Mobile Apps as NFTs?

As you all may or may not know I've been working on my own social media meta-client for a while now and will be doing an alpha release for SailfishOS any day now.
Android will follow later.

I will put it on the Google Play Store at some point but I was wondering what my alternatives would be if the app were not to be accepted. (I want to make money on this.)

Has selling a mobile app as an NFT ever been done before? Through what store or channel? How are updates handled?

(I am familiar with Nostr's Zapstore and Atari's game-as-NFT.)
