Verdict

The call

The clearest difference is price: mechanical design engine at Free against Tank Partial Volume Calculator's $2.99. mechanical design engine also leads on update cadence (every 2 months vs every 56 months) and iOS requirement (13.0 vs 16.1). On ads, in-app purchases and device support there is nothing between them.
