Know where the money goes.

Daybook scans your receipts, tracks your budgets and works out who owes you what — on your iPhone, with no account and nothing sent anywhere.

Coming to the App Store. Free, no account. iPhone, iOS 15.5 or later.

Daybook's home screen for August 2026: RM1,067.20 spent this month, down 74.1% on last month, with income, net and daily average beneath it. Below that, RM142.00 owed to you from one person, three bills due soon including rent, and the monthly budget ring.

Most finance apps ask for your bank login. Daybook asks for nothing at all — there is no sign-up screen, because there is nowhere to sign up to. Your records, your receipts and every figure stay in the app's own storage on your iPhone. We never see them, and we could not retrieve them if we tried.

Scanning

Point the camera at a receipt. The rest fills itself in.

The merchant, date, total, tax and every line item are read on your phone using Apple's Vision framework — the same technology iOS uses to select text in a photo. Nothing is uploaded to be read.

The category is suggested from what you scanned before, so the coffee shop you go to every morning is categorised correctly by the second visit. Anything the scan is unsure of is flagged for you to check, rather than quietly accepted.

It reads 19 languages, including Bahasa Malaysia, Chinese, Japanese, Thai and Arabic.

Features

Built for how money actually moves

Budgets that behave

One monthly ceiling and per-category limits. Unspent budget can roll over, and a pace projection tells you where the month is heading before it gets there.

Real credit-card cycles

Cards bill in cycles, not calendar months. Daybook keeps this statement's balance apart from spending that lands on the next one, and nudges you the day the statement closes — not the day before payment is due.

Never pay late

Recurring reminders for bills, subscriptions and card payments. Marking one paid records the payment and rolls the schedule forward.

See where it went

Monthly reports, category breakdowns, top merchants, this month against last, and a six-month trend.

Locked, and private

Face ID, Touch ID or your passcode to open the app — and a cover that hides your balances in the app switcher.

Your data, portable

CSV and JSON export, full backups including every receipt photo, and CSV import from whatever you used before. All free.

A look inside

Every screen below is the real app, in its dark theme. Light theme is there too.

The Records ledger grouped by day, showing a scheduled repayment, a shared sushi dinner split down to RM142.00 of RM426, and everyday expenses at Tealive, Watsons, Guardian and Starbucks with their categories and accounts.

Records

Every expense, income and transfer, grouped by day.

The Budgets screen: a ring showing 24% of the monthly budget used, RM3,432.80 left of RM4,500.00, a daily allowance of RM137.31, and a projection of RM4.7k which is flagged as over budget. Below, per-category limits with Shopping already over at RM259.00 of RM200.00.

Budgets

A ceiling, per-category limits, and where the month is heading.

The Reports screen for August 2026: RM1,067.20 total spent, down 74.1% on July, and a donut chart breaking spending down by category — Shopping 24%, Groceries 17%, Utilities 13%, Fuel 11%, Phone and Internet 9%, Food and Dining 7%, Personal Care 6%, and a neutral Other wedge at 12%.

Reports

Where it went, by category, with a colour-vision-safe palette.

The Reminders screen: RM1,800.00 of monthly commitments across three active reminders — rent due in two days, a Visa Platinum payment of a varying amount due in five days, and car insurance due in nine — each with a Mark paid action.

Reminders

Bills, subscriptions and card payments before they fall due.

Owed to you

Paying for other people is lending, not spending.

A RM 300 dinner for three leaves your account short by 300, but only 100 of it is your spending. Daybook is the only tracker that keeps those two figures apart: your budget sees 100, your balance sees 300, and 200 sits under Owed to you until it comes back.

Owed to you

A receivable, not an expense

RM 200

The Owed to you screen: RM142.00 outstanding across one person. Wei Ming still owes RM142.00 on one unpaid item, while Aisyah's RM142.00 is listed as settled up.

Or split it by item, straight off the scanned receipt

Split evenly, by shares, by percent, by exact amounts — or by item. A receipt's lines never add up to its total; there is always a service charge or tax in between. Charging someone only the price of their dish would leave you covering everyone's tax, so Daybook shares the gap in proportion.

A RM 30 steak and a RM 20 pasta on a RM 58.30 bill: RM 34.98 and RM 23.32. The steak carries 60% of the service and tax, because it was 60% of the food.

Bill totalRM 58.30
ItemPriceShare of gapOwed
SteakRM 30.0060%RM 34.98
PastaRM 20.0040%RM 23.32

RM 8.30 of service charge and tax sits between the items and the total. It is shared in proportion rather than left with whoever paid.

For sole traders

A second set of books, kept genuinely apart.

Business spending gets its own accounts, budgets, categories and reports. Nothing crosses over, so a client lunch never lands in your personal food budget — and neither shows up in the other's totals. Switch between them in a tap.

Produce a statement as a PDF or spreadsheet when it is time to be paid or to file.

Built by Cortex Solution

A product you can check

Daybook is built and maintained by Cortex Solution, a software team in Ara Damansara that also builds custom software and automation for Malaysian businesses. “No server” is a claim you are right to be sceptical of, so here is exactly what the app does and does not do.

  • Every record and receipt in the app's own storage on your iPhone
  • No sign-up, no login, no cloud sync, no analytics SDK
  • One network request in the whole app: an exchange-rate lookup you trigger by hand
  • Biometrics handled by iOS — the app is told only whether it succeeded
  • Deleting the app deletes all of it, permanently

Free, properly.

Recording, scanning receipts, budgets, monthly reports, reminders, splitting bills, importing, CSV export and backups are free — and stay free. A finance app that holds your own records hostage is not one worth recommending.

Daybook Pro

Adds a second set of books, the longer view of your spending, statements as PDF or spreadsheet, and every receipt photo kept indefinitely.

Nothing to cancel

All three unlock exactly the same things — there are no tiers inside Pro. Malaysian and US prices are shown; the App Store sets its own price point in every other territory, so the figure you see at checkout is the one that applies.

The Insights report: heading for RM4,726.17 this month, 121% above the usual RM2,136.66; a typical month of RM4,120.00; average spend per weekday against per weekend day; and which categories are creeping up or easing off over the last three months.

Frequently asked

Do I need an account?
No. There is nothing to sign up for, because there is nowhere to sign up to. Open the app and start recording.
Where is my data stored?
On your iPhone only, in the app's own storage. It never leaves the device unless you export it yourself. See the privacy policy.
Does it connect to my bank?
No. Daybook records what you tell it. Nothing is imported from a bank, and no bank credentials are ever requested.
Can I get my data out?
Yes, always. CSV and JSON export are in Settings, along with a full backup that includes every receipt photo. All free.
What if I lose my phone?
With a backup, restore in a tap. Without one, the records are gone — we have no server and no copy. Keep a backup in iCloud Drive.
Is there an Android or iPad version?
Not yet. Daybook is iPhone-only for now.
