Verdict
The clearest difference is price: ScanPDF at Free against Memo Search's $1.99. ScanPDF also leads on update cadence (every 6 weeks vs every 23 months). Memo Search's advantage is ads (none vs shown) and iOS requirement (15.6 vs 26.0). On in-app purchases and device support there is nothing between them.
