Casamates is a free app for people who share a home. It helps flatmates, roommates, couples, families, and co-living households keep everyday house admin in one place.
Track and split shared expenses, see who owes what, settle payments, create shared or private shopping lists, assign one-off or recurring chores, and plan together with a shared household calendar. Housemates can join by invite link or QR code, and real-time updates keep everyone in sync.
Casamates also includes free web tools for shared living: a rent split calculator, roommate agreement generator, and deposit deduction estimator with UK and US dispute letter support.
The goal is simple: replace scattered group chats, notes, spreadsheets, and awkward reminders with one calmer way to run a shared home.
