ReceptionRating · Positive reviews · Number of ratings

DEVONthink To Go 4 holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: DEVONthink To Go 4 has 257 ratings behind it against 20, so its average is the more settled of the two. Written reviews complicate that: 45% of DEVONthink To Go 4's written reviews are positive against 85% of Kan Do's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

DEVONthink To Go 4 ships an update every 3 weeks, Kan Do every 2 days. The most recent releases landed on October 30, 2026 and November 1, 2026 respectively.
