Eight arms, one household

One app does the money. Another does the list. A third does the rota. OctoFlat does all of it in one place, so your household lives in one app instead of four.

Who OctoFlat is for

Two people or six, one flat or three. The list, the costs and the rota work the same way — what changes is which part you lean on.

Couples

Two people, one household, and a running tally in somebody’s head of who paid for the big shop and who covered dinner. OctoFlat keeps the tally instead.

What changes: rent, the streaming subscriptions and the weekly shop split themselves every month, and the balance between you becomes a number you can both look at rather than a conversation one of you has to start.

Families

Several people shop, several people pay, and by the end of the month nobody is quite sure where it went. One list everyone can add to, and one honest picture of the household’s money.

What changes: whoever is nearest the shop can see what is actually needed, chores land with the person whose turn it is without anyone having to allocate them, and the spending breakdown answers the where-did-it-go question with a chart instead of a guess.

Roommates

The hard part of sharing a flat was never the money. It is having to be the person who brings the money up. Balances everyone can already see remove the need for anyone to chase.

What changes: bills are split the moment they are added, the rota is visible rather than remembered, and settling up is a link someone taps rather than a message someone has to word carefully.

Everything a shared household app should do

The things that usually live in a group chat, a spreadsheet nobody updates, and somebody’s memory. Here is each of them, on the screen you will use it on.

Split any bill the way it actually happened

Evenly, by percentage, by shares, by exact amounts, or line by line off the receipt — and correctly even when two people paid towards the same bill. OctoFlat keeps a live balance per person and per currency, so who owes what is a number rather than a disagreement. Settling up is a PayPal link and one tap.

One list the whole household writes to

Everyone adds to the same list and it updates on everyone else’s phone as it happens, so two people do not come home with the same bag of coffee. It learns what your household buys often, which turns the weekly shop into a minute of tapping. Ticked items become a shopping trip, and the receipt links back to it.

A rota that shares itself out fairly

Everyone rates the chores they mind least, once. After that the schedule assigns them — recurring or one-off, morning or evening, and only to the people a given chore applies to. Nobody has to be the person who decides whose turn it is, which is usually the real chore.

Questions roommates and couples actually ask

The things worth knowing before you set a shared household up — money, chores, privacy and moving out.

Is OctoFlat free?

Yes, and the free plan is meant to be lived in rather than escaped from: unlimited members, unlimited households, unlimited shopping lists, plus chores, chat and the calendar. It includes one AI receipt scan a month and a soft daily cap on expenses, both of which reset on their own. Premium lifts the limits and removes the ads. The stores set the price per country, so the app shows you the figure that applies where you are.

Is there an iPhone app?

Not yet. The Android app is on Google Play and the iPhone app is being built. Leave your address on the download page and we will email you once, when it is out.

How long does setting it up take?

A few minutes. Create the household, send the invite link, and add the things that repeat — rent, the internet bill, the streaming subscriptions — once. From then on they turn up already split, and the only thing left to do each week is the shopping.
