# 3CX vs IRIS Alert

The clearest difference is rating: IRIS Alert at 4.0 against 3CX's 2.6. 3CX's advantage is review sentiment (28% vs 0%) and ratings volume (321 vs 4). On price, ads, in-app purchases and monetization model there is nothing between them.

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

IRIS Alert holds the better App Store score, 4.0 against 2.6. That said, the two scores are not equally well evidenced: 3CX has 321 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 28% of 3CX's written reviews are positive against 0% of IRIS Alert's, so the app with the better star average is not the one people write more warmly about.

3CX ships an update monthly, IRIS Alert every 3 months. The most recent releases landed on October 22, 2026 and October 9, 2026 respectively.
