# Read A Res vs E本笔记

The clearest difference is in-app purchases: E本笔记 at none against Read A Res's 1. E本笔记 also leads on ads (none vs shown) and iOS requirement (13.0 vs 15.6). Read A Res's advantage is update cadence (every 2 months vs every 13 months). On price and device support there is nothing between them.

Both are free to download. Read A Res sells 1 one-off in-app purchase. E本笔记 asks for nothing beyond the download.

Read A Res ships an update every 2 months, E本笔记 every 13 months. The most recent releases landed on June 4, 2026 and December 2, 2025 respectively.
