The app will be used by truck drivers driving to a warehouse. The core function is to indicate to the warehouse the ETA (Estimated Time of Arrival) by using the GPS of the truck driver‘s Safe Check-in app. When the truck driver is starting driving to the warehouse the ETA is frequently updated on his way with the help of phone GPS access and displayed to the warehouse. By this, the warehouse can better plan, when the truck will arrive to be loaded or unloaded.
