# Lost Echo vs Unsolved

The clearest difference is price: Unsolved at Free against Lost Echo's $4.49. Unsolved also leads on ratings volume (55K vs 86) and chart position (#41 vs unranked). Lost Echo's advantage is in-app purchases (none vs 12) and ads (none vs shown). On rating, review sentiment, update cadence and device support there is nothing between them.

Unsolved is free to download; Lost Echo costs $4.49 up front. Unsolved sells 11 one-off in-app purchases. Lost Echo asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.6 for Lost Echo against 4.7 for Unsolved. That said, the two scores are not equally well evidenced: Unsolved has 55K ratings behind it against 86, so its average is the more settled of the two. Written reviews are what separate them: 76% of Lost Echo's written reviews are positive against 71% of Unsolved's.

Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on September 26, 2026 and September 27, 2026 respectively.
