WARNING! If you do not know anything about Windguru and you are looking for classic weather app with animated weather pictograms, THIS IS NOT FOR YOU! :-)
BEFORE YOU INSTALL CONSIDER THIS:
This "Lite" app is not maintained anymore, and it is only a subset of the full web app available at https://www.windguru.cz
The Windguru website is made as a Progressive Web App (PWA), which means it can be installed and work just like an app on your Android device, it is continuously updated, takes almost no additional space on your device and offers full functionality.
IT IS HIGHLY RECOMMENDED TO USE THE WEB APP instead of this "Lite" one. More info at https://www.windguru.cz/apps.php
For those crazy users who still remember the very old app and prefer it (are you sure?), it still exists as "Windguru Old" on Google Play: https://play.google.com/store/apps/details?id=cz.windguru.wgappold
or install one of the old APK files manually from here: https://www.windguru.cz/down/android/
