Verdict
The clearest difference is price: E3 Safety at Free against CheckOut Master's $1.00. E3 Safety also leads on ratings volume (41 vs 1) and iOS requirement (15.1 vs 18.0). CheckOut Master's advantage is rating (5.0 vs 4.5) and update cadence (every 2 days vs every 9 days). On ads, in-app purchases and device support there is nothing between them.
