# Brilliant vs Sets Challenge

The clearest difference is review sentiment: Brilliant at 79% against Sets Challenge's 33%. Brilliant also leads on update cadence (weekly vs every 4 months) and ratings volume (33K vs 2). Sets Challenge's advantage is in-app purchases (none vs 19) and ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. Brilliant sells 16 in-app purchases, starting at $19.99 per month. Sets Challenge asks for nothing beyond the download.

Sets Challenge holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Brilliant has 33K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 79% of Brilliant'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.

Brilliant ships an update weekly, Sets Challenge every 4 months. The most recent releases landed on September 30, 2026 and September 17, 2026 respectively.
