I want to like it more, but needs work


I've used this app for a few years, and the concept is wonderful. But there are too many buggy issues for me to like it more. I still occasionally browse for other cataloging apps.
If I click to sort or search, the results don't show up until I click in the main area again. And the top sort/search box doesn't go away easily. I have to scroll up to get it to disappear. And if I scroll up again too far (which often happens), the box reappears when I don't want it to.
I like that it backs up to a CSV or zip file, but I can't see how to rename that file. So all my backup filenames are still dated from 2015.
I like that the app automatically fills in the rest of the book information when I scan an ISBN, but it's not always accurate. It doesn't always get the right edition, even if the ISBN is correct.
I like the "loan" field for each book, so I can keep track. And I can make my own labels, which is nice.

Have your whole library in the palm of your hand


I am a true bookworm. I am one of those people whom actually purchase books that I believe I will enjoy and read more than once. I also enjoy having the whole series when it comes to books. The authors that I enjoy the most I look to obtain all their books. The only problem is that when you get to the point where you have so many books it's easy to end up buying the same book sometimes more than just once. With this app I am able to have my whole library right in the palm of my hand and I can see if I already have the book or if it is one that I am looking for. I also can see what other book lovers have to say about books before I get it. Plus I am not tech savvy at all but this app makes it so easy that I have not ran into a problem yet.

Strictly for light readers


I have been using this app since 2013. My database is not large but it does have right at 2400 books entered. You get no support, and no suggestions, in making it work best for you. It's a long learning curve. I never rated it before because I was always finding new and better ways to organize my data. Now I realize it is simply cheaper just to buy the multiple copies of your books than waste your time with this ultimately useless app. I am about to lose over 4 years of data input, impossible to spend that time again re-entering the data. Back up and restore practically unusable. Repeated emails, and crash reports requesting help or a better understanding of the process go unanswered. Find another developer that knows the seriousness of losing your years of input and investment of time.
