# 优读 vs Kilonotes

The clearest difference is ads: 优读 at none against Kilonotes's shown. 优读 also leads on rating (5.0 vs 4.6) and iOS requirement (10.0 vs 15.6). Kilonotes's advantage is ratings volume (4.9K vs 1). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. 优读 sells 2 in-app purchases, starting at $1.49 per month and Kilonotes sells 20 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

优读 holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Kilonotes has 4.9K ratings behind it against 1, so its average is the more settled of the two.

Both ship on a similar rhythm, roughly every 2 weeks. The most recent releases landed on June 25, 2026 and September 27, 2026 respectively.
