# Echo vs Demod

The clearest difference is price: Echo at Free against Demod's $9.99. Echo also leads on ratings volume (36 vs 6). Demod's advantage is in-app purchases (none vs 2) and chart position (#119 vs unranked). On rating, review sentiment, update cadence and ads there is nothing between them.

Echo is free to download; Demod costs $9.99 up front. Echo sells 2 in-app purchases, starting at $4.99 per month. Demod asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.9 for Echo against 5.0 for Demod. That said, the two scores are not equally well evidenced: Echo has 36 ratings behind it against 6, 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 9 days, Demod fortnightly. Both last shipped on October 31, 2026.
