# PDS vs Proofreader

The clearest difference is rating: PDS at 5.0 against Proofreader's 4.3. PDS also leads on in-app purchases (none vs 2) and ads (none vs shown). Proofreader's advantage is ratings volume (19 vs 1). On price, update cadence and device support there is nothing between them.

Both are free to download. Proofreader sells 2 in-app purchases, starting at $9.99 per month. PDS asks for nothing beyond the download.

PDS holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Proofreader has 19 ratings behind it against 1, so its average is the more settled of the two.

PDS ships an update every 2 months, Proofreader every 3 months. Both last shipped on October 3, 2026.
