Verdict
The clearest difference is in-app purchases: Barcode Notes at none against 上下求索's 5. Barcode Notes also leads on iOS requirement (13.0 vs 17.0). 上下求索's advantage is update cadence (every 2 months vs every 5 months). On price, review sentiment, ads and monetization model there is nothing between them.
