The Good: You can access some (not all) of your library. You can read the books fine. Navigation works for most (not all) of your books. You can download books and avoid or minimize using your mobile internet access for that. The bad: Crashes. Buggy. Title searches are exact match only. Text searches only search the content you downloaded. Text searches are any verse with any of the words you typed that it can search for. You cannot search for “and”, “or”, or “not” and several other small words. If you search for “love joy” you get all the references to anything that contains love and joy, so if you only wanted to see items that contained both love and joy, you have to go through all the results to find them yourself. On my device there are only about 70,000 results for that search! The following return the same results: “love joy”, “love and joy”, “love not joy”, etc. (proving that it ignores words like “and”, “not”, etc.). So to summarize - if you want to read your library on the go, WORDsearchBible will probably work for that for most of your books. But if you want to do too much more than that, use your PC or maybe another mobile app that lets you do real searches and facilitates in-depth study on the go.
