Requires subscription to another app to stop frequent ads
In order to stop the annoying ads in THIS app you must download and SUBSCRIBE to a separate app, called "Mag Hanzi", of which I know nothing. A bit on the deceptive side. I wouldn't mind paying several dollars for this app, but not a monthly subscription. Perhaps this app is just a small part of a larger learning system. Who knows? I guess that I can ignore the ads for the time being. But this app needs an explanation of its subscription model to eliminate ads.
