# NoiseLevel vs Custom Roulette

The clearest difference is price: Custom Roulette at Free against NoiseLevel's $0.99. Custom Roulette also leads on rating (3.7 vs 2.6). NoiseLevel's advantage is ads (none vs shown) and update cadence (fortnightly vs every 30 months). On review sentiment, in-app purchases and device support there is nothing between them.

Custom Roulette is free to download; NoiseLevel costs $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Custom Roulette holds the better App Store score, 3.7 against 2.6. That said, the two scores are not equally well evidenced: NoiseLevel has 28 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 56% of NoiseLevel's written reviews are positive against 50% of Custom Roulette's, so the app with the better star average is not the one people write more warmly about.

NoiseLevel ships an update fortnightly, Custom Roulette every 30 months. The most recent releases landed on September 26, 2026 and June 8, 2026 respectively.
