# 生辰 vs 瞳记

The clearest difference is in-app purchases: 瞳记 at none against 生辰's 7. 瞳记 also leads on review sentiment (86% vs 76%). 生辰's advantage is update cadence (every 3 weeks vs every 2 months). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. 生辰 sells 7 in-app purchases, starting at $1.99 per month. 瞳记 asks for nothing beyond the download.

生辰 ships an update every 3 weeks, 瞳记 every 2 months. The most recent releases landed on October 29, 2026 and October 28, 2026 respectively.
