# Echo vs 闹钟实验室

The clearest difference is update cadence: Echo at every 4 days against 闹钟实验室's every 9 days. Echo also leads on iOS requirement (18.0 vs 26.0). 闹钟实验室's advantage is ratings volume (10 vs 2). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Echo sells 1 one-off in-app purchase and 闹钟实验室 sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for Echo against 5.0 for 闹钟实验室. That said, the two scores are not equally well evidenced: 闹钟实验室 has 10 ratings behind it against 2, 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 4 days, 闹钟实验室 every 9 days. The most recent releases landed on September 30, 2026 and October 5, 2026 respectively.
