ReceptionRating · Positive reviews · Number of ratings

Hour Blocks holds the better App Store score, 4.5 against 1.0. That said, the two scores are not equally well evidenced: Hour Blocks has 189 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 53% of Hour Blocks's written reviews are positive against 60% of Touch Annotator's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Hour Blocks ships an update every 4 days, Touch Annotator every 3 weeks. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
