# 书影迹 vs the waterfall

The clearest difference is update cadence: 书影迹 at weekly against the waterfall's every 3 months. 书影迹 also leads on iOS requirement (13.0 vs 18.0). the waterfall's advantage is ratings volume (5 vs 1). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. 书影迹 sells 6 in-app purchases, starting at $0.99 per month and the waterfall sells 1 one-off in-app purchase. 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 书影迹 against 5.0 for the waterfall. That said, the two scores are not equally well evidenced: the waterfall has 5 ratings behind it against 1, so its average is the more settled of the two.

书影迹 ships an update weekly, the waterfall every 3 months. Both last shipped on November 3, 2026.
