# Intelligence Test vs SUM

The clearest difference is update cadence: SUM at every 3 days against Intelligence Test's every 5 months. Intelligence Test's advantage is iOS requirement (12.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Intelligence Test sells 1 one-off in-app purchase and SUM sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Intelligence Test ships an update every 5 months, SUM every 3 days. The most recent releases landed on October 1, 2026 and October 2, 2026 respectively.
