# One Scan vs Document Scanner

One Scan and Document Scanner both sit at 4.7 stars, but that hides the real split: 90% of Document Scanner's written reviews are positive against 26% of One Scan's. Document Scanner also leads on update cadence (every 2 weeks vs every 2 months) and iOS requirement (18.0 vs 26.0). One Scan's advantage is ratings volume (12K vs 556).

Both are free to download. One Scan sells 10 in-app purchases, starting at $3.99 per 7 days and Document Scanner sells 4 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.
