My reading orchard

Understory has completely changed the way I track my reading. I love the unique tree-growing aspect of the app—watching my reading grow into a little forest makes tracking each book feel much more rewarding. It gives me a visual way to see my reading progress and makes it really satisfying to look back at everything I’ve read.

It’s simple, beautiful, and genuinely makes me want to read more. If you love tracking your books, Understory is definitely worth trying.

Cleanest Reading Tracker

Understory is my favorite reading tracker that I have used. I joined a reading group with a few friends, and it’s fun to see their reading streaks and book reviews right in the app. It also has audiobook tracking functionality. The interface is easy to use and has a clean design with lots of great features like wishlists and reading lists. I would recommend it for individuals or groups like book clubs or classrooms.

My new favorite way to track my reading!

This app is so good at motivating me to read every day. It sends reminders and rewards daily reading with the cutest concept for watering your garden! The design is beautiful and makes it so much fun to track my reading compared to other apps that feel more like a chore. I also love seeing what my friends are reading and interacting with their reviews. It has helped me find so many new books that I probably never would have found on my own! If you’re trying to form a healthy reading habit this is the best app to help you with that :)

Excellent Book Tracker

This is a great app for keeping track of reading. I value that the design is clean/doesn’t feel cluttered, and that it does exactly what it says (helps you track books) and doesn’t bombard with any other ads or gimmicks. Just nature themes and books.

Maybe the best reading tracker

This might be the nicest looking reading tracker out of them all. It's got all the features of any other book tracker so you're not giving anything up, and it just plain looks better. Love the shareable cards, love the tree planting. Imported my books quick and easy. Reached out to the developers to ask a question and they got back to me so fast! So far, amazing experience, will probably switch long term.
