# Yomu EBook Reader vs Mythos

The clearest difference is rating: Yomu EBook Reader at 4.8 against Mythos's 4.2. Yomu EBook Reader also leads on ratings volume (1.6K vs 6). Mythos's advantage is update cadence (every 2 weeks vs monthly) and iOS requirement (15.1 vs 17.0). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Yomu EBook Reader sells 2 one-off in-app purchases and Mythos sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Yomu EBook Reader holds the better App Store score, 4.8 against 4.2. That said, the two scores are not equally well evidenced: Yomu EBook Reader has 1.6K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 80% of Yomu EBook Reader's written reviews are positive against 86% of Mythos's, so the app with the better star average is not the one people write more warmly about.

Yomu EBook Reader ships an update monthly, Mythos every 2 weeks. The most recent releases landed on September 25, 2026 and September 21, 2026 respectively.
