Verdict
The clearest difference is price: QRCoder at Free against Aspect Ratio Pro's $3.99. QRCoder also leads on rating (5.0 vs 4.0) and ratings volume (6 vs 1). Aspect Ratio Pro's advantage is in-app purchases (none vs 1) and update cadence (every 3 weeks vs every 2 months). On review sentiment, ads, device support and iOS requirement there is nothing between them.
