As known many speedo readings are inaccurate and can be at a slightly lower speed than read. 

On motorcycles forum someone said I could do a GPS with my phone if so can one of you tech gurus here tell me how to do it in easy non-technical language.

Thanks. 

 

Google Maps?

Not sure whether I got it right:

you want to use GPS to measure actual speed?

Not so much interested in route planning/map?

There is a multitude of apps for reading GPS data which incl. location, time, speed, direction.

On my Android phone I use "GPS Test" from "Chartross Limited".

As my chair stands still, not much to see right now

 

Up here there are still roads so quiet you can drive from milestone to milestone (1 km actually) and (stop)watch the time.

Drive 80 km/h shown by speedo, drive 1 km, 45s would be exactly 80 km/h.

(1 min = 60 km/h)

After having changed tire size on my car it is quite accurate and not "allowed/desired":

showing higher than actual speed is the rule/law in Germany and maybe other countries (like 7%).

Watch from app's store there is many kind to use. And you find what is best for you.

Thanks I guess I ask for help because on motorcycles forum they reckon you can check how accurate your speedometer reading is.

Thanks again I guess that is something I can do if I got someone good with a stopwatch. 

The problem as I see it is pressing a phone screen to get readings I don't see how they do it on there own.
