Verdict
The clearest difference is rating: Convert at 4.7 against Unit Converter Simple's 4.0. Convert also leads on ratings volume (126 vs 1) and update cadence (every 3 months vs every 10 months). Unit Converter Simple's advantage is in-app purchases (none vs 2). On price, ads, device support and iOS requirement there is nothing between them.
