I’ve used Skritter off and on for a couple of years, and one thing I’ve always wondered is whether it is possible to add an optional entry box when studying pinyin on Skritter. For instance, 香蕉 would be the prompt for entering xiang1 jiao1.
It used to be like this on the desktop site, but I’m guessing it isn’t available in the iOS or Android mobile apps?
I prefer the unbiased judgment of the program to my own estimation as to how well I remember the tone and syllable.
