# QABA vs Triaj

The clearest difference is update cadence: Triaj at monthly against QABA's every 34 months. Triaj also leads on ratings volume (24 vs 3) and review sentiment (100% vs 92%). QABA's advantage is iOS requirement (12.0 vs 14.0). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

QABA holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Triaj has 24 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 92% of QABA's written reviews are positive against 100% of Triaj's, so the app with the better star average is not the one people write more warmly about.

QABA ships an update every 34 months, Triaj monthly. The most recent releases landed on October 5, 2026 and October 2, 2026 respectively.
