ROMIO

ROMIO is an all-in-one social workspace platform — it combines a social feed, a messaging app, and a no-code app builder in one place. You post and connect with people like a social network, chat one-on-one or in team groups, and create workspaces where you build your own custom apps, dashboards and tools without writing any code.
