# BookFusion vs Mythos

The clearest difference is rating: BookFusion at 4.7 against Mythos's 4.2. BookFusion also leads on ratings volume (505 vs 6). Mythos's advantage is review sentiment (86% vs 77%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. BookFusion sells 6 in-app purchases, starting at $1.99 per month 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.

BookFusion holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: BookFusion has 505 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 77% of BookFusion'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.

BookFusion ships an update every 10 days, Mythos every 2 weeks. The most recent releases landed on September 24, 2026 and September 21, 2026 respectively.
