I have complete the initial step of implementing a LAP TIMER functionality - before I am going to release this function officially I am looking forward to get some additional feedback.
The function is targeting people who are doing multiple laps (min 35 sec length) and want to keep track of each of the laps you are doing - it might not work on a 400m track & field lane - but should be working quite fine outdoors.
You can find this test-version of GPSLogger at:
http://www.emacberry.com/4support/GPSLogger.jad
this version supports all OS (so no nice SVG compass image for OS4.6 devices - this will come later)...
How to use the new Feature:
1) start logging
2) once you are at your lap start finish line:
open the menu and select "Set Start/Finish Line"
3) switch to Timing View to see new data:
current lap time / distance to start finish line (direct line)
once a lap is completed you will find an additional line:
lap length, lap time, average lap speed
Also once you save the path you will find the lap information in the PathDetails Popup
Let me know what you think
