Quick answer
A daily cash flow app shows how much money you have available for today after upcoming bills, recurring payments, and recent commitments. Pip calls this Spendable Cash Today, a single number to check before spending. Pip is read-only, does not move money, and does not store your bank username or password. Instead, it reads your account data securely and gives you a simple number for today's spending, so you can avoid overspending without categories, spreadsheets, or guilt.

How to estimate it
To calculate daily cash flow yourself, start with your checking balance and subtract everything already spoken for. The basic formula is:
Estimated spendable today = usable cash – near-term bills – protected savings – already-committed card/debit spending – other known obligations.
You would list upcoming rent, utility bills, credit card payments, and any transfers to savings you want to leave untouched. You'd also need to remember recurring subscriptions that hit mid-week and debit card swipes that haven't cleared. Then subtract those from your balance. Doing this by hand is slow, easy to forget items, and tedious to repeat every day. Pip automates the subtraction so you can see how much you can spend today without opening a spreadsheet.
Here's an example of how the calculation works on a typical Thursday.
The result is an estimate, not a precise balance, because transaction timing, pending charges, and unexpected bills can shift the number slightly. Pip refreshes the figure each time you open the app so you are always working from recent data.
What can make this estimate wrong
Any daily cash flow estimate has limits. If you haven't connected all your accounts, or a connected account has a refresh delay, the number won't reflect your full picture. Pending transactions, refunds, and unexpected bills can also affect the estimate. For example, a card hold from a restaurant or a doctor's visit that hasn't posted yet can make your balance look healthier than it really is. If a savings transfer is scheduled to leave your checking tomorrow but the data feed lags, the app might not deduct it in time.
Pip cannot predict future income, windfalls, or bills you haven't entered. Spendable Cash Today is a decision-support shortcut, not a guarantee. The app does not store bank usernames or passwords, cannot move money, and depends on timely data feeds, so treat the number as your daily starting point, not an absolute rule.
How Pip handles it
Pip connects to your bank accounts through a read-only data aggregator, so it can list balances and transactions without ever moving money or storing your login credentials. Once linked, Pip groups near-term obligations, including recurring subscriptions, upcoming bill payments, and committed card spending, and subtracts them from your total available cash. The result is Spendable Cash Today, updated each time you open the app. You can check it once a day before spending, without managing categories, building a budget, or tracking every purchase.
Pip uses the same estimation logic as many simple finance apps without budgeting, but it's designed for people who want a simple companion, not a dashboard. Instead of charts and projections, it gives you a single answer to the question "what can I actually spend right now?" For a deeper dive, visit How the number works.
Before you rely on the number
Use the daily figure as a checkpoint, then pause for anything the app may not have seen yet. Look at bills due before the next payday, recent card activity that may still be pending, and transfers you already promised to savings. If one of those changed today, keep a little extra buffer in mind. Pip is built to make that pause faster by keeping the view small and read-only, but the final spending decision still belongs to you.
FAQ
What is a daily cash flow app?
A daily cash flow app gives you a real-time sense of what money is available for today, after subtracting upcoming obligations. Instead of showing only a raw bank balance, it applies a simple cash-flow lens: how much is truly free for today's purchases. Pip delivers this as Spendable Cash Today, a read-only number that helps you decide whether a little treat or an impulse buy is available for today, without locking you into a budget.
How does Pip calculate my daily spending number?
Pip looks at your connected checking account balance, identifies upcoming bill payments and subscriptions within the next several days, and subtracts any protected savings or already-committed debit card spending. The calculation runs automatically each time you open the app, using recent transaction patterns and known obligations. There's no manual entry needed, and Pip does not move your money; it only reads data to produce your daily number.
Is Pip safe to connect to my bank?
Yes. Pip uses bank-grade encryption and industry-standard data aggregators to provide a read-only connection. It never stores your bank username or password, cannot initiate transfers or payments, and is not financial advice. Your accounts remain under your control, and the app cannot move money, so you can check your number with confidence.
