Your budget comes shopping with you.
Give each store you shop a weekly number. Luuna keeps what's left of it at the top of every page and checks every order against it before you pay. There's nothing to log, so it doesn't fall apart in week three like the budget apps you quit.
Step 1 of 4
Give your stores a weekly budget
Start with the ones you spend the most in, say $45 a week at Amazon and $30 at Walmart.
- A number for each store you shop
- Amazon, Walmart, Target, Uber Eats and DoorDash
Step 2 of 4
Shop in Smart Shopping Mode
Open the store from Luuna or its home-screen widget. What's left for the week stays pinned to the top while you browse.
- Opens from the app or the widget
- Your number on every page
Step 3 of 4
See where an order leaves you
At checkout Luuna shows the order total, what you have left and where you'd land. Then you choose to wait on it or carry on.
- The real number before you pay
- You decide what happens next
Step 4 of 4
Watch what you keep add up
Money you didn't spend shows up on your Home screen, and each week under budget adds to your streak.
- What you kept, on your Home screen
- A recap every Sunday evening
Run your own numbers
What do one-tap orders cost you in a year?
That's what your one-tap orders add up to in a year. Keep just one in four and that's $1,248 toward a trip.
The math runs in your browser and nothing is sent anywhere. An estimate from the numbers you entered, not a promise of savings.

Luuna's take
This is the third pair of headphones you've looked at tonight. Maybe sleep on it before adding this one.

Built for the moment before you pay
Tap the budget pill on any page for a quick read on what you're looking at.
Lock the shopping apps you open without thinking. Tap one and Luuna opens that store in Smart Shopping Mode instead, with your budget at the top. Core locks up to three apps, and Max locks as many as you like.
Every Sunday evening you get a short recap: what you kept and how many of your stores stayed under budget.
Connecting a bank is optional. It lets Luuna count what you spend outside the app, so your weekly numbers stay accurate.
Your call
The final say is always yours.
Luuna won't block a store unless you ask it to. It puts the real number in front of you and then gets out of the way. If you still want the thing, buy it.
Get early accessWhat can Luuna see?
Only what it needs for your budget, and only inside Smart Shopping Mode.
Your bank stays optional
Connecting a bank lets Luuna count what you spend outside the app, so your weekly numbers stay accurate. Skip it and Luuna still works.

What testers say after their first weeks
OUTCOME QUOTE IN THEIR WORDS
FIRST NAME · CONTEXT (e.g. grad student, DoorDash regular)
Every budgeting tool we tried showed up afterward with a chart. A budget like that is an autopsy. So we built Luuna for the moment before you pay.
Take the moment back.

- Come back and tap Install Luuna.
That's it: no invite to wait for. If the current group is full, leave your email and you're first in when the next one opens.
How stable is the beta?
It's a beta, so you'll hit rough edges. We change the app every week, and every change is on the changelog with its date. Found something broken? Take a screenshot and share it with TestFlight's feedback, or email info@tryluuna.com.
When does the beta end, and what does Luuna cost after?
We haven't set an end date yet. Luuna is free for as long as you're in the beta. We'll post the price here before Luuna opens on the App Store, and Founding Members, the first 1,000 people to download Luuna and sign in, keep a discount on it for life.
Who is Luuna not for?
If you want to plan every dollar of the month, track bills across all your accounts or look back at charts of where your money went, a full budgeting app like YNAB does that better. Luuna is for the order in front of you, in the few stores where one-tap orders add up. It's iPhone only for now. How Luuna compares
Is there an Android version?
Not yet. Luuna is iPhone only for now.
