## Book.io Reviews in United States

### ****- "Much improved from V1!"
Love the addition of dark mode! It feels SO MUCH FASTER than the original version of the app. The books load quickly and I don’t get the reloading screen like I used to. Definitely still looking for more features…would love to be able to press and hold on a word to bring up the little contextual menu where I can select “Look up”, as is standard through most of the OS. Would love to be able to use that to see definitions without having to leave the app. App feels great, much improved, looking forward to many more features to come!

### ***** "The future of books"
Book.io harnesses the innovative power of blockchain technology to redefine the experience of book ownership in the digital age. This cutting-edge app empowers readers with true ownership of their purchased content, free from the constraints of traditional centralized platforms. It echoes the tangibility of owning a physical book, yet with the added flexibility and modernity of the digital world. Not only does it allow you to immerse yourself in a diverse library, but it also offers the unique opportunity to resell your digital books. This feature not only fosters a sustainable reading culture but also adds a dynamic aspect to your digital library, much like a traditional bookshelf.

### ***** "What a game changer"
Fantastic release by the Book.io team here. So much happening at such a fast pace. They are changing the ebook landscape and I'm excited to be here for the ride.

Hoping for multiwallet support next.
-- J. Stumpp, 2024-01-16

### ***** "Amazing!"
Book.io is a game-changer.
-- I am chubby, 2024-01-16

### ***** "A New Era for Reading 📖"
An application like this is revolutionary for the reading world. The ability to actually OWN your books on the internet with the option to sell & trade them with others is one of those things you didn’t know you needed till you try it.
-- adacat97, 2023-11-04

### ***** "Nft"
Amazing. Project. Nice very simple app to use.
-- bgty23, 2023-11-03

### *---- "Scam?"
Encouraging the use of hot wallets in the crypto space because the devs are too lazy to do security first is a red flag.

If you have a hardware cold wallet, you will be required to compromise your security to participate.
-- myd0j0, 2023-09-03

### ***** "Absolutely love this app....."
Can't wait til we start getting $Book for reading. Trying to collect mark Cuban books while I can. Not a completist so I don't care if I get them all but it would be nice
-- Aerokossa, 2023-07-21

### ***** "Cardano is the best"
Honestly the best app to own and read digital books. I love how easy it is to purchase a book and how intuitive the reading app is. I love the fact that I can gift the book or re-sell it if needed afterwards. Thank you for making this possible for everyday consumers like my-self. The power of NFTs truly shines here.
-- Kal Rakov, 2023-06-30

### ***** "I can actually own my e-books"
Having the ability to actually own my e-books is a game changer.  Instead of just renting a license to read a book I can actually own it.  I can lend it out to friends and family,  I can sell it,  or I can hold it forever.
