Roomsplit: Roommate Expenses

Away half the month? Pay for half the month. The only flat expense splitter that divides a bill by the days each roommate really lived there.

Away for twenty days last month, but still paid a full share of the electricity bill? Roomsplit divides each bill by the days every roommate actually lived in the apartment. Fair to the day, not to the month. No account, no cloud, no subscription.

Shared apartments run on small injustices. One roommate goes home for the holidays, another is away on exchange for three weeks, someone moves in on the 12th, and the internet bill still gets divided in equal parts, because doing it properly means building a spreadsheet nobody wants to build. Roomsplit does that math for you in two taps.

BY DAYS IN THE FLAT: THE SPLIT NOBODY ELSE DOES

• Record each roommate's stays and every bill divides by the nights they were really there.
• Someone away 20 days of a 30-day month pays a third of that month's share, automatically.
• Made for exchange terms, summers back home, mid-month move-ins and rooms that change hands.
• Works on any shared cost: rent, electricity, gas, water, internet, cleaning, groceries.

FIVE WAYS TO SPLIT ANY SHARED COST

• Equally, when everyone used it the same.
• Exact amounts, when you know who spent what down to the cent.
• Percentages, for the big room that pays a little more.
• Shares, when a couple counts double and the small room counts less.
• By days in the flat, for anything tied to a billing period.

SCAN THE RECEIPT, SKIP THE TYPING

• Point the camera at a supermarket ticket and the amount fills itself in.
• Everything is read on your device, so the photo never leaves your phone.

BALANCES THAT END THE ARGUMENT

• One screen shows who owes who, updated the second a shared cost lands.
• Simplified settle-up figures out the fewest payments that clear every debt in the flat.
• Mark a payment as done and the balance closes itself.

INSIGHTS THAT SHOW WHERE THE MONEY WENT

• Total spent by the whole flat and your own share, month by month.
• A spending heatmap and the last eight weeks side by side.
• Breakdowns by category, by roommate and by day of the week, plus your personal records.
• Spot the month the heating quietly doubled before it happens again.

PERFECT FOR

• Student flat shares and halls with a shared kitchen.
• Exchange students splitting a term abroad.
• Young professionals in a house share with people coming and going.
• Couples sharing a place with a third person.
• Anyone who has ever typed "who owes what" into a group chat.

FREE, AND STAYING THAT WAY

• No subscription, and no paywall standing in front of any feature.
