ReceptionRating · Positive reviews · Number of ratings

Invoice Maker・Estimate App holds the better App Store score, 4.9 against 4.5. That said, the two scores are not equally well evidenced: PDF Scanner | Document Scan has 1.9K ratings behind it against 201, so its average is the more settled of the two. Written reviews complicate that: 67% of Invoice Maker・Estimate App's written reviews are positive against 82% of PDF Scanner | Document Scan's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Invoice Maker・Estimate App ships an update every 3 days, PDF Scanner | Document Scan every 5 days. The most recent releases landed on October 17, 2026 and October 16, 2026 respectively.
