# One Scan vs PDF Scanner・Document Scanner・

The clearest difference is review sentiment: PDF Scanner・Document Scanner・ at 68% against One Scan's 26%. PDF Scanner・Document Scanner・ also leads on update cadence (fortnightly vs every 2 months) and iOS requirement (13.0 vs 26.0). One Scan's advantage is ads (none vs shown) and rating (4.7 vs 4.5).

Both are free to download. One Scan sells 10 in-app purchases, starting at $3.99 per 7 days and PDF Scanner・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.
