Speedy - Speedometer

I tried VBox, I tried Dragy, both of those options are costly This app is very simple to use, has accurate results. Definitely would recommend. Make you sure you have strong GPS signal first before measuring your acceleration times!

I caught this app while they run a promotion to download it for free. Very happy with that. Opened the app, made an account quick and easy no extra stuff. I have Vbox tool and I decided to compare results from Speedy and Vbox. I was shocked, I run 5 times and results were absolutely same! Wow that's crazy, I tried many other apps and they are way far from accuracy comparing to Vbox tool. Very happy with this app! Waiting for more updates Follow these guys on Instagram!

Speedometer is a bit laggy, but very accurate once your speed levels off. Takes a while to figure out that you’ve stopped. The auto 0-60, 0-100 and Quarter Mile automatically resets and restarts after every full stop (which takes about 30-40 seconds for the App to recognize), which is a nice feature, but unfortunately the 0-60 timer is useless for any vehicle that can accelerate from 0-60 in less than 8 seconds. It just can’t keep up.

Not sure why but I can’t get it to stay on 0 it bounces between .3 and .6

My Tesla Model 3 is rated as a 4.4 sec 0-60 car and its ready 12 seconds. Also I slowed down at 101 mph yet the app only measures me at 93 mph. I had full GPS bars. I think this is because of the limitation of my iphone Xr GPS component. Just not equipped for fast acceleration. Since this is free and requires registration. It seems that we are the product here.
