FRC Abacus is an alliance selection and eliminations companion. During alliance selection, one simply picks the teams that have been picked (in order), and they are sorted into their proper alliance. Then, during eliminations, one can use the app to double-check the alliances, and who plays who in the quarterfinals and beyond. Alliances can also be shared/exported through the top-right button. A little bit of lag is to be expected after installation, but then the app will be ready to go!
The app currently just has the 2013 IRI team list, ready for Saturday afternoon!
If anyone has any private quesitons, comments, or bug reports, feel free talk to me at the 2013 IRI (I will be volunteering as the IRI video archiver), or email me (kenavt at gmail dot com).
