The expense tracker app that does the tracking for you

Most people can name their rent and their car payment to the dollar, then badly miss on everything else. You estimated $150 a month on delivery. Your bank statement says $487. That gap — between the number in your head and the number in your account — is where money quietly leaves, and it's exactly what an expense tracker is built to close. The old way was to log every purchase by hand or keep a spreadsheet you abandon by week three. SimpleFinances takes a different approach: it reads the transactions your accounts already record and does the tracking automatically, so the real number is on screen without you typing a thing. Most people who use SimpleFinances surface spending they'd lost track of.

What does an expense tracker actually do?

An expense tracker pulls every purchase you make into one place and sorts it, so you can see where your money goes instead of guessing. Rather than remembering to write down each coffee, tank of gas, and online order, a good tracker reads the transactions your bank and cards already record, then groups them into categories — dining, groceries, transport, shopping, bills — and adds up the total for each. The payoff isn't the list; it's the honesty. Spending feels small one swipe at a time, and it's only when a month of small swipes is stacked into a single category total that the picture turns real: the $487 on delivery, the $230 across three streaming services you forgot renew. SimpleFinances does exactly this automatically, then keeps it current, so your spending review reflects this week — not the budget you wrote in January and stopped updating in February.

How does automatic expense tracking work?

Automatic expense tracking works from your real transaction history instead of a form you fill in. When you connect an account through Plaid, SimpleFinances imports your transactions and sorts each one into a category on its own — no tagging, no data entry. As new purchases post to your accounts, they flow in and get categorized too, so the tracker stays current without you touching it. That categorized data becomes your spending review: every category, its total for the period, and where the money actually went. Because it reads what really happened rather than what you meant to spend, it catches the purchases a manual log quietly drops — the tap-to-pay lunch, the annual renewal, the impulse buy you'd rather forget. If you'd prefer not to link a bank, you can enter accounts and transactions by hand and the same categorization and spending review still work. The same data also powers a recurring-charge finder, a financial health score, a net-worth timeline, and a cash-flow calendar.

How does it work, step by step?

Getting your real spending on screen takes three steps. There's nothing to install — SimpleFinances runs in your browser.

How much does an expense tracker cost?

SimpleFinances is free to start. The Basic tier is free forever and lets you connect an account (or enter data manually) and track your spending by category — there's no free trial to remember to cancel, because there's no trial at all. Premium unlocks the full toolkit — the complete spending review, recurring-charge finder, financial health score, net-worth timeline, and cash-flow calendar — for $19.99 a month, or $100 a year. Paying monthly for a year would run $239.88, so the annual plan saves you $139.88 — about 58% off, or roughly $8.33 a month. Because the spending review so often surfaces a category you didn't realize had gotten that big, a year of Premium can pay for itself the first time you act on what it shows you.

Do I have to connect my bank?

No. Connecting a bank makes tracking automatic, but it's optional. If you link an account, SimpleFinances uses Plaid — the same secure service many major finance apps rely on — and the connection is read-only: it can see transactions to categorize your spending, but it cannot move, send, or withdraw money. You enter your bank login with your bank through Plaid, it's never stored by SimpleFinances, and your login stays with the bank. Data is protected with bank-level encryption in transit and at rest. Prefer not to link anything? Manual entry lets you add accounts and transactions yourself, and the same automatic categorization and spending review still work — it's slower to keep current, but your data stays entirely in your hands. Many people start manual to try the app, then link a bank once they've seen what it surfaces. Either way, you see the real number on your terms.

Is a spreadsheet good enough, or do I need an app?

A spreadsheet can absolutely track expenses — plenty of people run one well. The honest question is whether you'll keep it up. Manual tracking is free and fully under your control, but it only captures what you remember to enter, and it goes stale the first busy week you skip. Automatic tracking captures every transaction whether or not you think to log it. Here's the straight trade-off.

The real difference is stamina. A spreadsheet is honest for exactly as long as you keep feeding it; automatic tracking is honest by default, because it doesn't depend on you remembering the $487 in small orders you'd rather not think about. If a spreadsheet already works for you, keep it. If it keeps falling out of date, that's the gap SimpleFinances fills.

What else does SimpleFinances track?

Expense tracking is the front door, not the whole house. Because SimpleFinances already has your categorized transactions, the same data quietly powers the rest of your financial picture. The subscription and recurring-charge finder groups the payments that repeat — so a converted free trial or a forgotten annual renewal shows up before its next bill. A financial health score turns the numbers into one read on how you're doing, a net-worth timeline shows the trend over months, and a cash-flow calendar maps what's coming in and going out so nothing catches you short. It all runs in your browser, on any device, with nothing to download.

However you start — a linked bank or a few transactions typed by hand — the win is the same: you stop guessing at $150 and see the real $487, sorted and totaled without the busywork. Start free, or compare Premium plans.
