Dash is similar to Automatic, using Bluetooth and a connection to the OBD-II port to gather driving information and make suggestions. Automatic, however, currently only works with iPhone(Android coming soon) while Dash works with Android and will be available for iPhone in the future.
Automatic‘s smart driving assistant that connects to the OBII port on cars and iOS devices is being updated with iBeacon functionality.
iBeacon is a feature in Bluetooth 4 ant allows devices near each other share information. For example, iBeacons in Apple Stores are used to share information with customers.
