If you used Zeta to manage money with your partner, the easiest replacement is to split its two jobs between two tools: a joint account at a bank you choose for the shared money, and a shared budgeting app for the plan. Zeta bundled both. Now that Acorns has bought Zeta's assets, you can rebuild the same setup in an afternoon, and you don't have to hand an app your bank login to do it.
What happened to Zeta?
In June 2025, Acorns announced an asset acquisition of Zeta, which it described as "a financial planning platform that provides tools and services for couples and families." Zeta's cofounders joined Acorns, and the announcement told existing Zeta customers they were "welcome to join Acorns."
If you'd rather keep what Zeta gave you as a couple, a shared pot of money and one view of the budget you can both see, you can rebuild it yourself.
What did Zeta actually do for couples?
It helps to name the jobs Zeta was doing, so you replace each one on purpose:
- A joint account and cards. Couples who signed up would each get a Zeta joint card and a joint account that sat on top of their existing finances, as TechCrunch described it.
- Shared bills and goals. According to the same article, couples mainly used that account to pay standing bills such as rent or a mortgage, or as savings for goals they shared. Those are banking jobs. What many couples also want is a third one: a shared view of the budget, so nobody has to ask "wait, what was that charge?" That's a budgeting job, and no single app has to do all three.
| What Zeta did | What to use instead |
|---|---|
| Joint account for shared bills | A joint checking account at an FDIC-insured bank |
| Joint debit cards | The cards that come with that joint account |
| Savings for shared goals | A joint savings account, or a second joint account |
| One shared view of spending | A shared budget both partners log into |
Do you even need a joint account?
You don't have to have one, but there's decent evidence it helps. In a study published in the Journal of Consumer Research, 230 engaged or newlywed couples were randomly assigned to merge their money into a joint account, keep it separate, or do whatever they liked, and were followed for two years. Couples who kept money separate, and couples left to their own devices, showed significant declines in relationship quality. Couples who merged everything into a joint account did not show those declines.
The researchers don't tell everyone to rush to the bank, though. Greater Good at UC Berkeley notes that neither lead researcher "suggests everyone should run out and quickly change their bank accounts," and that couples should wait "until both parties really trust the other and are confident in their shared goals." A partner who was hurt financially in a past relationship, or who runs a business, may have good reasons to keep some money separate. One middle ground is a hybrid setup: a joint account for shared bills, personal accounts for everything else. Our guide to budgeting as a couple walks through the options.
Step 1: Open a joint account at a bank you pick
This replaces the part of Zeta that held money. A few things to check:
- Deposit insurance. At an FDIC-insured bank, each co-owner's shares of every joint account at that bank are added together and insured up to $250,000.
- Equal access. For that joint coverage, the FDIC requires that all co-owners "have equal rights to withdraw deposits from the account." That means either of you can move the money, so agree on the rules first.
- Fees and cards. Look for no monthly fee and a debit card for each of you.
Then point your shared bills (rent, utilities, groceries) at that account, the way Zeta couples did.
Step 2: Put both of you on one budget
A joint account shows you a balance. It doesn't tell you whether you're on track for the month. That's the job of a shared budget.
In SimplifyPocket, it works like this:
- One of you opens Settings → Household and invites the other by email.
- Your partner signs in with that email and accepts the invite.
- Once they accept, you share one household: the transactions and budgets you each add. What you'd each already logged comes into the shared household too, so you'll see each other's history, and categories with the same name are merged into one. Worth a quick talk before you pair.
When one of you buys groceries, you log it in a few seconds: tap the mic and say "sixty-two dollars groceries," type it in, or snap the receipt. Your partner sees it on the same budget, against the same "what's left" number. Here's more on adding expenses by voice.
There's no bank connection at any point. Neither of you shares a bank login with the app, which matters when two people share a budget: one partner's comfort level shouldn't decide how much access an app gets to both of your accounts. More on that in budgeting without linking your bank.
Step 3: Agree on who pays what
Zeta made the money part easy because it was all in one place. Without it, you need a simple rule for how much each of you moves into the joint account.
Two common approaches:
- 50/50. Each of you puts in the same amount. Simple, and fair when your incomes are close.
- Proportional. Each of you puts in the same share of your income. Say one partner takes home $4,000 a month and the other $2,000, and your shared bills are $2,400. Together you earn $6,000, so the first partner covers two-thirds ($1,600) and the second covers one-third ($800). Each of you is putting in 40% of your take-home pay.
Write the number down, set up an automatic transfer from each paycheck, and look at the shared budget together once a month.
What SimplifyPocket doesn't do
To be clear about the trade-off:
- It's not a bank. It doesn't hold money, issue cards or move money between you.
- It doesn't link to your bank, so transactions are logged by you (by voice, typing or a receipt photo), not pulled in automatically.
- There's no built-in IOU or "settle up" feature. If you split costs outside the joint account, you'll settle those yourselves.
- A household is two people.
If you want all of that in one app, you'll be choosing a bank product. If you want a clear, shared budget on top of whatever bank you already trust, that's what SimplifyPocket is for.
Common questions
What happened to the Zeta app? In June 2025, Acorns announced an asset acquisition of Zeta and invited existing Zeta customers to join Acorns.
What's a good Zeta alternative for couples? Split the job in two: a joint account at an FDIC-insured bank for shared bills, and a shared budgeting app so you both see the same numbers. SimplifyPocket's household sharing puts two partners on one budget without linking either bank.
Does a joint account help a relationship? In one randomized study of 230 engaged or newlywed couples, those who merged money into a joint account avoided the decline in relationship quality seen in the other groups. Greater Good advises waiting until you trust each other and share the same goals.
Do both partners need to pay for SimplifyPocket? No. One subscription covers both of you once you're paired. See pricing.
