It seemed to be well-liked when it was in the android market (about 20k downloads and 4.7 / 5 rating).
A week shy of a year ago, the google play store yanked it on behalf of Rubik's for "trademark infringement". Curious, because the top rubik's cube apps are still full of apps actually using "Rubik" in the name while mine did not.
Anyhow, I've long since moved on (I originally wrote it in 16 hours, so not too invested), but recently some one suggested I just release the APK for anyone who really wants it to have. So here it is: NCube free download.
Also, If I'm not using XDA correctly, let me know. I'm new here.
Version 125: old UI with single-touch multi-touch modes, and circle menus.
Version 131: android-menu based UI with single mode optimized for multi-touch and supports up to 20x20x20 cubes.
