Verdict

The call

The clearest difference is rating: Duet Air at 4.3 against BeMyDisplay's 3.0. Duet Air also leads on ratings volume (1.9K vs 1) and update cadence (every 3 weeks vs every 4 months). BeMyDisplay's advantage is monetization model (free with in-app purchases vs subscription). On price, ads, in-app purchases and device support there is nothing between them.
