Output file outdated and unsupported

I like this app. Its easy to use. Unfortunately, I could only record audio on one page. Also, the output file format ebk, is outdated and unsupported by all ebook readers. Unfortunately, I have now spent $8 trying to find an app that will convert this file into a usable format. I think Im going to need to buy a new ebook creator app and start from scratch.
