Update (2022-03-23: Downgrading again to 2* because the removal of the Sentence Discussions has to be one of the worst decisions ever made by the company. It was super helpful trying to understand the quirks of a new language. I will be moving on from this app shortly, sadly. **************************************************************************** Update (2020-10-28): I'm downgrading from 5* to 3* after the recent Hearts update. Besides the typos I used to make I used to be able to freely try different version of the typing exercises to see if they were accepted, which enhanced by learning experience but no more. They just want you to transfer over to the paid version. **************************************************** Original review: Soon I'll be an expert I hope! The lessons are neatly organized and make it fun.
