WHAT PEOPLE ARE SAYING
“LOVE this app! so easy to import data from goodreads. it excels where others fail. like letterboxd for books. Really glad there’s finally a good book app out there, i’ve been waiting for something like this!” — scruffythejanitor01
“I love the UI of this app, easy to use and aesthetically pleasing. Also, I've been struggling getting back into reading and the screentime feature has helped me loads. I haven't been able to read this much since 4 years ago. Thank you Margins” — mitakaluvr
“The search by vibes is so cool. I am a WWII buff, but this search popped up a two-book WWII saga I had never even heard of, much less read. It ended up being my top read of 2025.” —Michigancolt
