Know where your
money goes.

Lunas turns your income, bills and savings plan into one simple number — and then keeps it honest as the month goes on.

Free while in early testing. Works on one device without an account.

The whole app, as it is

Four screens, photographed from the build that is live right now. Not mockups — if the app changes, these change with it.

Today — the one number, and what it is made of
Plan — income, commitments and savings, all editable
Worth — what you hold against what you owe
Insights — where the money actually went

One number, and where it comes from

There is no clever model here and nothing hidden. Lunas subtracts what is already committed, sets your savings aside first, and divides what is genuinely left across the days remaining. Every screen in the app reads that same calculation, so no two figures can disagree.

Change a bill, and today’s number changes with it immediately.

The same figures as the phone above. They reconcile because the app refuses to let them do anything else.

What Lunas does

Add in seconds

Log what you spent in a couple of taps, in any currency. Lunas keeps the original amount and the rate, so a trip abroad still reconciles later.

Savings stay yours

Your goals come off the top, not out of whatever happens to be left. The daily number already has them subtracted.

Works with no signal

Everything is written to your device first and catches up later. A bus with no reception is not a reason to stop tracking.

No bank login. Ever.

Lunas never asks for your online banking credentials. You tell it what you earn and what you owe; it does the rest. Your figures are written to your own device first, and if you never create an account they never leave it.

Sign in only if you want the same plan on your phone and your laptop. There are no passwords to store, you can export everything you have put in at any time, and deleting your account deletes the data with it.

Something not adding up?

Lunas is in early testing, and a figure that looks wrong is worth telling us about — it is how the engine gets checked against real money rather than our own examples. Write to lunas@kapix.io.
