The idea is also to merge in a single app many needs of events, like group chats, photo albums, expenses splitting, and I'm planning to add more. I realized groups have similar needs to events, so I added them as well (think small private groups, not massive communities).
All of this is stil very early in development and it definitely needs some more work before a Show HN, but we've found it very useful for weekends and holidays already.
Consider it an open beta, so feel free to give it a try and give me your honest feedback :)
