Danish and Irish on iOS!
They are here.
Hmm... Decisions decisions.... Take lessons with the app for ease of use and speed, or stay on safari to be able to report mistakes and leave comments...
I usually use iOS for (easy ;-)) practice and the web for new stuff. Further big plus for safari/web vs apps: you can report errors or bugs and make comments. Negative with safari: having to click everything twice to confirm :-/
Fantastic. Good to hear. Those are two I'm considering for the future.
