Verdict
The clearest difference is review sentiment: ReStretch at 80% against The Flex's 43%. ReStretch also leads on rating (5.0 vs 4.8). The Flex's advantage is update cadence (every 3 weeks vs every 6 weeks) and ratings volume (33 vs 5). On price, ads, in-app purchases and monetization model there is nothing between them.
