Just loaded this app and notice on startup it asks for Google credentials. I understand that my viewing histroy and preferences will only be save with using an account.
But always hesitant to give my credentials to 3rd part apps.
Does anyone know how safe this app is?
It's safe, no need to hide your login. It scrapes the web interface and presents it in app form, it's also open source and why you don't have to worry about your login as the code has been audited by many people.
