Verdict

The call

The clearest difference is ads: Files at none against Calc Pro HD's shown. Files also leads on device support (3 vs 1) and iOS requirement (5.0 vs 9.0). Calc Pro HD's advantage is rating (4.7 vs 4.4) and ratings volume (1.5K vs 242). On price, review sentiment, update cadence and in-app purchases there is nothing between them.
