Great Free GPS-accurate speedo

A 1-trick Pony but a very useful trick none the less. From finding your cars speedo error to helping you maintain a ticket- free speed, it does the job simply and accurately. I use it often on trips setting cruise control, and by foot alone depending on what vehicle Im driving. Ads are unobtrusive and not an issue for me (and I am very Ad-intolerant). Recommended.
