Good for MPH.
It’s great if you need to know your speed or what road you’re on. The gps map is accurate but to small and hard to read. Odometer is way off. I’ve checked and verified distances with Garmin GPS and Google maps. The app says traveled 23 miles when I’ve actually only traveled 11 miles. So if you just need speed this is a good one. If you’re trying to keep track of MPG or your mileage, pass this app up.
