The 5 best apps for shared flats in 2025

Sharing a flat can be a fantastic experience or a constant source of conflict. The difference, often, is organisation. In recent years, several apps have appeared to help — from simple expense splitters to complete cohabitation management platforms. We've reviewed the 5 best.

1. Calyu — The complete, free solution

Calyu is the only app designed from the ground up for shared flat cohabitation. It doesn't just manage expenses: it combines household task management, a shared shopping list, expense splitting and a points system that motivates everyone to contribute. Available in Catalan, Spanish and English, it's 100% free.

• →Task management with automatic assignment and reminders
• →Expense splitting in 5 seconds
• →Real-time shared shopping list
• →Weekly ranking and points system (gamification)
• →Cross-platform: iOS and Android

2. Splitwise — The expense-splitting benchmark

Splitwise is probably the best-known expense-splitting app in the world. It works very well for recording who paid what and calculating debts, but it stops there. No task management, no shopping list, no motivation system.

• →✅ Excellent for expense splitting
• →✅ Detailed payment history
• →❌ No task management
• →❌ No shopping list
• →❌ Full version requires payment

3. OurHome — Basic tasks and expenses

OurHome combines tasks and expenses in one app, which sets it apart from Splitwise. It has a basic points system and shopping list. The problem is that the interface hasn't been updated much and the user experience feels dated.

4. Tricount — Minimalist expense splitting

Tricount is ideal for trips or one-off situations where you need to split expenses quickly among a group. It's simple, visual and free. But it's not a solution for daily cohabitation: no tasks, no shopping list, no long-term tracking.

5. Flatastic — The European alternative

Flatastic offers tasks, expenses and a shopping list. It has a decent interface and works well for small flats. Its weak points are limited gamification and some features being behind a paywall.

Conclusion

If you're looking for an app exclusively for splitting occasional expenses, Splitwise or Tricount do the job well. But if you live in a shared flat and want cohabitation to truly work — tasks, expenses, shopping and motivation — Calyu is the best option, and it's free.
