The Good Scout
 automatically alerts you to bad traffic on your commute. It includes a 
points-of interest database, a history list, and syncs with a website 
for saved destinations. The basic app is free.
The Bad You have to pay a fee to download maps in Scout. It does not include routes using public transit or bicycles.
The Bottom Line Scout
 offers a better feature set, including excellent help for daily 
commuters, than either Google Maps or Apple Maps, with similarly good 
route guidance.
