# 达铃 vs 滚动字

The clearest difference is in-app purchases: 达铃 at none against 滚动字's 1. 达铃 also leads on iOS requirement (13.0 vs 16.0). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. 滚动字 sells 1 one-off in-app purchase. 达铃 asks for nothing beyond the download.

达铃 ships an update every 3 weeks, 滚动字 every 4 weeks. The most recent releases landed on October 25, 2026 and October 16, 2026 respectively.
