Instafreebie app


This app helps me keep track of the books I have collected. Give me a chance to have access to the books I accidentally deleted.

Frees up space both on my phone hard drive and tablet and or computer hard drive.

Wish alphabetizing books by authors last name, first name, middle name was an option. Also wish this app were available in Microsoft store for surface tablets and laptops with windows 10 operating system. Or a link that would allow me to download this app on to other devices.

Thank you for the feedback! So glad it is working for you.

Book Delete button?


This is a great app for book lovers. The only problem with it is there is no way to remove books once you have them on the app. You can archive them but never permanently remove them. This means that eventually I shall end up with thousands of read book. As I never read a book twice, I would love the choice of archiving or deleting a book. The customer service is fast, friendly and helpful. The app automatically links so no need to click to remember to add the book.

Needs improvement

Mama cuckoo

I love having my books all in one spot with easy access. However it would be great if we could access the book offers from the app and not have to go to other websites. Plus it would be great to select a genre so you don’t spend a bunch of time looking at books that you have no interest in. Away to set up a profile would be excellent.

I do love the library aspect.
