This app is a serious one... previously all other apps had pathetic accuracy, but this one is really good.
- I have read on the net that our hand held phones are capable of an avg 20M accuracy...
Some older phones and older apps would show much poor results.
I myself have fair faith in the results from this app as compare to cheap speedometers... my old Cd70 used to show 115kmph and I was extremely excited about it , some time ago... now that speedo is dead 
So u can't exactly believe on cheap bikes and their speedos...
Speed guns and GPS is the more accurate way..
