This version contains a rather dirty workaround to fix login on devices running Android 5.
In the settings the password field is now a text field (no asterisks, your password is visible as text), this allows the app to send the login to server correctly. If you are OK with this, you can login, if not then please use the app anonymously.
Don't be afraid! Windguru is not dead, we are working on updates to the website and then we take a look at the apps again too, stay tuned!
