So far, so good.

I’ve only been using this app for less than a week now. I wanted a simple app to track what I read in a year without all the extra stats you’d get from something like GoodReads and this is exactly what I was looking for. I was able to add my first book read just fine; however, when I try to add a second one to my shelf and search the database, no results come up. Even if I search for the book that is already on my shelf that I was able to find previously, it is no longer there in the search results. I figure this may just be a bug that will need to be squashed since this is such a new app. But all in all, once I can add more books, it’s a wonderful, simple book tracking app.

Bookshelf To Go!

CosyCase reminds me of my reading wishlist 24/7! No more scattered notes of want-to-read books. Sharing my list with friends generates ideas for future books to read. The bookshelves and wallpaper customizes my own personal CosyCorner.
