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.
Maker here. This one started at a family dinner. My aunt rents three rooms in a flat to students, and her whole system was a WhatsApp group, a notes file, and the calculator app on her phone. Every time the gas bill came in she'd lose an evening working out who owed what, then chase three people for screenshots of bank transfers. Half of them she never got back.
I kept saying "there's probably an app for this," and there honestly wasn't. Everything I found was built for renting a whole apartment to one tenant on one lease. Nothing understood that one flat can have a double room, two singles, four people, and four different rents that all need splitting when a bill lands.
So I built Plinthos around the room instead of the flat. Single, double, triple rooms, priced per bed or per room, occupied vs total beds tracked. Rent is generated each month, the tenant marks it paid with a photo of the receipt, and you confirm or reject. Bills split equally, by square meters, or by days someone actually lived there. Deposits get a real check-out flow with deduction notes and damage photos. There's chat for the whole flat plus private DMs, and reminders before contract and tax deadlines.
The owner pays after a 14-day trial. Tenants are free forever and join with one link. My aunt's tenants were on it the same evening.
It's on iOS, Android and web, works across countries and currencies, in five languages. If you've been the landlord OR the roommate chasing everyone for bill money, what did I miss?
