The latest version of Nokia Sports Tracker has just been released (V 3.02). I tried it on my N97 and it looks fantastic.
Here's a list of the major improvements I've noticed (in addition to existing features)
1. Improved startup screen shows:
latest workout,
sunrise & sunset details.
2. Main display shows:
better, clearer maps (Open Street Map)
Speed & Average
HR & Average
Elapsed & Actual Time
Latitude / Longitude
3. Detailed screen shows:
"Speed -vs- avg"
"Speed last km"
4. Workout summary shows:
Map and Summary on same page
Energy consumed (seems a little on the high side)
5. GPS appears to lock on much quicker. Maps appear to display much quicker
6. New version installs alongside old version (instead of replacing it)
7. Calendar much easier to read. The N97 previously could only use a very old version of NST with a very difficult to read calendar. The new one is much easier to read and navigate.
These are my first impressions. I'm excited - it looks great. I'll let you know more after I've given it a bit of a workout.
