Lags – Navmii Offline GPS USA Review

Been using app for a week, and three issues: 1. The map lags; although it compensates by suddenly jumping to your current position. 2. Positioning is not always accurate, car icon occasionally jumps to the parallel street. 3. Location services for this app needs "while using" option. I have used other offline navigation apps for years, and this is not a good alternative (yet).
