# WolframAlpha vs Sets Challenge

The clearest difference is rating: Sets Challenge at 5.0 against WolframAlpha's 2.8. Sets Challenge also leads on in-app purchases (none vs 6) and iOS requirement (9.0 vs 17.6). WolframAlpha's advantage is ratings volume (129 vs 2). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. WolframAlpha sells 6 in-app purchases, starting at $9.99 per month. Sets Challenge asks for nothing beyond the download.

Sets Challenge holds the better App Store score, 5.0 against 2.8. That said, the two scores are not equally well evidenced: WolframAlpha has 129 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 35% of WolframAlpha's written reviews are positive against 33% of Sets Challenge's, so the app with the better star average is not the one people write more warmly about.

WolframAlpha ships an update every 2 months, Sets Challenge every 4 months. The most recent releases landed on September 25, 2026 and September 17, 2026 respectively.
