## KCLS Reviews in United States

### ***-- "Doesn’t always work"
They’ve fixed the last issues I mentioned but issues still remain: the Return book function doesn’t work from the app anymore, which extends wait times. I wish the search bar was coded less narrowly to correct for misspellings or allow for less than exact search terms.
-- Julz734652, 2025-10-22

### ***** "Kids love it!"
Easy to log in and fun books to read!
-- By Amaar, 2025-02-24

### ***** "Excellent!"
Excellent app!
-- Peachy lemon~123, 2025-02-01

### **--- "No notifications"
Why on earth build an app that let’s you place holds on books but doesn’t notify you when they’re ready to be picked up? It’s beyond stupid. “We notify by email” Sorry, no. It makes zero sense to have one half of an interaction occur in one place and the second half in another. No other app does this. Even other apps used by KCLS like Libby and Overdrive don’t work that way.
-- Geisha Pupe, 2024-09-08

### *---- "Bad Update"
This app was great until the recent update on 4/2. Now it takes so long to process information that the app times out. I cannot use any of the “bookshelf” features at all. They show up blank. Please fix this!
-- LFT12345, 2024-04-03

### ****- "Yess"
I think that this app is so helpful for kids adults and really all ages. It is help me get through so many books in such a short time while cleaning cooking and just the lack of social time that I would have to endure just trying to go out and check out a book 10 out of 10 would recommend
-- Hebgsjebebhd, 2024-03-24

### **--- "Lack of notifications"
The app doesn’t provide any notifications for the account, whether it’s library material ready for pick up or due.
-- U_Suck!!, 2024-01-29

### ***-- "KCLS App"
I gave this review because the app is constantly glitching or asking me to sign in to check out a book and it won’t accept the card or passcode. Otherwise the app works fine. It would be nice to get those bugs fixed, but for now, I give it a 3/5.
-- jieikns, 2023-11-22

### **--- "Nice when it works…"
Nice when it works… half the time I try to use this app there seems to be an issue. Lots of prompts to log in followed by system errors. Wish I could access it reliably.
-- xo.coko, 2023-08-13

### **--- "Good app but search has stopped working as of recently"
It's a good app but whenever I go to search a blank white screen shows up.

I can still check my holds and my shelves but the search not working as of now really hinders this app

Once it gets fixed I will be sure to update my review.  I love KCLS and I live checking out bookend I hope this gets fixed.
