# PDF Scanner Pro vs Translator

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.

Both are free to download. Translator sells 6 in-app purchases, starting at $3.99 per 7 days. PDF Scanner Pro asks for nothing beyond the download.

Translator holds the better App Store score, 4.4 against 4.2. That said, the two scores are not equally well evidenced: Translator has 667 ratings behind it against 23, so its average is the more settled of the two. Written reviews point the same way: 25% of PDF Scanner Pro's written reviews are positive against 29% of Translator's.

PDF Scanner Pro ships an update every 2 weeks, Translator every 11 days. Both last shipped on November 7, 2026.
