Verdict
The clearest difference is rating: KeeNotes at 5.0 against Scan Things's 3.9. KeeNotes also leads on update cadence (every 9 days vs every 6 weeks) and iOS requirement (15.0 vs 17.6). Scan Things's advantage is monetization model (free vs freemium) and ratings volume (7 vs 1). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Scan Things sells 1 one-off in-app purchase and KeeNotes sells 1 in-app purchase, starting at $8.00 per year. Whichever you choose, the download price is not the number that matters.
KeeNotes holds the better App Store score, 5.0 against 3.9. That said, the two scores are not equally well evidenced: Scan Things has 7 ratings behind it against 1, so its average is the more settled of the two.
Scan Things ships an update every 6 weeks, KeeNotes every 9 days. The most recent releases landed on October 30, 2026 and October 28, 2026 respectively.
