What Luuna is

Most money apps are autopsies.

They tell you, on the first of the month, that you spent $847 on food delivery. They show you a pie chart. They suggest, gently, that maybe next month could go differently. By the time you read it, the money is gone and the version of you who spent it is gone too.

The decision didn’t happen in the dashboard. It happened at 11:47pm in the DoorDash cart, when you were tired and the tip slider was already at 25%.

Luuna is built for that moment.

It runs on your phone, reads what’s in front of you in the apps you already shop in, and — when something’s about to happen that you’d probably regret — it shows up. Not with a lecture. Not with a block. With a small, quiet pause that says here’s what you’ve spent on this category this week, here’s what you said you wanted to do, here’s the override button if you still want the thing.

You usually still want the thing. That’s fine. Luuna’s not trying to win.

What it’s trying to do is move the point of intervention from the monthly recap to the actual moment of decision — which is the only place a decision can be changed.

We’re building this because every other tool in this category treats spending like a data problem. It’s not. It’s a moment problem. Data alone never changed anyone’s behavior; a friend tapping you on the shoulder at the right second, every time, can.

We’re in private TestFlight on iOS. The first 1,000 people get a numbered Founding Member badge and a price locked for life — set when we open pricing publicly later this year. We’re letting people in by cohort because the model gets smarter the more carefully we onboard, and we’d rather a slow good thing than a fast mediocre one.
