The 7 Best Flatmate Management Apps in Europe (2026)

Living with flatmates is a universal experience across Europe — from WGs in Berlin to pisos compartidos in Barcelona to colocations in Paris. And wherever people share a home, the same problems pop up: who paid for groceries, whose turn is it to clean the bathroom, and why is the milk always gone.

Thankfully, there's no shortage of apps to help. But which ones actually work for the European market? We've tested the most popular options and ranked them based on features, usability, multilingual support, and pricing.

1. HouseKeepr — Best All-in-One Solution

What it is: A complete flatmate management platform covering expenses, tasks, shopping lists, house rules, polls, bookings, and real-time chat.

Why it stands out: While most apps focus on one thing (usually expenses), HouseKeepr is built for everything that comes with shared living. It's the only app on this list that handles expense splitting AND chore rotation AND house rules AND democratic voting — all in one place.

Key features:

• Expense splitting with automatic balance calculation
• Task management with rotation and reminders
• Synchronized shopping lists
• House rules with read confirmation
• Polls for group decisions
• Guest management and resource bookings
• Move-in/move-out workflows
• Real-time chat
• 6 languages (EN, ES, FR, DE, IT, PT)
• PWA — works on any device

Pricing: Free tier available. Premium for advanced features.

Best for: Flats that want one app to replace WhatsApp + Splitwise + Google Calendar + shared notes.

2. Splitwise — Best for Pure Expense Tracking

What it is: The most popular expense-splitting app worldwide.

Why it's good: Splitwise does expense tracking extremely well. It's mature, polished, and your flatmates probably already know how to use it. Multi-currency support is great for international flats.

Key features:

• Expense splitting (equal, by amount, by percentage)
• Debt simplification
• Receipt uploads (Pro)
• Multi-currency with automatic conversion
• PayPal/Venmo integration

Pricing: Free basic. Pro at $3/month or $29.99/year.

Limitations: Only covers expenses. You'll need other apps for tasks, cleaning schedules, and communication.

Best for: Flats that only need expense tracking and nothing else.

3. Tricount — Best for Simplicity

What it is: A lightweight expense-splitting app popular in Western Europe, especially France, Belgium, and Spain.

Why it's good: Tricount is dead simple. No account required — create a group, share a link, start adding expenses. The UI is clean and there's almost no learning curve.

Key features:

• No-account group creation
• Simple expense entry
• Offline mode
• Fair split algorithm (minimizes transactions)
• Available in 10+ languages

Pricing: Free. Premium at ~€3/month for receipt photos and stats.

Limitations: Very basic. No tasks, no lists, no rules, no chat. Even the expense features are simpler than Splitwise.

Best for: Short-term shares, casual groups, or people who hate signing up for things.

4. OurFlat — Best Basic All-in-One

What it is: A flatmate app covering expenses, shopping lists, and chore schedules.

Why it's good: OurFlat tries to be an all-in-one solution and covers more ground than pure expense apps. The chore scheduling and shopping list features are useful additions.

Key features:

• Expense tracking
• Shopping lists
• Cleaning schedules with calendar
• Polls
• Chat

Pricing: Free with ads. Premium removes ads and adds features.

Limitations: Less polished than specialized apps. The expense tracking isn't as robust as Splitwise, and the feature set is narrower than HouseKeepr.

Best for: Flats that want more than expense tracking but don't need a full management platform.

5. Settle Up — Best Multi-Platform Support

What it is: An expense-splitting app with broad platform support (iOS, Android, Windows, Web).

• Multi-currency support
• Debt simplification

Key features:
