Verdict
The clearest difference is rating: Arc+ at 4.6 against Arc Flash Label Calculator's 3.8. Arc+ also leads on ratings volume (113 vs 4). Arc Flash Label Calculator's advantage is update cadence (fortnightly vs every 4 months) and iOS requirement (9.0 vs 15.6). On price, review sentiment, ads and in-app purchases there is nothing between them.
