VHail Driver is the driver app for the VHail system. Taxi and limo drivers can download this app to receive ride requests from users of the VHail app. Drivers can use this service for free at the current time.
If you have not been invited to user VHail Driver, you should not download this app. Drivers can create an account through this app, but they currently must provide an invitation token that is issued from an administrator of the VHail system.
VHail Driver uses GPS in order to inform the VHail system where the driver is in order to supply him/her with ride invitations. Continued use of GPS running in the background can dramatically decrease battery life.
