Zero-based budgeting, one day at a time

Budget by the day.

One number each morning: what's safe to spend today. Dayfund is the zero-based budget you check every day. It works at the level you spend, not the level you get paid.

Founding members lock in $59/year with bank sync for as long as they stay subscribed. No card needed to join.

Dayfund's Today screen: $43.50 safe to spend today out of $67, with a week chart showing Monday and Tuesday under budget and Wednesday over.

The budget you check every day

Monthly budgets tell you on the 30th that the grocery money ran out on the 12th. Dayfund keeps the zero-based method and answers the question you actually have each morning.

  1. Give every dollar a job

    Assign the money you have to categories until Pending assignment reads zero.

  2. Pick each category's rhythm

    Groceries weekly, rent monthly, gifts yearly, all in one budget.

  3. See today's share

    Dayfund splits each job into a daily share and adds them up into Safe to spend.

  4. Spend with confidence

    Under today? The rest stays in the category. Over? You see it the same day, not at month's end.

Today

Spend with confidence today

Open the app and the first thing you see is how much is safe to spend today, with the week drawn underneath: green days stayed within their share, red days went over.

  • Choose which categories count, like groceries, dining out and fun money
  • A tip each morning when a category is running ahead of its pace
  • Day, week, month, quarter, half-year and year views of the same budget
  • Light and dark mode, following your phone
The Today screen in dark mode: Safe to spend, items needing attention and a tip for today.
Planned

Irregular bills stop being surprises

Car insurance due in March? We set aside a little each month and tell you if you fall behind. Yearly and one-time costs are judged on pace, so a bill months away never shows up as "underfunded".

  • Every 6 months, every year, or just once by a date
  • One tap assigns this month's set-aside for all of them
  • An alert only when you're behind and it's due within 30 days
The Planned screen: holiday gifts, car insurance and a summer trip, each with an amount to set aside this month and an On track or Behind pace label.
Receipts

Know what things cost

Snap a receipt and Dayfund splits it across your categories, then remembers each item. See what you spend on coffee each month, and that eggs are 60 cents cheaper across town.

  • Tax and tip spread across the lines so every cent adds up
  • Unit prices by store, and a heads-up when a regular item gets pricier
  • Photos are deleted 90 days after you save the receipt
The Items screen listing a month's grocery spending by item: salmon, chicken breast, coffee, olive oil, eggs and more.

Built for how households really budget

Budget together

One budget, two logins, no spreadsheet handoffs. Your partner's login is free.

Private by design

Your numbers stay yours. Each household is walled off inside the database, we never sell data, and insights run on rules, not on a chatbot.

Bring your bank's history

Import your bank's CSV file and Dayfund matches what's already there, learning your payees as you go.

On every device

Works in any browser on iPhone, Android or a computer, adds to your home screen, and keeps working offline.

Two plans, one budget

The only difference is automatic bank sync. Start manual and add bank sync anytime. The private beta is free, and waitlist members keep the founding price.

Questions

When can I start using Dayfund?

We're inviting the waitlist to a free private beta in small waves, so we can talk to everyone who joins. Paid plans start after the beta; bank sync comes with Dayfund Connected.

Does it connect to my bank?

In the beta you add transactions by hand or import your bank's CSV export. Automatic bank sync comes with Dayfund Connected when paid plans open.

I already use YNAB. How is this different?

Same zero-based method: every dollar gets a job. Dayfund then works at the level you spend: a daily share for each category, a Safe to spend number for today, and irregular bills judged on pace instead of flagged as underfunded.

Is there an iPhone or Android app?

Dayfund runs in the browser on any phone and can be added to your home screen like an app. Native iPhone and Android apps come after the paid launch.

What happens to my data?

Each household's data is separated inside the database itself, so one household can never see another's. We don't sell data or show ads. Insights are computed by rules on our servers; a receipt photo is read by an AI model only when you scan one, and the photo is deleted 90 days after you save it.

What does the founding price include?

Dayfund Connected, bank sync included, at $59 a year instead of $89. Prefer manual? Founding Essentials is $39. Either price stays as long as your subscription stays active.

Can I switch plans?

Yes, anytime. Upgrades start at once; downgrades start at the end of what you paid for. Nothing you entered is deleted: after a downgrade your bank accounts stay, with all their history, as manual accounts.
