Otto is a smart new app for college carpooling. We connect members for friendly, low-cost transportation, leaving now or later, one-time or every day. A .edu email address is required for registration, and the address must be verified by responding to an email. There are extensive additional identification features, including photo-required trip check-ins, feedback, and optional Facebook profiles. Connections for preplanned transportation are also available with eRideShare.com members. The app handles communications but not payments, so payment arrangements are between the parties. From eRideShare Inc., the pioneer of online carpooling.
