Wow, what a ride. We thought we had this one ready at Magic Live, then attendees gave us some excellent notes. After everything was built-in we were hit by some major new android requirements from google and then finally we were rejected from the apple app store because they were not fans of our app name.
We made it! Thanks for your patience. Here is calculator mode. It's a big new input mode for the NKTW app. Below are three videos, these include a performance, a presentation discussion and technical app overview. Enjoy!
