DAISY book converter, any interest?

hi all, I had a bunch of DAISY format books that I wanted to convert to m4B files for use with Apple Books and other standard audiobook players. I couldn't find anything that would do it with automatic metadata lookup, cover art download and the ability to skip intro and title pages, so I've written a little app for MacOS and iOs. It facilitates converting all DAISY book formats to M4V, single MP3 files with chapters or split MP3 / M4A / AAC / AIFF files. Automatic metadata lookup and extraction from the DAISY files, cover art support, even basic audio trimming and chapter editing support. Is there any interest in this? I may drop a beta if it is and then release it in the app store. It's particularly useful for those in the UK who use the RNIB reading services. Let me know.
