1. 4/5Great, with one major flaw

   The app makes it way easier to check my library info than using the website. I like that I can also save multiple library card numbers so I can easily switch between my account and my kids’ accounts and manage all our books, due dates, and holds. The one major oversight is that I can’t find a way to remove an old library card number. We all recently got new library cards and after updating the card numbers for the login, I have both the new and old accounts showing. I can’t remove the old cards and it didn’t just replace the old card numbers with the new ones so now my list of logins shows all the old and new card numbers. Even after deleting the app (which also supposedly deletes all saved data too…) and reinstalling the app, all the saved card numbers, including the old ones, are still showing up. PLEASE make a way to DELETE an outdated library card number!

2. 5/5A gem

   This little app is everything it should be and nothing more. A rare find these days.

3. 4/5Okay, but

   It’s helpful to be able to see at a glance which books I’ve taken out from which libraries and see how long my loan extends until. It’s also really helpful to have every library’s address, phone number, and hours listed. But, I strongly wish there was a feature where I could “favorite” certain libraries (from my neighboring towns) and then when I go to look up books, be able to see if the book is available at those favorited libraries without having to make individual searches for the same book over and over again for every single library in my area. When I’m on my local library’s website, there is an online catalog that tells me “this book is not currently available at our library, BUT, the book is available at *these other* libraries,” then it lists out every CW Mars library and whether or not the book is available at each location. I wish this app had that feature in general, but more specifically that it had that feature and that we had the ability to narrow the long list of CW Mars libraries down to just a few chosen favorited libraries. It would streamline finding where I can take out my chosen books! As this app is currently, the only use for me personally is to see which books I’ve taken out, but it would be infinitely more helpful to me if it allowed me to see at a glance, from a single search, which libraries in my area currently have available the book I’m looking for.

4. 3/5Handy, but could improve a little

   This is a bit handier than accessing through the browser, but it would be more useful if we could switch between several accounts without having to log out and back back log in. As a parent managing my own account and my children’s, I have resorted to memorizing their library card numbers. It would be ever so much more convenient to be able to switch seamlessly by simply selecting the account.

5. 3/5Great potential

   I think this app has a lot of potential although it is limited in some ways. Some features are only accessible to larger libraries? I only have limited features. I wish I could see the calendar of the larger libraries in my area and not just the tiny library where I got my library card. All I can do is search the catalog, see my account, and place holds.
