I am glad there is an app to install on my LMDE5 machine. I usually use the website which is complety fine. I use the app on my Android and is great. 4 star for overall usuage and never having a problem in the few years I've used it. 5 stars I gave because it is free. Thank you!
Indeed very simple but very good. Can synchronize on all devices. Very easy to use. I like it.
