DayBank - Daily Budget Tracker

DayBank - Daily Budget & Rollover Spend Tracker with Streak Goals.

One number. Every day. Whatever you don't spend rolls to tomorrow.
DayBank gives you a daily spending limit and a simple rule: stay under it and the difference carries forward as a bonus. Go over and tomorrow adjusts. Your balance is always honest.

HOW IT WORKS Set a daily budget or monthly budget. Every morning your spending tracker resets with a fresh allocation. Unspent money rolls over automatically. Overspend and tomorrow gets a little less. No bank sync — you log it manually, so you feel it.

BUILD YOUR STREAK Stay under your daily budget every day and your streak grows. Overspending resets it to zero. The longer your streak, the stronger your money habit. Log every expense and watch the habit form.

SEE YOUR MONEY MOVE WITH FLOW. Most budgeting apps hand you charts. Flow gives you a feeling. Your cushion rises and falls like a tide — amber when you're ahead, coral when you've dipped below. Scrub through your spending day by day, pinch to zoom out to weeks and months, and get plain-language insights that tell you something you couldn't see yourself. All computed privately on your iPhone.

ASK YOUR MONEY. Type a question. Get a real answer. "What did I spend on coffee this month?" "How's this weekend compared to last?" "Am I ahead of last month?" Ask anything, in your own words, and DayBank answers with the actual number — not a guess.
Ask is built on Apple's on-device Foundation Models framework. The model's only job is understanding your question; DayBank's own code does every calculation, so the numbers you see are always exactly right. Every answer shows precisely what it understood, so you're never left wondering.
No chat logs. No cloud. Nothing you ask ever leaves your iPhone.

SPREAD for the expenses that don't fit in a single day
Life doesn't always budget neatly. A car repair, a new laptop, a dentist visit — sometimes a cost is real and it's now, but it doesn't have to wreck an entire day.
Spread lets you take any large expense and borrow it from your future self. Pick a window — a week, a month, up to 90 days — and DayBank silently deducts a small fixed amount each day until the balance is settled. Your arc reflects it, your widgets reflect it, your streak tracks against it. Nothing else to configure.
The math is simple: $300 over 30 days is $10 off your budget each day. That's a day you can still live normally.
Find it in Planned Expenses. Spread is part of DayBank Pro.

JARS fill one up, a day at a time. A trip in August. A new phone. Concert tickets. Jars turn a far-off expense into small daily moves: create a jar, then add to it whenever it suits you — $30 from a quiet day, $100 spread over an easy week, $500 over a month. DayBank quietly trims each day's budget, and the jar fills up.
When the day comes, release it — the whole amount lands back in your daily budget, rolling forward as you spend, just like the rollover you already know. Take out only what you n
