# EchoRef vs Emergency Manual

The clearest difference is ratings volume: EchoRef at 1.4K against Emergency Manual's 12. Emergency Manual's advantage is iOS requirement (16.0 vs 26.0). On price, rating, review sentiment and ads 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 Emergency Manual. That said, the two scores are not equally well evidenced: EchoRef has 1.4K ratings behind it against 12, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
