Going to the library again
We had stopped going to the library because it was getting too hard to sift through books to find ones that fit our family values. I found this book app on TikTok, and my kids are so excited to be able to go to the library again. They bring me a stack of books they're interested in, and I just use the barcode scanner. We get to leave with a giant backpack of books, and everyone is happy.
Looking for something exactly like this
Our family loves to read and is at the library on a weekly. This resource helps us both to catalog books we have read and provide a helpful resource for others.
I use this all the time now! I'm a house mom at a therapeutic boarding school. We have kids who would be triggered by things other kids might be able to read with no issues. The amount of description this app provides is amazing. I set the profiles to "high school," "middle school," and "elementary school" so I can easily see descriptions for a variety of ages. I was looking for books at Goodwill and this helped me find some great books and avoid others.
We've been using it weekly for the library. Thank you SO MUCH for making this app.
