# Echo vs Recall Detective

The clearest difference is in-app purchases: Echo at none against Recall Detective's 3. Echo also leads on rating (5.0 vs 4.6). Recall Detective's advantage is ratings volume (13 vs 1) and iOS requirement (15.1 vs 17.0). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Recall Detective sells 3 one-off in-app purchases. Echo asks for nothing beyond the download.

Echo holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Recall Detective has 13 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, Recall Detective fortnightly. The most recent releases landed on September 11, 2026 and September 13, 2026 respectively.
