So easy and fun

Got my friends and family to join and it’s so fun. Better than Goodreads in my opinion. Hopefully it can be translated into Spanish soon so I can invite more of my family!

Motivational

Well Kathy, you are a genius. Fantastic way to track your current reads, organize future novels, and motivates you to keep it up. Fantastic interface for interacting with other readers. And, you grow real trees just by reading…

New Book Log

I just downloaded this app after seeing it on TikTok advertised as an app to review and record your reading progress to grow trees! No AI supposedly used and the art style is very cute and easy to navigate and join reading groups to find others with a similar reading tastes! Plus, if you have the premium, every 3 books finished = 1 tree planted! Great concept, hopefully the attraction of the app is able to be maintained. :)

Not the best

The idea behind it is cute, but it’s too basic. I’m not at all impressed with the Goodreads import function. It completely screwed up my finished book count, which is noticeably inaccurate and missing numerous books, not to mention books in my DNF and my want to read listings. Also, to actually plant real trees, you have to pay for a subscription. But the app is too basic to make it worth paying for. Even the free version of Fable has more and better features than this one. Perhaps with more updates, it will become something worth spending money on, but right now it isn’t. There are better tracking apps than this out there.

Response from developer

Thanks for your thoughtful feedback! We'd love to hear more specifics about inaccuracies with your import. If you're interested in sharing more, please drop us an email at support@understory-app.com. Most users are very pleased with their imports, but it's not a science, so we'd like to see what went wrong with yours so we can improve. And yes, planting real-world trees is a Premium feature, but planting virtual trees in your Understory forest is free to all users! Happy Reading, The Understory Team

So Much Fun

This is such a fun concept and a great way to track your reading. I also love the community element and how the app encourages you to engage with other readers. Looking forward to more people discovering this app over time!
