Verdict
The clearest difference is rating: Lutron App at 4.8 against Flex's 3.0. Lutron App also leads on ratings volume (6.7K vs 4) and update cadence (every 9 days vs every 6 weeks). Flex's advantage is monetization model (free vs ad-supported) and iOS requirement (9.3 vs 16.6). On price, ads, in-app purchases and device support there is nothing between them.
