Bummer on Trace . . . used that for years and it remained my favorite, even though the company totally abandoned it (they seem to focus on soccer now).
The best part about it was you could record on phone and then view on browser - so full size.
I was able to change my password and log into site, but couldn't log into app. Maybe they didn't update for iOS 14? It's not available in app store.
Anyway, Ski Tracks has served me pretty well.
Another I've used, but not paid version is Slopes. It seems to have a lot of nice features and displays. Worth having a look at at least.
BTW, if you have Trace data you can download it from the website in GPX files. I just downloaded everything . . . (I hope!)
