Pearl Bids is built in FileMaker (MAC/WIN), an enterprise level Database tool. As such it can be networked.*
If you have FileMaker Pro 12 (even the trial version is fine) or FileMaker Server 12, you can open the Pearl Bids database file in FileMaker. Lots of schools already have aFileMaker sitewide license, so ask around. Once opened you can share Pearl Bids with other FileMaker users or on an iPad.
