycles.
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 👍🏻
Clue is AMAZING!
I love using clue to track my cycle - it's an invaluable tool for checking my patterns during my period, and I've never had any issues with it. It has so many options for what you can track, and they're customisable too, so you can switch off anything you don't need or want to track. It's also so useful for going to the doctors, if you ever need to answer a questions you're all good if you keep yourself tracked on clue!

I’ve altered my review from 5 to 4 stars due to the issues my friend and I are having with clue connect. There is an inability to reconnect our cycles after disconnecting because they were not synced. I am really annoyed about this, and I hope clue do something to fix it. I have emailed them about it, but they’ve suggested creating a new account which isn’t something I want to do because I have at least a years worth of tracking on my current account. I hope clue sort this issue out, as it is really frustrating for both me and my friend. Otherwise, the app is still amazing for tracking my period and I will continue to use it, despite the flaws with clue connect.
