I'm building IOWII, an webapp for sharing money with a partner, family or housemates without merging your whole financial life.
The idea came from my own household: most apps either split bills and nothing else, or want every account in one place. I wanted to share the rent and a holiday fund, and keep everything else mine.
It's in beta, with a free plan and no card needed. I'm launching here soon, and I'd like to hear from people who share money with someone:
how do you handle it today?
What would make you try a new app for shared money, and what would put you off?
