3000Diary

One family.
One ledger.

Real Money. Real Life. A Brighter Tomorrow.

Say it and it's logged. Who spent it, and whether it belongs to the whole family or to one person — the app sorts that out. Shared costs like hydro get split across everyone automatically.

The hard part was never the math

Say it, and it’s in

Tell your phone "Starbucks, six eighty" — amount, merchant and category fill themselves in. Typing works too, but talking is faster.

See who spent it at a glance

Everyone in the family gets a colour, taken from the four digits in the wordmark. Scanning a month of expenses no longer means reading names line by line.

Shared costs split themselves

Hydro bill of 180, four people, 45 each — done the moment you log it. You decide how many shares the kids count for.

Shared or personal

It decides for you.
One tap fixes it when it’s wrong.

Groceries belong to the family; that coffee is yours. The app makes that call for you — and once you've corrected it, it remembers how your household does things.

  • Groceries, hydro, mortgage → shared by default
  • Coffee, games, clothes → personal by default
  • Corrections stick, so it gets better as you use it

Weekly and monthly

The whole family,
and each person in it

Reports come out every week and every month. What the family spent, what each person spent, how the shared costs were split — one chart covers it.

When you want to show the kids, this chart works better than a lecture.

Every family's ledger is fully isolated
Only your household can see your data. Other families use the same app without the data ever mixing — and that separation is enforced by the database itself, not by application code remembering to behave.
