A great and non tedious learning experience
I think this is a great method for learning new grammar and vocabulary, which any learner of mandarin should get. The vocabulary builds on itself and works much like duo lingo, though I think the translation in Chinese skill is much better. Just make sure your phone is set to a language you know well, because thats the language that the app will be teaching you in. My phone is always set to Japanese, so I dont use this app as often as it deserves. But overall, its a great and entertaining learning device.
