# KanjiBox vs Satori Reader

The clearest difference is price: Satori Reader at Free against KanjiBox's $4.99. Satori Reader also leads on rating (4.8 vs 4.6). KanjiBox's advantage is update cadence (weekly vs every 3 months). On review sentiment, ratings volume, ads and in-app purchases there is nothing between them.

Satori Reader is free to download; KanjiBox costs $4.99 up front. KanjiBox sells 8 one-off in-app purchases and Satori Reader sells 3 in-app purchases, starting at $8.99 per month. Whichever you choose, the download price is not the number that matters.

Satori Reader holds the better App Store score, 4.8 against 4.6. Both are backed by a comparable volume of ratings — 138 and 218 respectively. Written reviews complicate that: 93% of KanjiBox's written reviews are positive against 90% of Satori Reader's, so the app with the better star average is not the one people write more warmly about.

KanjiBox ships an update weekly, Satori Reader every 3 months. The most recent releases landed on October 20, 2026 and October 18, 2026 respectively.
