Great app, helpful devs :)
I’ve been trying a variety of apps since finishing Duolingo/Hello Chinese as these don’t quite cover HSK4 in its entirety and this app has been extremely useful for filling in the gaps. My weaknesses are listening and speaking and the recordings in this app are very good and have helped me with my pronunciation a lot. The app gives you a nice array of methods to practice the language. I feel like it does a good job of exposing the vocabulary to you over and over through the various exercises which works very well for retaining what you have learned. I did run into a small bug but after contacting the devs it was resolved in the next update. Really friendly and helpful, even sent me an email to let me know that the fix was in. I also like that this app is a one off payment rather than a subscription like pretty much all the other apps. It’s a great companion to pair up with other learning methods such as watching/reading native content.
