The UI here can be tricky for mobile, but somebody can do a micro app to set the "algorithm" you want up and save it as a Nostr event (new NIP). Clients would just download and run with it.

It might be cool to add it to the existing public profile nip. It would be interesting to see which algos people use. You could effectively vote for your favorite algo just by using it and devs could get feed back more easily.
