Verdict

The call

The clearest difference is rating: Scanner App at 5.0 against PDF Converter's 4.4. Scanner App also leads on monetization model (free with in-app purchases vs subscription) and review sentiment (100% vs 67%). PDF Converter's advantage is ads (none vs shown) and ratings volume (6K vs 1). On price, update cadence, in-app purchases and device support there is nothing between them.
