App Store and Google Play reviews


Amazing! I’ve been searching for an accurate app where I can log my symptoms and check the pollen count, specifically grass pollen. I came across this a year ago but the app only worked in Germany. I am thrilled it now works in the U.K!! I don’t know where I would be without it. And I can’t believe it’s free!


BRILLIANT! Love this app very useful. A must for any sufferer.


Klara is excellent, it keeps me aware of the pollen before I go out.


Well specified app with superb insight as to what factors may adversely impact you.


BRILLIANT! So interactive and well made, I'm dumbfounded as to why it doesn’t have 10 million + downloads! It’s such a well thought out and useful app! One problem is that the only link that actually works to create an account is on the 'My page' page, the other links don't work once you receive the email


Amazing app. Truly helps me predict when my allergies will be bad, and what activities I can do that day. Also helps me track how I feel and what medicines I’ve taken.
