# Challenge vs Stack Champs

The clearest difference is in-app purchases: Challenge at none against Stack Champs's 8. Challenge also leads on ratings volume (32 vs 1) and iOS requirement (11.0 vs 15.0). Stack Champs's advantage is update cadence (fortnightly vs every 4 months) and rating (5.0 vs 4.8). On price, ads and device support there is nothing between them.

Both are free to download. Stack Champs sells 7 one-off in-app purchases. Challenge asks for nothing beyond the download.

Stack Champs holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Challenge has 32 ratings behind it against 1, so its average is the more settled of the two.

Challenge ships an update every 4 months, Stack Champs fortnightly. The most recent releases landed on October 15, 2026 and October 6, 2026 respectively.
