ReceptionRating · Positive reviews · Number of ratings

Block Fortress holds the better App Store score, 4.6 against 3.1. That said, the two scores are not equally well evidenced: Block Fortress has 1.4K ratings behind it against 15, so its average is the more settled of the two. Written reviews complicate that: 82% of Block Fortress's written reviews are positive against 100% of Construct Up's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Block Fortress ships an update every 2 months, Construct Up every 2 weeks. The most recent releases landed on November 1, 2026 and October 20, 2026 respectively.
