Ratings and Reviews
Helped me calibrate my speedometer
Some of you may know that auto manufacturers will set a "corrected" speed to show on your dash. This is often between 5-10% over your "true" speed which is displayed on those speed readers on the side of the road next to speed limit signs (AND this app). The likely reason for this is so you do not drive too fast by offering a buffer for your speed-demon.
This app allowed me to estimate the differential of my "true" speed and my "corrected" speed. I then took these estimations to adjust my speedometers on my Triumph Daytona 675R(+6%), Suzuki SV650(+7%), and BMW 335i(+7%) via the obd connections and speedohealer.
The only con I can think of is that apps like this will terminate any excuses of your speedometer not working for those of you riding with broken dashes (although RPMs and temps are a different story)
So, I was fidgeting in my car trying to figure out why my lighter wouldn't work when I discovered the lighter port wasn't connect. "Oh", I thought, "I'll just plug that wire back in and it'll work!" So I did, I turned the car on, tried to charge my phone, and I heard an electrical discharge inside the dash. Apparently I fried out the entire instrument cluster leaving me with no speedometer. Thankfully we live in the future and we can just download one on our phones now. This app works great, and is very accurate. I know because when I drive past those signs that show you your speed, it says the same thing the app does. Pretty cool stuff. Not sure how it happens, obviously some sort of witchcraft that the developer summoned in a seance. Now if only they made an app for my gas gauge.
Unsure how to assess its accuracy
I have a Prius. Checking it against those road-side police boxes, I figured it was reporting about 1 mph high. Speed Box also suggests that the Prius speedometer is reporting high. But the app isn't consistently different. With the Prius at 70, Speed Box varies between 66 and 69. As the car changes speed, so does the app but at a different rate. So I don't quite know how to assess what is going on. The precision is only to the nearest mph anyhow so if the car rounds up and the app rounds down, differences are to be expected. Plus who knows what the Prius technology is anyhow- calculated or measured - sometimes it feels like the car speed is fluctuating while the display remains constant. Some damping or hysteresis in either or both of these possibly?
It would definitely beat a broken speedometer but I would say don't depend on it for an exact instantaneous speed.
