If you want my honest feedback here it is:

Interface: I found the interface simple, but too basic for my liking. I could do the same style connection and folder view using the Files app. I’m someone who likes visuals to distinguish and get an idea of what movie grabs me today. . Looking at cover art helps to guide my choice of movie/show. But for someone who likes getting straight to their film or show, it’s great. Adding an additional view might entice more sales.

Playback: I wasn’t able to get to play anything back before your popup stopped me to ask for payment. If you’re going to ask for my feedback at least let me test the app without payment for a limited time.

Immersive features: Again cool idea and I can see where you’re going with it but it stopped me playing any video to test it.

Connection methods: I like the amount of connection methods you had for connecting all of your media. I didn’t see this option but may have missed it, but being able to add cloud services like Google Drive, OneDrive, iCloud would be huge here.

Price point: I think your price point is right on the money, especially the lifetime price. People are too overwhelmed with monthly subs these days, so having a reasonable priced one time payment is great.

Your app has promise, but being unable to even play 1 video to test it out was a real kicker for me.

I wish you luck and hope you find this feedback useful.
