Start a one-line spending log
- Step 1Pick one note or notebook you already carry
- Step 2Write one known purchase: amount and what it was for
- Step 3At your weekly glance, compare one category with what you expected
The simplest way to track spending is to write one short line each time you pay for something, right when you pay, and then look at the totals once a week. You do not need a spreadsheet, a budget for every category or a daily routine. You need one place that is always in your pocket, a handful of categories and ten minutes at the end of the week.
Why spreadsheets often stop working
A spreadsheet asks you to do the work later: keep receipts, sit down, type everything in. Later is exactly when tracking tends to stop, because a busy week leaves a pile of receipts and the pile becomes a chore.
Tracking that lasts moves the effort to the moment of spending, when you still remember what the payment was for, and makes that effort tiny. One line typed while you wait for the bus is easier than an hour on Sunday rebuilding the week from statements.
This guide is about seeing where your money goes. It does not tell you what you should spend, and noticing a pattern will not change your situation by itself. It gives you clearer information for the choices you make.
Step one: choose where the line goes
Pick one place you always carry. A notes app, a message to yourself, a small notebook in your bag or the Armored Kitten companion in Telegram all work. Use the same place every time, so you never wonder where last Tuesday's lunch was written down.
Write each line the same way:
Amount, what it was for, and the day if it was not today.
For example: "12 lunch", "45 phone bill yesterday", "8 bus". Short is fine. You only need enough detail to recognise the payment a week later.
Step two: keep the categories few
Many methods start with twenty categories, which turns every coffee into a decision. Start with five or six that cover most of your week, plus "Other".
| Category | What usually goes here |
|---|---|
| Food | Groceries, lunches, takeaway, coffee |
| Transport | Fares, fuel, parking, taxis |
| Bills | Phone, internet, electricity, water |
| Housing | Rent or other housing costs |
| Shopping | Clothes, household items, one-off purchases |
| Other | Anything that does not fit yet |
Split a category only when you have a real question about it. If you keep wondering how much of "Food" is eating out, give eating out its own line. If you never ask, leave the category alone.
"Other" is not a failure. After a few weeks, read what landed there. If the same kind of payment keeps appearing, it may deserve a category of its own. If it is a mix of one-off items, it can stay as it is.
Step three: a weekly glance instead of daily budgeting
Daily reviews are where many people give up. A weekly look is enough to see patterns and short enough to keep doing.
A ten-minute weekly spending glance
- Pick a fixed moment.
Sunday evening or the end of your last workday both work. Attach it to something you already do.
- Fill the obvious gaps.
Check your card or bank record for payments you forgot to note. Add only the ones you can identify.
- Read the category totals.
Which category was largest? Did anything surprise you?
- Ask one question.
"Was that what I expected?" is enough. You do not need a plan for every number.
- Choose one small change, or none.
"Pack lunch on Tuesday" is a change. "Spend less" is a wish.
If you already have a weekly review, make this one line of it. The weekly review template has room for one thing to adjust next week, and spending can be that thing.
A one-week tracking card you can copy
Copy this into a note or print it. Each row is one payment.
| Day | Amount | What it was for | Category |
|---|---|---|---|
| Mon | |||
| Tue | |||
| Wed | |||
| Thu | |||
| Fri | |||
| Sat | |||
| Sun |
At the end of the week:
- Largest category this week: ________
- One payment I did not expect: ________
- One small change for next week, or "none": ________
Example: Daniel's first three weeks
An illustrative example (Daniel is made up): Daniel had started two budgeting spreadsheets and dropped both within a fortnight. This time he set one rule: type the amount and the item into his phone before putting it back in his pocket.
- Week one: He missed a few small cash payments but caught most card payments. Food was his largest category, which he had expected.
- Week two: His weekly glance showed four takeaway dinners, all on days he had worked late. He did not set a budget. He made one change: keep something quick to cook in the cupboard for late days.
- Week three: Two takeaway dinners instead of four. He also spotted a streaming subscription in "Other" that he had forgotten about, and added a note to check whether he still watched it.
Daniel's record had holes, but it showed two patterns he could act on, and that was the whole job.
When you forget to note something
Most advice assumes you record every payment. In practice you will miss some, especially small cash purchases or payments made in a hurry. Here is how to handle gaps without abandoning the habit:
- If you remember it the same day, add it with the right date. A late entry is still useful.
- If you only notice it at the weekly glance, add it from your card or bank record if you can identify it. If you cannot, skip it.
- If a whole week is missing, do not try to rebuild it. Start again from today and treat that week's totals as incomplete.
- If you shared a cost with someone, record only your part. If they still owe you their share, keep that as a separate note rather than counting it as your spending.
- If you get a refund, link it to the original purchase if your method allows, or label it clearly as a refund so the category total still makes sense.
A tracking record describes what you noted. It is not a verdict on you.
Signs your method needs simplifying
If any of these sound familiar, cut something back rather than trying harder:
- You save receipts "to enter later" and the pile keeps growing.
- Choosing a category for a payment takes you longer than a few seconds.
- You skip the weekly glance because it feels like an exam.
- Some of your categories never get looked at.
Remove a step, merge two categories or shorten the weekly glance. A small method you keep using will tell you more than a detailed one you stop.
When tracking shows a bigger problem
Sometimes a few weeks of notes make it clear that more is going out than coming in, or that bills are falling behind. Tracking can make that visible, but it cannot fix it. If you are worried about bills, arrears or debt, contact a free, independent money or debt advice service in your country. They can look at your whole situation, which a list of purchases cannot do.
How Armored Kitten helps you track spending
Armored Kitten is built around one manageable step at a time, and with money that step can be a single message typed right after you pay.
In your private chat with the companion, a message such as "Spent 12 on lunch" or "Paid 45 for phone bill yesterday" becomes a review card. The card shows the amount, a suggested category and your description. It has Save and Cancel buttons, quick category choices (Food, Transport, Bills, Shopping, Housing, Other), a button that switches the day between today and yesterday and a few currency buttons. Nothing is saved until you tap Save, and a saved entry comes with an Undo button. If a message has an amount but the companion cannot safely read it, it tells you nothing was saved.
A few details that help:
- Add "yesterday" or a date written like 2026-11-03 at the end of a message to record another day.
- If you leave out the currency, the entry uses your default currency. Money starts in US dollars (USD). The currency buttons on the card change that one entry; Choose default currency on the card, or Change currency in the Money workspace, changes the default. Saved entries keep the currency they were recorded in.
- Use a clear phrase such as "spent 120 on medicine". "120 lunch" is a supported shortcut. For Filipino-language accounts, "gumastos ako ng 120 sa tanghalian" is also supported. Other phrasings may need correction before review.
- To record money you received, start with "received", such as "received 3500 from salary". Add income in chat in Money shows the same example.
For the weekly glance, ask "How much did I spend this month?" or "How much did I spend on food this month?", or type "Show my transactions" to list recent entries. "Change my last entry to 15" and "Delete my last entry" both ask you to confirm before anything changes.
The Money workspace in the Mini App uses the same records. Start with Log an expense at the top: enter an amount, check the visible currency and choose a category. A note or different date is optional. Tap Review expense, check the details and confirm to save. You can also search and filter entries, correct or delete them, use the full entry editor and download all entries as a CSV file. Optional overall or category budgets and private reminder settings stay in the workspace.
Once Money is on, the companion may also message you in the evening to ask whether you have spending to record. Weekly is enough switches the daily message to a weekly one. The I like this and Opt out buttons appear until you like that message category; after that, both feedback buttons are hidden. To show feedback controls on future check-ins again, open More in the Mini App and remove your like for Money spending check-ins. Use /stop to stop all automatic companion messages.
Some honest limits. Money tracking is part of the optional Plus subscription, and new adult accounts try it during a free trial first. The free tools keep working without it. There is no setup form: once your account has access, Money switches itself on in USD, unless you turned it off or deleted your Money data. It records only what you tell it: the totals are your records, not a bank balance, and Armored Kitten never holds or moves money. You can turn tracking off and keep your records, or permanently delete all of your Money data. If Plus ends, your records stay and you can still download or delete them.
Open Money in the Mini App, with the button at the end of this guide, to look around or change your currency. If most of your food spending happens in one weekly shop, making a grocery list part of your weekly routine pairs well with a Food category.
Questions people often ask
Do I need to track every single payment? No. Aim for most of them. A few missed small payments will not hide a pattern that matters.
Should cash and card payments be tracked the same way? Yes, with the same one-line format. Cash is the easiest to forget, so note it before you put your wallet away.
How long before tracking tells me anything? Give it at least three or four weekly glances before judging whether the method and categories fit.
Do I need a budget to track spending? No. Tracking shows what happened. You can add a budget later for one category you want to watch, or never add one.
