At the moment, klarify is available in Ireland, the UK, Germany, Denmark, the USA and Slovakia. To download the app, you need to be logged into one of the respective countries’ App Store or Google Play. You can access the app outside these countries, but you can only see the pollen count and forecast, for the countries, where the app is available. Also, the allergy log only works in these countries. This is because it matches your log with the actual pollen count of your exact location. Weather and air quality forecasts are available in most parts of the world.
