Budget apps for couples: 7 options for sharing money (2026)

Start with how you share money

Our couples budget guide covers the three main models and how to split costs fairly when incomes differ. Here is what each model means for the app you pick:

• Fully separate. You each keep your own accounts and split shared bills. You need to know who paid what and who owes whom: that's a bill splitter's job, not a budgeting app's.
• Fully joint. One pot, one budget. You need category budgets both of you can see and update, and bank sync can help if all your money flows through the same accounts.
• Yours, mine and ours. A joint account for shared costs plus a personal account each. You need to track the joint account without exposing personal spending, so check what the other person can see.

If you haven't opened a joint account yet, our joint bank account guide explains what it commits both of you to, from overdrafts to what happens after a breakup.

What to check in a budget app for two

If you want bank sync and a shared budget

Prices below come from each company's own site or its US App Store listing, checked on 25 September 2026, in US dollars at the time of writing.

Monarch. A full budgeting and net-worth app on the web, mobile and iPad. Its pricing page lists "Add a partner for free" on both plans, plus read-only access for a financial professional. Core costs $14.99 a month or $99.99 a year; Plus costs $199.99 a year; both start with a free 7-day trial and need a payment method. Suits couples in the US or Canada who want everything, including investments, in one place.

YNAB. Zero-based budgeting ("give every dollar a job"). One subscription can be shared with partners, families and "other close-knit groups of up to six people" for the price of a single subscription: $14.99 a month or $109 a year, after a 34-day free trial. Direct bank import covers select US, Canadian, UK and EU banks, and file import works elsewhere. One plan can't mix currencies. Suits couples who want to plan every dollar together and will sit down weekly to do it.

Honeydue. Built for couples, and free to download (with in-app purchases) on iPhone and Android. Its App Store listing describes seeing both partners' bank balances in one place, monthly spending limits per category with a notification as you approach them, bill reminders, splitting expenses, and reacting to or asking about each other's transactions. It supports "most banks in the US". The Honeydue debit card was discontinued on 1 September 2023, according to the same listing; the app itself continues.

If you want to budget by hand, together

Goodbudget. Envelope budgeting that syncs between devices, on the web, Android and iPhone. The free plan is enough to try as a couple: 10 regular envelopes plus 10 more, 1 account, 2 devices and 1 year of history. Premium ($10 a month or $80 a year) gives unlimited envelopes and accounts, 5 devices, 7 years of history and automatic bank sync for US banks only.

A shared spreadsheet. Free and flexible: one tab per month, one row per expense, a "paid by" column, a SUM per category. It fits couples who like to see the formulas. The weak point is logging on a phone at the checkout, which is where most shared budgets quietly stop.

Binome360. This is our app, so its limits first. It doesn't connect to any bank or import statements, doesn't make payments or transfers, doesn't work out who owes whom and gives no investment advice. It works in English and French.

What it does: you create a shared assistant for the two of you, your partner joins from their own phone, and each of you logs spending in one sentence, by voice or by snapping a receipt. The assistant prepares the entry and nothing is saved until you confirm. You get per-category budgets, shared savings goals, totals kept separately per currency (dollars and pesos after a trip, for example) and recurring reminders, such as the transfer to the joint account on the 1st. Your personal assistant stays yours. It has a free 7-day trial, then costs $3.99 a month, $8.99 for 3 months or $23.99 a year on the web, with every module included.

If you keep your money separate

Plenty of couples, especially early on or in blended families, keep separate finances and simply split shared costs. A bill splitter is the natural tool: each of you logs what you paid and the app keeps the running balance.

Splitwise. Free on iPhone, Android and the web, with free accounts limited to 4 expenses a day according to its help centre. For two people logging rent and groceries, that is usually enough. Its annual "Duo" plan covers two people for Pro features such as search, receipt scanning and currency conversion; Splitwise says its price varies by country. If the cap bothers you, our page on Splitwise alternatives compares Tricount, Settle Up, Splid and Spliit.

A bill splitter answers "who owes whom?", not "how much are we spending on eating out?". If you find yourselves asking the second question, you've outgrown it, and one of the shared budgets above will serve you better.

Set it up in one evening

1. Write your model in one sentence: "The joint account pays rent, groceries, utilities and trips; everything else is personal."
2. Agree contributions, equal or proportional to income. Our guide to running a shared money pot has worked examples for both.
3. Create five to eight shared categories, no more. Too many, and nobody categorises anything.
4. Install the app on both phones and each log one real expense that night.
5. Book the monthly money date: thirty minutes, same day each month, to review and adjust.

Frequently asked questions

What is the best budget app for couples?

There isn't one best app; there is the one that fits your model. Separate finances: a bill splitter such as Splitwise. Joint finances with most money in US or Canadian banks: a synced app such as Monarch, YNAB or Honeydue. Lots of cash or several currencies: a manual shared budget or a spreadsheet.

Is there a free budget app for couples?

Honeydue is free to download, Goodbudget has a free plan on 2 devices, and Splitwise is free within 4 expenses a day. A shared spreadsheet costs nothing. Paid apps usually offer a free trial, from 7 days (Monarch) to 34 days (YNAB).

Can my partner and I use YNAB on one subscription?

Yes. YNAB says a subscription can be shared with partners, families and close-knit groups of up to six people for the price of one.

Will my partner see all my spending?

It depends on the app and on which accounts you connect or share. In a synced app, anything linked to the shared budget may be visible. In Binome360, the shared assistant and your personal assistant are separate. Agree what is shared before you connect anything.

In short

Choose the app after the model: a bill splitter for separate money, a shared budget for joint or hybrid money, and a manual option if your money moves in cash or across currencies. Check that your partner's login is included and that your bank is supported before paying. First step tonight: write down, together, the one sentence that says what your shared money pays for.
