Verdict

The call

The clearest difference is in-app purchases: PDF Scanner Pro at none against Translator's 6. PDF Scanner Pro also leads on ads (none vs shown) and iOS requirement (14.0 vs 16.0). Translator's advantage is ratings volume (667 vs 23) and rating (4.4 vs 4.2). On price, review sentiment, update cadence and device support there is nothing between them.
