# Boulder Challenge vs Spray

The clearest difference is review sentiment: Boulder Challenge at 71% against Spray's 0%. Boulder Challenge also leads on ratings volume (23 vs 2) and iOS requirement (10.3 vs 17.0). Spray's advantage is rating (5.0 vs 4.3) and update cadence (every 9 days vs every 6 weeks). On ads, in-app purchases, monetization model and device support there is nothing between them.

Boulder Challenge costs $2.99 and Spray $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Spray holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Boulder Challenge has 23 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 71% of Boulder Challenge's written reviews are positive against 0% of Spray's, so the app with the better star average is not the one people write more warmly about.

Boulder Challenge ships an update every 6 weeks, Spray every 9 days. The most recent releases landed on October 9, 2026 and October 15, 2026 respectively.
