Verdict
The clearest difference is rating: iGanttChart at 4.0 against Building Tools's 1.0. iGanttChart also leads on monetization model (freemium vs subscription) and ratings volume (23 vs 2). Building Tools's advantage is review sentiment (100% vs 60%). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. iGanttChart sells 2 in-app purchases, starting at $2.99 per month and Building Tools sells 4 in-app purchases, starting at $16.49 per month. Whichever you choose, the download price is not the number that matters.
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.
iGanttChart ships an update every 2 weeks, Building Tools fortnightly. The most recent releases landed on September 22, 2026 and August 14, 2026 respectively.
