Log spending as you go

The quickest expense tracker is the one you'll use at the till. Start the expense log template: a numbered list of what you spent and a Total line at the end. Type "Petrol 3,000" or "Lunch 650" as it happens; on Android, the Quick note widget opens a new note from the home screen.

Want the maths done for you? Add a table and switch on its totals row, and Memlow sums the amount column as you type.

Totals by category

The monthly budget sheet lists categories such as rent and housing, groceries, transport, bills, phone and internet, eating out, health, savings and other. For each one you type what you planned and what you spent; the sheet works out what's left and the share used. A category that goes over turns red, and the total row adds everything up.

It opens in Memlow Sheets, which has 108 functions. Add SUMIF to total a log by category, or a new column for each week.

Monthly budget sheet

At the start of the month, fill in the Planned column. As the month goes on, update Spent. The column chart puts the two side by side, so one look tells you whether eating out has run away again. Start a new tab for each month and last month stays as it was.

Prefer words to a grid? The monthly budget template is a note with income, fixed costs, spending, savings and a Left over line.

Daily expense sheet for India and Pakistan

Sheet templates show money in your own currency, picked from where your device is, so a phone in Lahore shows rupees. Numbers are read the way your language writes them.

What this tracker doesn't do

Memlow doesn't connect to your bank or read SMS alerts, and it doesn't sort spending for you. You type each amount. That's slower than an automatic app, and it's also why nobody else sees your figures. For tax or accounts, use proper accounting software.

Privacy, in plain words

Your notes stay yours.

No adjectives, just how it works. Memlow's servers never receive your personal notes, so there is nothing of yours for us to read, sell or lose. What you share is stored there encrypted end to end, so only the people you share with can read it.

Read the privacy policy

Where notes live
On your device: the phone's storage, or your browser's own storage on the web.
Accounts
A Memlow account never holds your notes. It keeps only your name, email and how you sign in.
Backups
Optional, in your own Google Drive or a file, encrypted on your device with your password (AES-256-GCM) before they leave it.
Who can read them
Only you. Not Google, not us. That also means we can't recover a lost backup password.
Analytics and AI
The apps have no analytics. This website uses Google Analytics only if you accept it. No AI reads your notes, and the Android app's few ads never see them.
Questions

Good to know

Something else? Look in the Help Center or write to [email protected].

Is this expense tracker free?

Yes. Memlow has no paid plan. The web app has no ads; the Android app shows a few, never in the editor.

Does it connect to my bank?

No. You type amounts in yourself, and they stay on your device or in your own encrypted backups.

Can it show totals by category?

Yes. The monthly budget sheet totals planned and spent for each category and charts them. In any sheet you can also use SUMIF to total a log by category.

Does it work offline?

Yes. Notes and sheets work with no connection on Android, and in your browser after your first visit.

Can my partner and I track expenses together?

Yes. Share the sheet in a notebook and both of you add costs from your own phones, encrypted end to end. Sharing needs a free Memlow account with Google Drive backup on.

Your notes stay yours.

Memlow is free and private, with no AI. Start writing in your browser, or get the Android app.
