What is Boox? Meet the trendy e-readers that BookTok loves.

Just as BookTok goes through phases with its favorite books, it channels the same attitude toward e-readers .

While Kindles are undoubtedly the e-reader to reign supreme, plenty of competitors come in swinging to dethrone it.

The latest is Boox.

In between users touting their Kobo Clara and Kindle Paperwhite on BookTok, you'll also find a passionate, dedicated group of people discussing their Boox e-reader.

The Palma Pro 2, in particular, has caught the interest of plenty of folks who want an e-reader even smaller than what Kindle can offer.

Having tested several Boox e-readers myself, I was admittedly surprised by the device's popularity because these aren't your regular old e-readers but are instead e-ink tablets.

Unlike Kindles or Kobos, Boox e-readers let you access any app in the Google Play Store, so your books from any app (excluding Apple Books) are all available on one device.

Ever dreamed of being able to update your Storygraph or GoodReads right on your e-reader? Well, you can download those to your Boox, too.

So here's what to know about Boox, the e-readers that BookTok can't get enough of.

Onyx created Boox e-readers as an alternative to traditional smartphones and tablets , which have bright screens that cause eye fatigue and strain.

The e-ink tablets have softer interfaces so you can read for hours at a time without bright, glossy blue light.
