Help building on nostr.

I am building an app intended to be a community and marketplace of best practice - an "operating manual for your day, owner's manual for your life". I coach people who are struggling with being lost in life, and do so through the power of instilling daily routines with purpose.

It basically combines a journal, scheduler, workout tracker, and a few other things. Effectively templates for rituals for morning, shutdown, deep work, & anything else the user wants to do.

We are wanting to use lightning to make payments - for ex, I could post my mother's barbeque meatball recipe, and for a few cents you can add it to your library and fork it however you like.

I've been interested in nostr since I first saw it, and want to know if I can run this on nostr - and how. My developer is even less educated about nostr than I, but giving users absolute ownership over their data and ensuring privacy is default and publicity is a choice is very important to me.

I would like to talk to someone about building on nostr that could point us in the right direction. we are currently beta in ios and will build for android and web as well.

Thank you!
