Plinthos

Renting rooms means a WhatsApp group, a spreadsheet, and the calculator app open at once. Someone always forgets who paid rent and who still owes for the gas bill. Plinthos puts it in one place: rent tracked monthly (tenants mark paid with a receipt photo, you confirm), bills split equally, by days or by square meters, deposits handled at check-out, plus chat and deadline reminders. Tenants join free with one link. Built for rooms with multiple tenants, not whole-flat leases.
