[Shrub]

Our team's school has iPads for every student, so we use the FRC Scout app. One of our mentors is the "master iPad", where is we compile data, and then 6 students donate theirs for the day (3 red and 3 blue). We compile all the Red data to Red 1, all the Blue data to Blue 1, and then all that to the "master" through Bluetooth. Sometimes we end up playing games on them, but there haven't any incidents where students snoop on things other students have on their iPads (and since there's no WiFi that isn't a huge possibility).

Of course, iPads are expensive, and at the least you would need 6 to scout. I prefer Android (like a certain scouting captain on my team) but I don't know if there's an app available for that besides FRC Spyder.
