About CartSmart
Grocery math without the friction.
CartSmart is a free grocery calculator that helps you track your running total, stay inside your budget, and compare brands by unit price while you shop. It is designed to work fast on your phone so you can use it one-handed in the aisle.
Is it free?
Yes, always free. We make money from ads, not you.
Does it save my data?
Your cart saves locally on your device so a refresh does not wipe your work. We do not collect personal data to power the tool.
