Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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