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.

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

Accountability partners

Pick someone you trust. After they text back YES, Luuna lets them know when you're close to your weekly budget, and you can ask them to approve a purchase that goes over.

Luuna's take

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

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.

What can Luuna see?

Only what it needs for your budget, and only inside Smart Shopping Mode.

1

Inside Smart Shopping Mode only

Luuna sees the cart, checkout and order confirmation inside Smart Shopping Mode. Never your browsing history, searches or store-account details.

2

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.

Will it stop me from buying things?

Only if you turn that on. By default Luuna shows you the number at checkout and you decide.
