# Scan to PDF vs iDocument Scanner

The clearest difference is review sentiment: iDocument Scanner at 100% against Scan to PDF's 48%. iDocument Scanner also leads on in-app purchases (none vs 11) and device support (3 vs 1). Scan to PDF's advantage is rating (4.7 vs 4.2) and ads (none vs shown). On price and update cadence there is nothing between them.

Both are free to download. Scan to PDF sells 10 in-app purchases, starting at $3.99 per month. iDocument Scanner asks for nothing beyond the download.

Scan to PDF holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: Scan to PDF has 24K ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 48% of Scan to PDF's written reviews are positive against 100% of iDocument Scanner's, so the app with the better star average is not the one people write more warmly about.

Scan to PDF ships an update every 2 months, iDocument Scanner every 3 months. The most recent releases landed on October 17, 2026 and October 2, 2026 respectively.
