# Digit Matrix vs Domino Gear

The clearest difference is review sentiment: Digit Matrix at 100% against Domino Gear's 0%. Digit Matrix also leads on ratings volume (6 vs 2). Domino Gear's advantage is rating (5.0 vs 3.8) and iOS requirement (9.0 vs 15.6). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Digit Matrix sells 6 one-off in-app purchases and Domino Gear sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Domino Gear holds the better App Store score, 5.0 against 3.8. Both are backed by a comparable volume of ratings — 6 and 2 respectively. Written reviews complicate that: 100% of Digit Matrix's written reviews are positive against 0% of Domino Gear's, so the app with the better star average is not the one people write more warmly about.

Digit Matrix ships an update every 3 weeks, Domino Gear fortnightly. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
