Verdict
The clearest difference is in-app purchases: OpenNutriTracker at none against SnapCal's 1. OpenNutriTracker also leads on device support (3 vs 1) and iOS requirement (15.5 vs 17.0). SnapCal's advantage is update cadence (every 2 days vs monthly). On price and ads there is nothing between them.
