Students at Duke University are gearing up to see which student team can build the next best app.

Starting at 6 p.m. today, teams in the “Big Byte Challenge” have 78 hours to build a prototype app that is compatible with the iOS platform. The three-person teams are comprised of undergraduate and graduate students. Apps must be submitted by 11:59 p.m. Sunday. After that, teams will have the opportunity to practice their demos before their three-minute pitch presentations start Monday at 7:30 p.m. The top teams could win prizes including MacBook Airs and iPad minis.

The competition is being hosted with support from AT&T and Apple.
