TrackRec v1.01 with faster drawing and more robust track saving is now available in App Store, so get it while it's hot :p ... Here's a link to the application page.

This version should solve many of the problems reported related to track saving, which basically was too slow when the application was quitting.

A new version (v1.01) of TrackRec was submitted for review today and will hopefully show up in App Store soon. It contains optimizations for faster track drawing on maps and more robust track saving. Saved tracks will also take up significantly less space with the new update.
