Absolutely no reason to use it over Google UNLESS...

I dont get it. Why would I want to use this? No satellite view. Supposedly a street view, but I have no idea how to use it. If you absolutely need a map offline (why would you???) than this is the app for you. Otherwise sorry Navmii, but I have to recommend Google!...UNLESS you are in a commercial truck. I havent verified this completely - only tested on one trip, but it appears to know truck routes. Around my house are some back roads you wouldnt want to take in a big rig. Google recommends those roads, but this app when I changed it to transport truck didnt suggest any of the roads Google did. That is huge.
