# Fast Scanner vs iDocument Scanner

The clearest difference is rating: Fast Scanner at 4.8 against iDocument Scanner's 4.2. Fast Scanner also leads on ratings volume (6.1K vs 5). iDocument Scanner's advantage is in-app purchases (none vs 1) and review sentiment (100% vs 91%). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. Fast Scanner sells 1 one-off in-app purchase. iDocument Scanner asks for nothing beyond the download.

Fast Scanner holds the better App Store score, 4.8 against 4.2. That said, the two scores are not equally well evidenced: Fast Scanner has 6.1K ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 91% of Fast Scanner'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.

Fast Scanner ships an update every 2 months, iDocument Scanner every 3 months. The most recent releases landed on October 11, 2026 and October 2, 2026 respectively.
