Speed Overlay is currently being actively developed. If you encounter a problem, please consider using the Email Developer link below rather than just leaving a low rating, that way I can attempt to resolve the problem for you ASAP.
Caveats:The average speed calculation is currently very simple. I'm looking at improved algorithms. Currently the options are.Average of Doppler instantaneous velocities. Fine if your GPS chip provides very regular updates, and the more accurate Distance Over Time, which is prone to some variation of distance due to GPS jitter. Both will be more accurate in motorway driving than city driving - so just fine for keeping an eye on those annoying average speed camera zones on the motorway.
