Verdict
The clearest difference is rating: Unit Converter Max at 5.0 against Optio's 3.0. Unit Converter Max also leads on monetization model (free vs freemium) and ratings volume (26 vs 2). Optio's advantage is update cadence (every 9 days vs every 3 weeks). On price, ads, in-app purchases and device support there is nothing between them.
