# U vs Napa PROTracker

The clearest difference is rating: Napa PROTracker at 3.5 against U's 1.9. Napa PROTracker also leads on in-app purchases (none vs 10) and review sentiment (43% vs 11%). U's advantage is ratings volume (125 vs 13) and iOS requirement (8.0 vs 15.6). On price, ads and device support there is nothing between them.
