You could do like Apollo, have $1/$2/$3/$5/$7 tiers for people that want to support you and later add features to the higher tiers as you're going I started the Patreon with just multi-account and now added scheduling

Definitely an option, but I think there is a certain appeal in a dead simple pricing scheme

Indeed, but I received feedback that people just wanted a quick way to support the project, so I just added the lower tiers I would like to have just two too, but people like to have options
