Verdict

The call

The clearest difference is ratings volume: Scanner at 2.3K against PDF Scanner's 28. Scanner also leads on rating (4.8 vs 4.5) and update cadence (every 5 weeks vs every 2 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Scanner sells 10 in-app purchases, starting at $0.99 per 7 days and PDF Scanner sells 3 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.
