I don’t wish to upset the creators of Mimo by giving a low grade, because Mimo is great. It works like any of the better teaching apps out there (Duolingo, etc). Very easy, seemingly full of content. ....However, if you make mistakes three times, you have to wait four hours before you can resume, and if you make another mistake, you’ll have to wait another four hours. Patience is key. OR, you can spend $60 and by the pro. That might not be a big deal to you, but if Mimo is to encourage betterment in a secondary skill (for many of us folks already working hellacious hours) as to better our lives, I don’t find such a high price-tag warranted. Maybe a $10 flat fee, MAYBE...even though the creators should definitely get paid for a nice app, taking money from poor to lower middle-class folks for something that, even if aced, wouldn’t land anybody an actual job could be considered pretty low, ethically....just saying.
