The concept looks extremely interesting, but (like the vast majority of language learning tools) Albanian is not supported. I might give it a try for German though
I'm planning to add some more languages after improving the UI. Right now the dropdowns to select languages feel unwieldy with so many options. If you want me to let you know when I get around to adding Albanian, email me at $MY_FIRST_NAME@readlang.com or send a message via https://readlang.uservoice.com/.
