# Echo vs Equ8

The clearest difference is in-app purchases: Echo at none against Equ8's 2. Echo also leads on update cadence (every 10 days vs every 3 weeks). Equ8's advantage is ratings volume (16 vs 1) and device support (3 vs 1). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Equ8 sells 2 in-app purchases, starting at $0.99 per month. Echo asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for Echo against 5.0 for Equ8. That said, the two scores are not equally well evidenced: Equ8 has 16 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

Echo ships an update every 10 days, Equ8 every 3 weeks. The most recent releases landed on October 15, 2026 and October 5, 2026 respectively.
