OnTime is an "Exact Time of Arrival (ExTA)" app which should not be confused with "Estimated Time of Arrival (ETA)."

This app is designed to give you a real-time, realistic and exact time of arrival based on your travel speed (Not "Estimated").

On Time is not a navigation system app, live traffic, direction or a map view guide. The app core functionality is to calculate ExTA based on how fast you are travelling. On Time will tell you the time remaining before you reach your destination.

Use OnTime if you are travelling in public transportation like trains, buses or trams. Never use OnTime if you are driving.
