# SORARI vs 読書尚友

The clearest difference is rating: SORARI at 4.8 against 読書尚友's 4.0. SORARI also leads on review sentiment (71% vs 50%) and ratings volume (39 vs 1). 読書尚友's advantage is update cadence (every 2 weeks vs every 2 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. SORARI sells 2 one-off in-app purchases and 読書尚友 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

SORARI holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: SORARI has 39 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 71% of SORARI's written reviews are positive against 50% of 読書尚友's.

SORARI ships an update every 2 months, 読書尚友 every 2 weeks. Both last shipped on November 11, 2026.
