Verdict
The clearest difference is rating: PureLibro at 4.6 against 読書尚友's 4.0. PureLibro also leads on ads (none vs shown) and review sentiment (77% vs 50%). On price, update cadence, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. PureLibro sells 6 in-app purchases, starting at $0.99 per month and 読書尚友 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
PureLibro holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: PureLibro has 365 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 77% of PureLibro's written reviews are positive against 50% of 読書尚友's.
PureLibro ships an update every 10 days, 読書尚友 every 2 weeks. Both last shipped on November 11, 2026.
