MathTerms was written using Appcelerator Titanium so that I could deploy on iOS devices or Android devices. It does need substantial screen real estate, however, to see graphics and text — i.e. is really designed for tablets.
Amazon has finally announced the Kindle Fire. I am in the process of porting to Android. As Amazon hasn’t disclosed too much info to developers at this point, I can’t be sure of Android version and API level. This should be disclosed in the next week or two.
Of course, this does not mean Amazon will accept the app into their app store! I *will* submit as soon as possible — and we’ll see 😉
