There are many apps out there to learn Mandarin. If you are a beginner like me, there is no beating this one though. Fun to use and you actually learn something, and since the last update it got even better! The only reason I don’t give 5 stars is because of the writing of characters questions. The screen reacts poorly to input with a pen, you have to be too precise to satisfy the hints which does get annoying. Also an option to try without hints would be very helpful, where you can just compare what you wrote to an example that pops up at request. As a request: could you incorporate more listening exercises without the answers in pinyin or pictures? Listening to mandarin speakers and understanding what they say is still my weak point, and at the moment I have to use other apps to practice that. One other request; could it be possible to allow users to play their music in the background, instead of the app taking over sound completely? I study a lot in places with a lot of background noise, it would be better for my concentration if I could block that out. As a last request, can you make it possible to do the reviews of lessons after closing the lesson as well? Would be great to quickly reinforce knowledge about subjects that way without having to do the entire lesson again. Thanks for the great app though! Absolutely love it!
