Verdict
The clearest difference is rating: Sheet Music Scanner at 4.5 against Windy's 4.0. Sheet Music Scanner also leads on ratings volume (6.5K vs 40) and chart position (#144 vs unranked). Windy's advantage is monetization model (free with in-app purchases vs subscription) and iOS requirement (11.3 vs 15.0). On price, update cadence, ads and in-app purchases there is nothing between them.
