Needs to speak to us
Messy I wouldn't call this a language learning app. It's more like a reference. You can choose (almost) any topic at any time, so it's confusing for people who actually want to learn. What I hate the most is the loading image in this app: apparently, 50languages advocates free language leaning, but I must pay for all the "lessons"? Don't get this app, you're better off finding a native speaker to teach you.
Purchase issue fixed.
Are you interested in learning Ukrainian, but just don't have the time?
