# Brush DJ vs GUM SMART

The clearest difference is review sentiment: Brush DJ at 77% against GUM SMART's 41%. Brush DJ also leads on in-app purchases (none vs 1) and ratings volume (2.2K vs 4). GUM SMART's advantage is rating (4.8 vs 4.6). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. GUM SMART sells 1 in-app purchase, starting at $27.49 per year. Brush DJ asks for nothing beyond the download.

GUM SMART holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Brush DJ has 2.2K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 77% of Brush DJ's written reviews are positive against 41% of GUM SMART's, so the app with the better star average is not the one people write more warmly about.

Brush DJ ships an update every 3 months, GUM SMART every 2 months. The most recent releases landed on October 16, 2026 and October 15, 2026 respectively.
