RideMap shows you where the passengers are calling for rides in your city, helps you navigate there, and automates the process with a single button. One button displays a heat map of current demand, with other drivers’ positions. Long-press on a good location and your navigation app sets a path to it. The other button bypasses the map for you, calculates the nearest edge of the demanding surface and auto-navigates you there.

We have developed this app in both ios and android.
