# Invoice Maker・Estimate App vs PDF Scanner | Document Scan

The clearest difference is rating: Invoice Maker・Estimate App at 4.9 against PDF Scanner | Document Scan's 4.5. PDF Scanner | Document Scan's advantage is review sentiment (82% vs 67%) and ratings volume (1.9K vs 201). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Invoice Maker・Estimate App sells 4 in-app purchases, starting at $5.99 per 7 days and PDF Scanner | Document Scan sells 2 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

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.

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.
