Downloaded this about a month ago, and have been using it to learn how to speak, read, and write in Mandarin.
The exercises are similar in presentation to Duo Lingo, but also cover how to write Pinyin characters. This is a nice touch. As you can imagine, thats an important feature to have, as Asian character markings are structured differently from Anglo-like ones.
A must have if youre looking for a free companion to begin your language-learning journey.
