I used to use Trace, which I quite liked because it showed your trail maps and colored your path depending on how fast you were going at any given point (red = the place I fell down and had to stop to put a ski back on!). I didn't like it because it doesn't hook up to my iPhone health app and seems to drain my battery. So this year I decided to test Slopes and I like it - it syncs to the health app and is much kinder on the battery. It doesn't do the cool colors for speed, but overall I agree that the free version is really more than sufficient, and I think it'll be my app of choice moving forward.
Glad to hear another positive review for Slopes! Stinks that Trace had the less favorable aspects because the speed colors sounds pretty cool!
