When i switched to Android I assumed there was something like it out there but I haven't found anything.
BB Traffic would allow me to create favorite places and then when I clicked on them it would tell me how long it would take me to get there given the current traffic. It would also tell me what time I would be there. I could then text a person that information to let them know what time I would arrive. Was great to let my wife know when I left work.
With that information I knew whether I had to speed up a little bit or cruise. It would adjust to my speed and recalculate my arrival time.
I've tried Waze and that's more of an app to help you find alternate routes. BB Traffic did the same but also what I mentioned above.
