Love the app…but crashing :(
I love this app and it makes it wonderfully easy to scan in books and see the genres and such to categorize them easily. The only thing I dislike is when I’m scrolling through my author section to look for a specific book from a specific author it will crash every time I reach the Rs. Otherwise it’s wonderful, I just hate that I can’t see any of my authors past Q. :(

Best Cataloguing
I’ve been an LT user on desktop for a few years and it’s my favorite cataloging system. Very community based, good newsletters, fun holiday treasure hunt events with riddles.
On mobile you can catalogue your books with all the data points you need to feed the sweet metrics/charts offered. It’s so fun.
I’m excited for the App update, LibraryThing admins and users are truly incredible

Edit book feature broken on iOS 27
On iOS 27, the “edit book” button opens a blank page that hangs forever and never loads, so one can no longer edit book entries through the app. This drastically reduces the functionality of the app.
So many possibilities that aren’t there
The app is nowhere as good as the website. The thing I need the most is a simple search option, for books I don’t own. I just want to check books publication dates or cover variations, but I can’t search for anything on Google with it being completely ruined by AI, and LibraryThing has always been my goto online. The app however, is just so frustrating bc you can only look at your own collection.

Easy to use, when it runs
The app is great for scanning a cataloging books, but is too unstable to use for looking up later. It reliably crashes when scrolling the list.
Good but it’s been crashing none stop recently
I haven’t had any issues until recently, and not it seems like i can’t add anything out even look up stuff via the app. What am i doing wrong?

The app is broken
Scanning doesn’t work. After newly creating an account and installing the app for the first time, most of my books just says “The data couldn’t be read because it isn’t in the correct format” despite collecting the correct ISBN from the scan. Of course the same ISBNs work on the website without issue.
Additionally many buttons cause the app to crash. Reinstalling did not help.

AMAZING!
My mum suggested this app to me when I said I wanted to count all of my books. She has had it for a while (and has about 400 or more books counted) and finds it super useful and amazing. I couldn’t agree more! This app is free, useful and SO fun and easy to use! DOWNLOAD LIBRARY THING TODAY YOU WILL NOT REGRET IT!!! 😀😀😀

Keeps crashing
Whenever I try to open the author tab, the app crashes. Not a fan.
The Worst!
Will ask you to create an account then won’t let you log in.
Non-functional scan
Unable to use the scan feature to add books to my library. The button does not trigger any action. It would be nice to be able to scan a cover and have the title and author returned.
Long Time User
I have used Library Thing for many years. It has made my life so much easier! As a serious bibliophile, I appreciate its ease of use without a lot of unnecessary distractions. It has allowed me to manage our family library of almost 10,000 volumes quickly and efficiently and I cannot imagine life without it! Thank you!

Many features lacking
1) ability to share owns catalogue with friends 2) browsing other peoples catalogues 3) find similar books eg. By the same authors, genre, year, country of origin etc. 4) The app crashes when trying to browse an author’s profile. Still my default cataloguing app but would migrate to another, more modern/advanced if I knew how to.

Badly needs an update
This app hasn’t been updated in over 2 years. It now has glitches which render it unusable for anything other than viewing your catalog, which has at times been buggy on the app to begin with, sometimes failing to find a book that is in my catalog. You can no longer edit books, as other reviewers have noted. This may have coincided with the release of iOS 26. Scanning books into your catalog has been the main benefit of this app through the years. But the app isn’t even very useful as a scanner anymore since you need to use a browser if you want to make any edits.

Infuriating
If you just want to scan barcodes and accept whatever you get, this app will satisfy you. The scanner is as good as you will find.
But if you edit your book entries, this app is treacherous and may as well have been designed to infuriate users who curate their book catalog.
Best practice among app developers is to save edits unless the user cancels them. This app confuses you into thinking it works that way, because the “Save” button disappears when you scroll down, but “Close” is visible at all times in the top bar. So you work your way down the page, adding tags, assigning a bookshelf, adding details, maybe writing a review. Your only visible option for exiting the page is “Close” so you tap it. Guess what? All your changes were discarded!
I have fallen for this so many times, unable to believe that LibraryThing could be so perverse as to require users to select a “Save” button that is concealed most of the time. It’s clear that user testing was neglected. Whoever was hired to code this obnoxious kludge seems to expect app users to think like punch-card programmers. (“If no SAVE command, erase buffer.”)
I wrote this review to remind myself to never again trust this app for any task other than scanning barcodes. Editing the resulting entry must be done in the web browser. As of Feb. 2026 the last app update was 2 years ago. So I don’t have much hope for improvement.

Manca la wishlist
Molto ben fatta ma manca la whishlist!
Frustrating
Edit button hangs up on iPhone.
Can’t add anything
“Add to catalog” does nothing- it presents me no search bar or barcode scanner. It’s just essentially a blank screen that says “nothing recently added”
Love it!
Thank you for updating the issues! This is a great app for reviewing and adding to my collection. Really handy in bookstores.
