# OFD阅读器 vs 理想同学

The clearest difference is review sentiment: 理想同学 at 68% against OFD阅读器's 0%. 理想同学 also leads on in-app purchases (none vs 3). OFD阅读器's advantage is rating (4.8 vs 4.3) and iOS requirement (12.0 vs 15.0). On price, ratings volume, update cadence and ads there is nothing between them.

Both are free to download. OFD阅读器 sells 3 in-app purchases, starting at $3.99 per month. 理想同学 asks for nothing beyond the download.

OFD阅读器 holds the better App Store score, 4.8 against 4.3. Both are backed by a comparable volume of ratings — 8 and 16 respectively. Written reviews complicate that: 0% of OFD阅读器's written reviews are positive against 68% of 理想同学's, so the app with the better star average is not the one people write more warmly about.

OFD阅读器 ships an update fortnightly, 理想同学 every 2 weeks. The most recent releases landed on September 9, 2026 and September 22, 2026 respectively.
