Zuby HUD

Nice simple speedometer with the ability to flip mirror image to allow use as a headup display where the phone is viewed reflected in the windshield The display looks clean in KPH mode However in MPH mode the dial is left the same all that happens is that the markings at 30 60 90 120 150 and 180 KPH are replaced by the corresponding values in MPH eg 18 36 54 72 90 and 108 MPH So getting a speed in MPH from the dial will involve a lot of mental gymnastics Probably easier to keep in KPH and then convert at the end So for us folks in nonmetric parts of the world there is at least one this app is not very useful Also in my case the phone locks as it usually does meaning if you were to use it as a HUD in your car it would lock up after a few minuts of driving and stop displaying anything Other speedo apps can if set up that way lock out the feature and stay on indefinately           Nice and simple but MPH is not well supported

It would be better if you can change the increments of the maximum speed by 510 kphmph instead of 3216 and add speed limit with a warning tone Other than that for as simple as it is its pretty accurate once it finds good signal and u move more than 10mph           Simple but
