Verdict

The call

The clearest difference is price: ElbowCalc at Free against Screw Flight Pro's $3.99. ElbowCalc also leads on update cadence (every 5 weeks vs every 41 months) and iOS requirement (13.0 vs 16.1). Screw Flight Pro's advantage is in-app purchases (none vs 1). On ads and device support there is nothing between them.
