### 4/5 — Okay, but

*2025-01-17, version 3.1.3*

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.

### 3/5 — Needs Notifications

*2024-10-10, version 2.8.0*

This is a very clean UI that does the things it is supposed to. The only thing missing is notifications. PLEASE PLEASE PLEASE add due date reminders and holds notifications!

### 5/5 — A gem

*2024-08-28, version 2.8.0*

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

### 4/5 — Great, with one major flaw

*2023-07-27, version 2.6.1*

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!

### 4/5 — Handy!!!!

*2022-09-14*

Thank you for this! It’s super handy ❤️

### 4/5 — Basic, useful, even kinda cute

*2021-09-01, version 2.3.0*

This app is so handy and I love the e-library card feature. Search works well. My only request is that Lists could be added like you can have on the web based account platform.

### 5/5 — Its great

*2021-06-17, version 2.3.0*

It is a great app

### 4/5 — Love the APP

*2021-04-14, version 2.2.1*

Great APP! I work in a library and encourage patrons to use it. I wish you could name the different users and not have to know library card numbers to tell uses apart.

### 3/5 — A good start

*2020-12-01, version 2.2.0*

The app has a cleaner screen and faster response than the website. Allowing account names instead of numbers would make it more user friendly, as would the ability to save default search settings (e.g., author, books only, etc). A defect that makes it impractical for regular use is the lack sorting choices for search results. I’ll stick with the website for now.

### 4/5 — Solid app

*2020-09-04, version 2.1.0*

The app is solid. Works well. Main suggestion is the ability to add a name to the different accounts. I can’t remember which library card number belongs to who. Thanks!
