# Tetra Bus vs Island Sort

The clearest difference is update cadence: Tetra Bus at every 4 days against Island Sort's every 3 weeks. Tetra Bus also leads on rating (4.5 vs 4.3). On price, review sentiment, ratings volume and ads there is nothing between them.

Both are free to download. Tetra Bus sells 10 one-off in-app purchases and Island Sort sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Tetra Bus holds the better App Store score, 4.5 against 4.3. Both are backed by a comparable volume of ratings — 318 and 205 respectively. Written reviews complicate that: 24% of Tetra Bus's written reviews are positive against 31% of Island Sort's, so the app with the better star average is not the one people write more warmly about.

Tetra Bus ships an update every 4 days, Island Sort every 3 weeks. Both last shipped on October 30, 2026.
