About Expense Tracker
Record what you spend, categorise it, and see the totals build up over a period.
Recording spending changes it, which is the main reason to do it. The effect is well documented in behavioural research: the act of writing a purchase down introduces a moment of deliberation that would not otherwise exist, and some purchases do not survive it. The record is useful, but the pause at the point of spending is where most of the benefit comes from.
Log at the moment of spending rather than reconstructing later. Retrospective reconstruction reliably undercounts, and it undercounts exactly the category people most want to understand โ the small, frequent, unmemorable purchases. Nobody forgets the rent; everyone forgets four coffees.
Keep the categories few. A dozen categories produces precise data you will not review; five or six produces a picture you can actually act on. Everything stays in your browser, so no bank connection or account is involved and your financial detail is not shared with anyone.
How to use Expense Tracker
- Add each expense with an amount and category as you spend.
- Review category totals at the end of the week or month.
- Adjust based on what the totals show rather than what you assumed.
Frequently asked questions
Does tracking spending actually change it?
Generally yes. Writing a purchase down adds a moment of deliberation that some purchases do not survive. The pause at the point of spending tends to matter more than the record itself.
Should I log as I go or at the end of the week?
As you go. Reconstructing later reliably undercounts, and it misses the small frequent purchases that are usually the ones worth understanding.
How many categories should I use?
Five or six. Highly detailed categorisation produces precise data nobody reviews; a handful of broad categories produces a picture you can act on.
Is my financial data private?
Yes. Everything is stored in your browser on this device with no bank connection and no account. Nothing is uploaded.
