LibraryThing

Whenever I try to open the author tab, the app crashes. Not a fan.

Will ask you to create an account then won’t let you log in.

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.

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!

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.

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, a

Edit button hangs up on iPhone.

“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”

Thank you for updating the issues! This is a great app for reviewing and adding to my collection. Really handy in bookstores.

I have loved this app and I use it for my very large home library. But it has recently becoming very slow and often crashes when I am entering books. Would love to see it fixed!

The app won’t allow me to edit books. As soon as I hit edit it goes to a white screen that just spins and then it would let me close it.

The website is wonderful, but the app often crashes or freezes on both my phone and tablet, and the barcode scanner consistently causes the app to stop working. It would be much more useful as an app if the barcode worked and were not so slow. (Edit 6 December 2025) The app can still be slow some days, but it doesn’t crash nearly as often and the barcode scanner works again, so I am very happy with it! I also appreciate that it’s functional without fluff or ads. I respect the developers for that.

Not user friendly

For the most part, I really like the app; however, it is missing a key source Barnes & Noble. I would also like to see Target added because both of these retailers offer exclusive editions. The ISBNs on these books are different, so when you scan or enter the number, nothing comes up. I do like the ability to scan my books, which has made cataloging my library pretty easy. I just wish that the app had more features of the website. I log all the books in the house, but I like to categorize them by location, and if it’s my book or my kids’. I have to create categories on my computer, then I can

Please add a category for reference materials. I don’t exactly “read” a dictionary but it isn’t a favorite either. I was not able to add books from Japan even if they had English titles and an ISBN.

Except for scanning books, the website is better

I’ve been adding books, and I have about 2271 added, then noticed the number doesn’t go up as I add. It does sometimes, but not always. Am I losing titles somewhere..or it’s not adding correctly? Love the app except for that

I like the simplicity of this app. However, it needs options to import data from other apps like Kindle, Barnes & Noble, Goodreads, etc. Also need to be able to customize shelves.

The barcode scanner is great. I love how fast I can add books. However. I have books in my collection without an ISBN (ex. the volume 0 series from BOTM) that I cannot add. An option for users to manually add books to the catalog that aren't in the database would be amazing.

This doesn’t allow you to change the names of the files, you have to group them all in one place or remember which file you put them in

Love this app for organizing my daughter’s hundreds of books. Sadly, tags and custom book entries aren’t working. If they did, it would be perfect!

This app worked great while I was scanning my books but as soon as I started to scan my movies and cds it stopped respecting my selected sources. No matter what I have chosen it always uses Bowker Books in Print, which results in most details being excluded like the movie cover and dates. This means either a different scanner has to be used or manual entry which means not using this app at all. Please fix this.

Excited to start using the app to keep track of my books. However, it lacks basic functions and frequently doesn’t save the edits I try to make. The save option is no where to be found after I key in the changes. This is happening with increasing frequency.

Downloaded this app today to start cataloging my home library. After scanning 30 books it brought up a screen that said I needed to pay $29.99 to upload more books. I loved a lot of the features that this app has but I just don’t think it’s worth it to pay $30 when there are plenty of apps that do the same thing. I might consider paying $10 but not $30. Deleting this app!! Lower the price & I’ll consider using it again.

Crashes often. No back button to get from scan mode to the home page. Frustrating.

Started off great. Now it never works.

I had high hopes for this app. However, it has a lot of flaws, and programming that does not address basic user needs. It’s basically useless for anything that isn’t currently in print. So if you are book collector, expect to have to do a lot of manual searching and sorting through possible correct records, but no guarantee it’s the right edition or printing. There’s a lot of available free online records out there to use, but this does not have many items that collectors actually would like to see. You might get incorrect entries, requiring you to enter in the correct information, there’s goi

Great idea and amazing to have a catalog, unfortunately the app glitches when I try to go into the tags tab. Tags were the main reason behind the catalog for downloading this app for me, hence the 4 stars.

It’s free! This is my favorite app for keeping track of my inventory of books
