What's the one thing about sharing a home that still drives you up the wall?

Jhozy launches here tomorrow. It's an app for couples, families and roommates to share expenses, the shopping list, chores and a calendar in one place.

Before we go live, I'd love to hear from anyone who shares a home: what's the recurring friction you still haven't solved? Splitting bills fairly, the grocery list living in five group chats, whose turn it is to take the bins out...

I'll read every reply, and the most common ones will shape what I build next.
