# UNI2K vs 已阅

The clearest difference is in-app purchases: UNI2K at none against 已阅's 10. UNI2K also leads on iOS requirement (12.0 vs 15.6). 已阅's advantage is update cadence (fortnightly vs every 6 weeks). On price, ads and device support there is nothing between them.

Both are free to download. 已阅 sells 9 in-app purchases, starting at $0.99 per month. UNI2K asks for nothing beyond the download.

UNI2K ships an update every 6 weeks, 已阅 fortnightly. The most recent releases landed on May 18, 2026 and September 18, 2026 respectively.
