Beautiful UI but app is a bit buggy. Tried to login via facebook on an LG G3 D855 running Android 6.0 and it fails. So, I created an account in order to proceed. Setting up after first login and the app is unable to find my location with GPS active while other apps can. I couldn't find also a way to update my list of locations after the initial setup, there seems to be no such option from within the Settings icon. Looks promising when eventually it gets functional. ;-) The problem persists after upgrade.
I liked the personalised daily recommendations for user groups. Very useful.
Nice and useful
Location does not work. Why the hell do I want to know the air quality in Greece when I am in England
