This is by far the best language learning app I have tried - and I've tried many. my take is that it's not for absolute beginners of a language, but once you're able to have a basic conversation, this app is incredible. I need to learn very Mexico-specific Spanish, and this app gets insanely granular with extremely localized info about meanings, usage, even slang. It's incredible, and if I could buy a lifetime license I'd do so in a heartbeat.
