The budget app
couples actually use.
Shared envelopes. Both your bank accounts in one place. Two logins. No "why did you spend $80 on lunch" conversations. Free.
They were built for one person.
Most budget apps assume a single user, a single income, and a single bank. When you try to use them as a couple, you end up with one of three bad workarounds: someone gets locked out, you pay for a "premium" upgrade just to share, or you maintain parallel apps that never agree on the numbers.
The other failure mode is apps that DO support couples but make every transaction visible like a tracker. That's how money fights start. Not because anyone overspent — because the act of itemized scrutiny turns spending into a performance.
LazeeFish is built around the envelope method, which solves both: shared envelopes for joint expenses, individual envelopes for personal spending. What's in your fun-money envelope is your business. What's in the grocery envelope is both of yours.
A budget that survives a marriage.
Connect both your banks.
Plaid supports multiple bank connections per account. Link your checking, your partner's checking, the joint account, and the credit cards. All transactions flow into the same envelopes.
Set shared and personal envelopes.
Rent, groceries, utilities, savings — shared envelopes. "Alex's fun money" and "Jamie's fun money" — personal envelopes. Each partner can spend from their own without justification.
Both sign in. Their own login.
Each partner has their own account. Invite them with one link from Settings → Household. Both see shared envelopes in real time — and each person can have private envelopes only they can see.
The three-bucket setup most couples land on.
After enough customer conversations, one structure shows up over and over. It's not the only way to budget as a couple, but it's the one that holds up:
Shared fixed costs
Rent or mortgage, utilities, insurance, internet. The stuff that's the same every month. Funded from the joint account.
Shared variable costs
Groceries, dining out together, household supplies, joint subscriptions. Funded from the joint account, with envelope limits per category.
Personal "fun money" — each
Equal allocation each month from joint into each partner's personal envelope. What you spend it on is your call. No conversation required.
Shared goals
House down payment, vacation, new car. Both partners contribute, both can see progress. Use the savings calculator to set targets.
The key insight: Bucket 3 is what kills the fights. When both partners have a fixed monthly amount they don't have to justify, the entire dynamic of "did you really need that?" goes away. The envelope method makes this explicit and self-policing.

Couples-budget questions.
Can two people use LazeeFish together?
Yes — and each partner gets their own separate login. Go to Settings → Household and send your partner an invite link. They create a free account, join your household, and immediately see the same shared envelopes. No shared-password workarounds needed. No per-user fees ever.
Can we connect both our checking accounts?
Yes. LazeeFish uses Plaid, which supports multiple bank connections per account. Connect both individual checking accounts plus any joint accounts and credit cards. Transactions from all of them flow into the same envelopes.
Should couples have one budget or two?
Most couples do better with one shared budget that includes individual "fun money" envelopes for each person. The shared budget covers rent, groceries, utilities, savings goals; each person's fun-money envelope avoids the "why did you spend $80 on lunch?" conversation. LazeeFish's envelope structure makes this exact split easy. See also: Budgeting for Couples.
How does LazeeFish handle separate finances?
If you keep finances fully separate, you can each create a free LazeeFish account independently. There's no benefit to forcing it onto the same account if your money is genuinely separate. The shared-account model is for couples who pool at least some of their money.
Can my partner see what I spent?
On shared envelopes, yes — that's the point. But you can also create Private envelopes that are completely invisible to your partner. Good for gifts, personal treats, or spending that's simply yours. The system gives you shared visibility where you want it and real privacy where you don't.
Try it as a team.
