Verdict

The call

The clearest difference is review sentiment: Calculator at 100% against Flex Scanner's 33%. Calculator also leads on rating (5.0 vs 4.5) and iOS requirement (12.0 vs 15.0). Flex Scanner's advantage is update cadence (every 9 days vs every 3 weeks) and ratings volume (24 vs 4). On price, ads, in-app purchases and monetization model there is nothing between them.
