Verdict
The clearest difference is in-app purchases: RedbackINSTALL at none against Crosswind Calculator's 1. RedbackINSTALL also leads on ads (none vs shown) and iOS requirement (10.1 vs 18.0). Crosswind Calculator's advantage is update cadence (weekly vs every 6 weeks). On price and device support there is nothing between them.
