# 洛书 vs RSSBud

The clearest difference is review sentiment: 洛书 at 100% against RSSBud's 50%. 洛书 also leads on rating (5.0 vs 4.6). RSSBud's advantage is in-app purchases (none vs 6) and ratings volume (27 vs 3). On price, update cadence, ads and monetization model there is nothing between them.

Both are free to download. 洛书 sells 6 one-off in-app purchases. RSSBud asks for nothing beyond the download.

洛书 holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: RSSBud has 27 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 100% of 洛书's written reviews are positive against 50% of RSSBud's.

洛书 ships an update every 4 weeks, RSSBud every 6 weeks. The most recent releases landed on September 23, 2026 and October 10, 2026 respectively.
