Verdict
The clearest difference is price: AvID at Free against FireOps Calc's $1.99. AvID also leads on ratings volume (25 vs 2) and iOS requirement (12.0 vs 15.1). FireOps Calc's advantage is rating (5.0 vs 4.1) and in-app purchases (none vs 2). On ads and device support there is nothing between them.
