I did a quick look at download statistics for MathTerms at iTunes, Amazon and Barnes and Noble. I was way surprised! I expected many downloads for iPad and not so much for Android. Turns out that Barnes and Noble Nook users downloaded it over 5,000 times in December and over 25,000 times in the the last 5 months. These numbers are very comparable to iPad installs. Amazon Appstore installs were way behind the others.
I hope you find the MathTerms app useful. While I do not have any immediate plans for an update, I welcome comments and suggestions
