If you’ve ever tried to adjust your GPS settings while you’re driving, you know it can be tricky and highly dangerous. We can handle a stick shift while drinking a coffee and eating a Egg McMuffin, but leaning over to tap a screen through menus can take our eyes of the road a bit too long. It’s the reason we haven’t been fans of most speedometer apps we’ve come across. SpeedGlow is different, allowing you to control everything with gesture controls instead of menus. Quick swipes and taps are all you need to view more details, change your speed limit alarm (probably a feature you won’t use) and access the heads up display so you can reflect the display onto your windshield at night. Now you can really track your Prius’ 0-60 time.
