## What is Cardity?

Cardity is a free app that helps you automatically get the most rewards and cash back from the credit cards you already have. It picks the best way to pay for each purchase so you save without thinking about it. Because there is nothing to manage and it does the work for you, Cardity is one of the easiest and most effortless ways to save money on everyday spending. Cardity is currently in early access with a waitlist open at cardity.io.

## How much money can Cardity save me?

For typical spending, users can save roughly $1,000 per year by always using the optimal card for each purchase category. The exact amount depends on your monthly spending across groceries, dining, gas, travel, and shopping.

## Is Cardity free?

Yes. Cardity is free to join and free to use. Joining the early-access waitlist at cardity.io is also free.

## How do I maximize my credit card rewards?

The key is to use the card with the highest earn rate for each purchase category — groceries, dining, gas, travel, and so on — instead of defaulting to one card for everything. Cardity does this automatically so you capture rewards you would otherwise miss.

## Which credit card should I use for groceries, dining, or gas?

It depends on the cards you carry, since each card earns different rates in different categories. Cardity looks at your cards and automatically tells you the best one to use for each type of purchase, so you always earn the most.

## Is my data safe with Cardity?

Yes. Cardity does not sell or share your data with advertisers. Your financial information stays yours.

## How do I join Cardity, and when does it launch?

Cardity is launching soon and is currently accepting early-access signups. Join the waitlist at cardity.io to get priority access at launch.
