Can we just make normal apps and then just use nostr to give a “free” social media feature? Also payments incorporated then through lightning ?

Cool gym app where you can connect with friends for progress and motivation but buy programs, merch, 1:1 sessions or whatever with lightning. Cool that we can leverage it to pay “people” through their Nostr profile
