Palace is a free, easy-to-use e-reader app that lets you find, check out, and read or listen to books from your local library. It’s been said that libraries are “palaces for the people” and the Palace app gives you instant access to your local “palace” any time, right from the palm of your hand. All you need to sign up is your library card! And even if your library isn’t using Palace yet, you can still read more than 10,000 books--from children’s books to classics to foreign language books--for free from our Palace Bookshelf. The Palace app is built and maintained by Lyrasis, a not-for-profit organization working in partnership with Digital Public Library of America with funding from the John S. and James L. Knight Foundation. For more, visit https://thepalaceproject.org.

Verdict

The call

The clearest difference is rating: The Palace Project at 4.6 against KMK Optometry Pages's 1.8.

ReceptionRating · Positive reviews · Number of ratings

The Palace Project holds the better App Store score, 4.6 against 1.8. That said, the two scores are not equally well evidenced: The Palace Project has 5.5K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 27% of The Palace Project's written reviews are positive against 33% of KMK Optometry Pages's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

The Palace Project ships an update fortnightly, KMK Optometry Pages every 2 months. Both last shipped on October 24, 2026.
