Verdict
The clearest difference is monetization model: ExtCalc at free with in-app purchases against Bezel's subscription. ExtCalc also leads on device support (6 vs 3). Bezel's advantage is review sentiment (32% vs 0%) and update cadence (weekly vs every 5 months). On price, ads, in-app purchases and iOS requirement there is nothing between them.
