Looking for 10–20 beta testers for my Windows app that syncs audiobooks with EPUBs

Hey everyone, I created an EPUB3 reader/creator that takes separate audiobook and EPUB files and turns them into one synced file, so you can read along while the audiobook plays. Besides the read-along creator, it has a built-in reader, text-to-speech, a transcriber, a file converter, and a library. Nearly everything works offline after the initial setup, and there's no ongoing subscription cost, so that's a plus too. It's currently available on the Microsoft Store (link). I'm looking for 10 to 20 beta testers to try out the app and give me some general feedback, like what you liked and what you didn't, and to let me know if you find any bugs. I'd also like to know your device specs (CPU and GPU) and how long it took you to generate a synced read-along. Lastly, if you can, let me know if you would buy it and what you think it's worth. If you're interested, reply to this post or send me a DM and I'll send you a link with a promo code for a free download (yours to keep). I included some screenshots for anyone who wants to check it out. General Microsoft store link below, if interested in being a beta tester reply or dm me and ill send you the link for the free download apps.microsoft.com/store/detail/9N8S65K6WMND P.S. Don't feel pressured to give all that feedback if you can't. Any bugs you find and general thoughts are very much appreciated.
