One thing that I just noticed is that the stats that the Skritter app shows aren't consistent with what the site shows.
For example, I just did 100 tone reviews while working through my queue with "tones only". The app shows that I studied 189 character tones and 77 word tones. Neither of these two numbers are close to 100, so I guess the app and the site aren't too consistent in this regard. It would be easier to track things if they were consistent.
Basically, I suppose I can make a note everyday of how many tone reviews are due and then see what the number is at the end of the day and subtract to find how how many I've done, but then I'd have to do a daily math review as well. It would be cool if this were simpler
