# Brushlink vs GUM SMART

The clearest difference is review sentiment: Brushlink at 100% against GUM SMART's 41%. Brushlink also leads on in-app purchases (none vs 1). GUM SMART's advantage is rating (4.8 vs 3.3). On price, ratings volume, update cadence and ads there is nothing between them.

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

GUM SMART holds the better App Store score, 4.8 against 3.3. Both are backed by a comparable volume of ratings — 3 and 4 respectively. Written reviews complicate that: 100% of Brushlink'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.
