ReceptionRating · Positive reviews · Number of ratings

iGanttChart holds the better App Store score, 4.0 against 1.0. That said, the two scores are not equally well evidenced: iGanttChart has 23 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 60% of iGanttChart's written reviews are positive against 100% of Building Tools's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

iGanttChart ships an update every 2 weeks, Building Tools fortnightly. The most recent releases landed on September 22, 2026 and August 14, 2026 respectively.
