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… -- Capt_Tedders, 2026-10-01 ### ***** "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. :) -- elle0333, 2026-09-22 ### ***-- "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. -- Quickening, 2026-09-06 ### ***** "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! -- Jordimay, 2026-08-29 ### ***** "Love this reading tracker app" This reading tracker app has the best features like a social feed to get recommendations, personal reading tracking, and trees!! The best reading tracker app on the App Store!! -- Sdsd12345sarah, 2026-08-26 ### ***** "LOVE!!" Love this app and the tree theme! I actually want to track my reading while using this app! -- BookMouse123, 2026-08-24 ### ***** "Reading is FUNdamental!" Reading is fundamental and a lifelong activity for me, but I’ve never used an app to track my goals and progress. I enjoy connecting with family and friends on Understory and benefit from the book reviews posted. My virtual forest is growing, and since I upgraded to premium, real trees are being planted as a result of my progress. -- Llreadr, 2026-08-22 ### ***** "So social so fun" I love connecting with other users and chatting about the books we’re reading. I’ve gotten so many good recs because of them -- Rmor97, 2026-08-20 ### ***** "Great social & tracking platform for readers!!" I’ve been using Understory for a hot minute now and I have really enjoyed it! The streak mechanism and tree watering feature definitely makes me more inclined to log my reading every day on Understory rather than other tracking apps. The little monthly missions are also a major plus that make me feel more motivated to not only continue my reading habit, but to branch out to other genres as well! I’ve had so much fun connecting with my friends on this app and keeping up with what they’re reading, which was not an experience I was necessarily having with the Amazon counterpart because of how much other irrelevant content they push onto your social feed, so being able to actually see my friends’ updates on Understory has been a welcome change. -- TaylorGray52, 2026-08-20 ### ***** "Amazing!!" I can’t wait to use this tracker more! It is so aesthetically pleasing and very engaging!! Will be switching over to this -- whscbowyensnac, 2026-08-20 ### ***** "Great for active and occasional readers" This is a wonderful reading tracker that has helped push me to read more. Whether it is reading a few pages each day to keep my streak alive or finding new books recommended by others that I would not have previously considered, this app has been the reason I have read more this year than I would have. It is very easy to use and I recommend it whether you read a book a month or a book a week. -- FlyEaglesFly-4133, 2026-08-19 ### ***** "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. -- Books#1!, 2026-08-19 ### ***** "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. -- Iluv2read4evr, 2026-08-19 ### ***** "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 :) -- jordy_r, 2026-08-19 ### ***** "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. -- jgrant63, 2026-05-20 ### ***** "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. -- ibpeepo, 2026-05-19 ### ***** "Love this app!" Understory is such a great reading tracker! It’s easy to use, help me stay engaged with my friends and what they’re reading, and it makes it fun to complete my reading goals! -- cassieb57, 2026-05-18 ### ***** "Keeps me reading!!" I love the streak feature. It will motivate me to read (at least a few pages) on days when I otherwise wouldn’t have. The interface also just feels fresher and easier to navigate than a typical book tracking app. And I get to grow little trees!!! Love it 💚🌳🌴🌲🌱 -- oliviaharvey, 2026-05-18 ### ***** "Truly the best reading log app" I’ve tried every single app to log reading. This one is not only far prettier and more functional, but the community it offers is truly special. Not only that, but it is also run by indie designers who are passionate about books! Truly using this app is one of the best parts of my day, and using it is a one of a kind experience. -- autogen158, 2026-05-18 ### ***** "My new favorite reading tracking app!" This app has really helped me read more but in a way that doesn’t feel like a chore! I’ve tried quite a few reading trackers to try to get away from Goodreads and none of them clicked for me until Understory! I especially love how you can grow real world trees as a premium user so it’s awesome that my reading can support an indie team and have a positive environmental impact! The UI is so cute, especially with the plant theme, and I love growing my trees as I read. I’m competitive so I also love the leaderboards but I know I’m competing in the middle, not at the top, and it’s been a fun additional feature and doesn’t take away from reading for fun! Would highly recommend whether your reading goal is 1 or 100! -- Booklover1450, 2026-05-17 [View all Understory reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Understory In-App Purchases | Item | Price | |------|-------| | Understory Premium - Monthly | $4.99 | | Understory Premium - Yearly | $49.99 | ## Understory Store Rankings | Chart | Country | Category | Rank | |-------|---------|----------|------| | Top Free | Austria | Books | #64 | | Top Free | Philippines | Books | #102 | | Top Free | Malaysia | Books | #119 | | Top Free | Portugal | Books | #126 | | Top Free | Ireland | Books | #134 | | Top Free | Greece | Books | #149 | | Top Free | Hungary | Books | #150 | | Top Free | Czechia | Books | #178 | | Top Free | United States | Books | #191 | | Top Free | Netherlands | Books | #192 | | Top Free | Sweden | Books | #211 | | Top Free | Mexico | Books | #212 | | Top Free | Norway | Books | #231 | | Top Free | Romania | Books | #238 | | Top Free | Colombia | Books | #246 | ## Understory Available In - [United States](https://apptail.io/app/understory-reading-tracker-mrKz/united-states) - [Hungary](https://apptail.io/app/understory-reading-tracker-mrKz/hungary) - [Philippines](https://apptail.io/app/understory-reading-tracker-mrKz/philippines) - [Romania](https://apptail.io/app/understory-reading-tracker-mrKz/romania) - [United Kingdom](https://apptail.io/app/understory-reading-tracker-mrKz/united-kingdom) - [Canada](https://apptail.io/app/understory-reading-tracker-mrKz/canada) - [Belgium](https://apptail.io/app/understory-reading-tracker-mrKz/belgium) - [France](https://apptail.io/app/understory-reading-tracker-mrKz/france) - [Qatar](https://apptail.io/app/understory-reading-tracker-mrKz/qatar) - [Estonia](https://apptail.io/app/understory-reading-tracker-mrKz/estonia) - [Egypt](https://apptail.io/app/understory-reading-tracker-mrKz/egypt) - [Finland](https://apptail.io/app/understory-reading-tracker-mrKz/finland) - [Ghana](https://apptail.io/app/understory-reading-tracker-mrKz/ghana) - [Indonesia](https://apptail.io/app/understory-reading-tracker-mrKz/indonesia) - [Ireland](https://apptail.io/app/understory-reading-tracker-mrKz/ireland) - [India](https://apptail.io/app/understory-reading-tracker-mrKz/india) - [Italy](https://apptail.io/app/understory-reading-tracker-mrKz/italy) - [Jamaica](https://apptail.io/app/understory-reading-tracker-mrKz/jamaica) - [Jordan](https://apptail.io/app/understory-reading-tracker-mrKz/jordan) - [Cayman Islands](https://apptail.io/app/understory-reading-tracker-mrKz/cayman-islands) - [Luxembourg](https://apptail.io/app/understory-reading-tracker-mrKz/luxembourg) - [Latvia](https://apptail.io/app/understory-reading-tracker-mrKz/latvia) - [North Macedonia](https://apptail.io/app/understory-reading-tracker-mrKz/north-macedonia) - [Macao SAR China](https://apptail.io/app/understory-reading-tracker-mrKz/macau) - [Mexico](https://apptail.io/app/understory-reading-tracker-mrKz/mexico) - [Malaysia](https://apptail.io/app/understory-reading-tracker-mrKz/malaysia) - [Nicaragua](https://apptail.io/app/understory-reading-tracker-mrKz/nicaragua) - [Panama](https://apptail.io/app/understory-reading-tracker-mrKz/panama) - [Peru](https://apptail.io/app/understory-reading-tracker-mrKz/peru) - [Portugal](https://apptail.io/app/understory-reading-tracker-mrKz/portugal) - [Singapore](https://apptail.io/app/understory-reading-tracker-mrKz/singapore) - [Ukraine](https://apptail.io/app/understory-reading-tracker-mrKz/ukraine) - [Uruguay](https://apptail.io/app/understory-reading-tracker-mrKz/uruguay) - [United Arab Emirates](https://apptail.io/app/understory-reading-tracker-mrKz/united-arab-emirates) - [Vietnam](https://apptail.io/app/understory-reading-tracker-mrKz/vietnam) - [Armenia](https://apptail.io/app/understory-reading-tracker-mrKz/armenia) - [Australia](https://apptail.io/app/understory-reading-tracker-mrKz/australia) - [Bulgaria](https://apptail.io/app/understory-reading-tracker-mrKz/bulgaria) - [Brunei](https://apptail.io/app/understory-reading-tracker-mrKz/brunei) - [Cyprus](https://apptail.io/app/understory-reading-tracker-mrKz/cyprus) - [Czechia](https://apptail.io/app/understory-reading-tracker-mrKz/czechia) - [Germany](https://apptail.io/app/understory-reading-tracker-mrKz/germany) - [Dominican Republic](https://apptail.io/app/understory-reading-tracker-mrKz/dominican-republic) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
