For H-E-B and Kroger shoppers in Texas
Five dinners a week from this week's sales at your store.
CartMath plans your week around what's on sale, gives you one list, and checks in on Sunday to see what you saved.
Example week. Prices come from your store's sales and change every week.

Why CartMath?
Built for families who already shop the weekly ad.
Real prices
H-E-B's weekly ad, entered by hand each week, and Kroger prices live from Kroger's official API.
Fits your family
Portions for your kids' ages, and dinners that skip your allergies and the tools you don't have.
No receipts, no spreadsheets
No scanning and no logging every purchase. One question on Sunday.
Sunday check-in
See what you saved, in one tap.
On Sunday, CartMath asks about how much you spent on groceries. The gap between that and your usual week is your savings, week after week.
Questions
When can I start using CartMath?
CartMath is in a small pilot with families in Fort Worth right now. Join the waitlist and we'll email you when it opens at your store.
Which stores does it work with?
H-E-B and Kroger stores in Texas. We're starting in Fort Worth and adding stores as families join.
Where do the prices come from?
At H-E-B, from each week's ad and our own price checks. At Kroger, from Kroger's official product API, fresh each time you open your plan. Either way, they're estimates of what you'll pay in the store.
How do you count my savings?
Every Sunday, CartMath asks about how much you spent on groceries. Your savings are the difference from the usual week you told us about. We never count savings you didn't report.
Will it cost anything?
It's free during the pilot. When CartMath launches in the App Store and Google Play, it will have a free trial and then a subscription. You'll see the price before you start.
Is CartMath part of H-E-B or Kroger?
No. CartMath is independent and not affiliated with H-E-B or Kroger.
What do you do with my email?
We use it only to tell you when CartMath opens near you. To be taken off the list, email hello@cartmath.app. More in our Privacy Policy.
