# EchoRef vs CSWG App

The clearest difference is update cadence: CSWG App at every 5 days against EchoRef's every 2 months. CSWG App also leads on iOS requirement (16.0 vs 26.0). EchoRef's advantage is ratings volume (1.4K vs 13). 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.

On the App Store both sit at effectively the same score — 4.9 for EchoRef against 5.0 for CSWG App. That said, the two scores are not equally well evidenced: EchoRef has 1.4K ratings behind it against 13, so its average is the more settled of the two.

EchoRef ships an update every 2 months, CSWG App every 5 days. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
