Verdict

The call

The clearest difference is price: Column Construction Calculator at $1.99 against CombinedFooting's $14.99. CombinedFooting's advantage is update cadence (every 3 weeks vs every 38 months) and chart position (#132 vs unranked). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
