On mobile phone however, the interface is goofy. It asks that users "use two fingers" to browse the map, and then a single tap drops a pin. This is a problem because as users try to browse the map, it suddenly drops 3 pins on the map on top of each other, and just doesn't work well.
So the scope is to make moving around the map easier, and not drop pins by moving around and zooming in. And also make double-tap drop a pin instead of the single tap like it is now.
