Unreliable
The idea is great in theory, but the app is incapable of locating you accurately and often changes directions when it thinks you are off course. The map is unreadable unless you are connected to wifi (which is when you would need an app like this) and the turn by turn directions are always too late. I tested out on a few routes I knew by heart, and I can guarantee you I would not have made it. Even the search for locations is unreliable and will often take you someplace you dont want to go.
All in all, I would love this app if it worked and maybe it will in the future, but right now, stick to Google Maps.
