Verdict
The clearest difference is price: Elbow at Free against Screw Flight Pro's $3.99. Elbow also leads on update cadence (every 4 months vs every 41 months) and iOS requirement (13.0 vs 16.1). Screw Flight Pro's advantage is in-app purchases (none vs 2). On review sentiment, ads and device support there is nothing between them.
