Because nobody is watching your bank live. Budget apps get your transactions through a data provider such as Plaid, which typically checks each bank one to four times a day, depending on the bank. On top of that, a purchase starts as pending and usually takes one to five business days to post, so a new charge can take hours to show up and longer to settle.
Below: the three clocks behind every synced transaction, why pending charges move around, why a new or reconnected bank takes longer, and exactly what Spense does and doesn't do about it.
Because each account runs on its own clocks. A transaction passes three of them before it reaches your budget:
Your bank records it
A card purchase shows up at your bank as pending first, sometimes with a temporary amount, and posts once the money actually moves. Plaid says that usually takes one to five business days, and up to fourteen in rare cases.
The data provider checks your bank
Most budget apps don't log in to your bank themselves. A provider such as Plaid checks each bank on its own schedule: typically one to four times a day, depending on the bank.
The app processes what came in
Only after the provider has new data can the app categorize it and redo your totals. A well-built app does this as soon as it is told, but it can only move as fast as the two clocks before it.
With several accounts at different banks, each one is checked on its own schedule, so at any moment one account can be a few hours ahead of another. A transfer between two banks can show up on one side before the other. Nothing is broken; the accounts simply haven't all been checked yet.

A pending transaction is the bank's first note that something happened. When it posts, Plaid removes the pending version and sends the posted one in its place, sometimes with a different amount (a tip added to a restaurant bill, a fuel hold that becomes the real total). To an app, that looks like one row disappearing and another arriving.
In Spense, a pending purchase appears in your transactions marked "Pending Transaction" and doesn't count toward any budget yet. When it posts, it takes the pending row's place: in Auto it is categorized then, and in Classic it waits in Review for you to approve. Your totals only ever include posted transactions. If one lands in the wrong category, here is why that happens and how to fix it.
Because a new bank connection starts from nothing. The data provider has to fetch that bank's transactions for the first time, and the app can only build its reports once that first batch is ready. Until then, a report covering the new account is incomplete, however long it takes.
The connect-a-bank guide walks through linking step by step, and is it safe to link your bank to a budget app? covers what a read-only connection can and can't do.
If you would rather not depend on a bank connection at all, a budget works without one: budgeting without linking a bank shows how. And if you have several accounts, the guide to a budget app without manual entry explains how sync brings them together.
Usually not. Plaid offers an on-demand refresh, but as a paid add-on for the apps that use it, and Spense doesn't use it. Pulling down on Spense's Home screen re-adds what Spense already has; it doesn't ask your bank for anything new.
It was pending and then posted. When a purchase posts, Plaid removes the pending version and sends the posted one, which can have a different amount, such as a restaurant bill after the tip.
Some banks don't share pending transactions at all. Plaid names Capital One and USAA as examples, so a purchase there reaches any app only after it posts.
Not in Spense. Reconnect repairs the same bank connection, so your history stays where it is and nothing is imported twice.
Rocket Money, for example, lists "Real-time sync" as a Premium feature in its own plan comparison. Whatever an app calls it, ask two things: how often it checks your bank, and whether it shows pending purchases. A purchase still has to reach your bank and the data provider first.
