Verdict

The call

The clearest difference is price: PDFAI Scan at Free against SoundNote Pro's $2.99. PDFAI Scan also leads on rating (5.0 vs 4.3) and review sentiment (50% vs 35%). SoundNote Pro's advantage is ratings volume (350 vs 7) and update cadence (every 9 days vs every 3 weeks). On ads, in-app purchases and iOS requirement there is nothing between them.
