No on order filter?

The latest update removed the just ordered or items on order that we can previously filter for and place holds on. The old format was way better, much simple and easy to use.

Moving in the right direction

Update: Finally KCLS is moving in the right direction with their app. Certainly much slower than other library systems, but better late I guess. The app is much more robust with features previously lacking and although not the best and most intuitive layout, with trial and error you can figure it all out.

There is still no way to search for books by the same author when on a books page however. And I wish the filter had more options, like filter by genre or subject. I would like to be able to see the reviews & comments in the app and the ability to limit search to a specific word and exclude derivatives of that word.

Overall a much better app than before. But still some room for significant improvements.


Compared to other library app, this one is underwhelming. If you find a book and want to see other books by the same author, you have to back out and search by that author rather than have hyperlinks from the book page. There’s also no predictive text feature, limiting when searching book titles.

It’s glitchy as well. Every time I try to look at my For Later Shelf, it crashes. Just easier to go to the online site and delete the app.

Perfect for easy access to my KCLS account

I am lying in bed using my phone to write this review after downloading the app to do some checking on my holds and renew a book. I am too lazy to do this on my computer now and thought I’d check to see if KCLS has an app so I can check on things without my computer. So happy to see they do! Even happier it works perfectly!!

Renewing books and checking holds couldn’t be easier. Logging in is as simple as on the computer. The user interface is pleasing to the eye and easy to navigate. Searching for books is easy if you know you are looking for.
