Project overview
HomeFlow was designed around a simple everyday problem: shared household information is often spread across messages, notes, banking apps and separate shopping lists.
The goal was to create one shared space where household members can keep track of expenses, shopping and everyday organization together.
Summary
- Mobile application
- Shared household
- Expense tracking
- Shopping lists
- Collaborative data
- Cross-platform
The problem
Shared household tasks are simple individually — but fragmented together.
- Expenses may be tracked separately.
- Shopping lists may live in messages or notes.
- Household members need shared visibility.
- It should be easy to see who paid for what.
- Everyday information should not require multiple apps.
- The experience needs to remain lightweight and fast.
- Shared data should stay synchronized across users.
