I use this app when my taxi driver has no idea where my school is. The accuracy is relatively good for China. Just be aware that the map is only functional within China. On a recent trip to Pingxiang along the Vietnamese border, the map just vanished as if nothing was there. Then I compared to Apple Map and found that the roads only extended to the border. Other than that minor glitch this has served me well. Only functions in Chinese though. It would be good to have a multilingual menu option in future editions.
