Everything your flat actually needs

One cozy app. Every little thing that makes flat life fair.

No more spreadsheets, Venmo guilt trips, or fridge notes. Just the calm systems your flat already wishes it had.

Shared Rules

Editable house rules everyone taps to agree. No more "nobody told me".

Chores & Rotations

Rotating schedules that remind the right flatmate at the right time. Bins, vacuum, bathroom — handled.

Fair Bill Splits

Snap a receipt, Symbio splits it. Power, internet, groceries — always fair, never weird.

Calendar & Reminders

Rent, bins, flat dinners, the landlord visit — all in one shared calendar that actually nudges.

Group Chat

A dedicated flat chat — announcements, memes, and "who ate the last toastie" moments.

You never take the bins out!! I've done it 4 weeks straight 😤

Bro I did it last week, chill. I'll check the rota.

Hey team 👋 Looks like there's a bin-night mix-up. Your flat's rule says "Bins rotate Sun→Sat, whoever's week it is does Tues & Fri."

By the rota: Sam did weeks 1&2, Alex was up last week. A fair fix:

  • 1. Alex covers this Tuesday's bins to even it out.
  • 2. We'll add an auto-reminder 8pm the night before.
  • 3. All good — tea at the next flat meet? 🫖

Calm, empathetic, slightly witty — referencing your flat's rules. No more sticky notes.
