Verdict
The clearest difference is in-app purchases: Preston Cinema at none against DOT dataCalc's 2. Preston Cinema also leads on iOS requirement (13.0 vs 17.0). DOT dataCalc's advantage is update cadence (monthly vs every 4 months) and review sentiment (13% vs 0%). On price, ads and device support there is nothing between them.
