Affirm gives you a clearer way to spread out the cost of a purchase. Instead of putting everything on a credit card and figuring out the interest later, you choose a payment plan before completing the order and see the total cost upfront.

The app is useful for more than making a new purchase. It also keeps your active plans, payment dates, remaining balances, and recent activity together, so you always know what is due next.

How to install Affirm

1. Open the Affirm page on your iPhone.

2. Tap Get.

3. Confirm the installation with Face ID or your Apple ID password.

4. Open the app and create an account or sign in.

5. Complete the requested identity check.

You can explore stores and current offers before buying anything. Approval is handled separately for each purchase.

Choose a payment plan that fits

Affirm works online, in stores, and inside the app. When a purchase qualifies, you may see several ways to pay: four interest-free payments every two weeks, shorter monthly plans, or longer financing.

The available options depend on the purchase and your approval. Some plans have 0% APR, while others charge interest. Before you accept, Affirm shows the payment dates, the amount of each installment, and the full cost.

That transparency is the main reason many people prefer Affirm. There are no surprise late fees, although missed payments can still affect your ability to use the service in the future.

Shop through the app

Affirm includes a shopping section where you can browse products and stores, check current offers, and see an estimate of your purchasing power.

You are not limited to retailers that show an Affirm button at checkout. For supported purchases, the app can create a one-time virtual card that works like a regular card number. It must be used within a limited time and only for the approved amount.

The app also supports Apple Pay for qualifying purchases, making Affirm easier to use when shopping from an iPhone or at participating stores.

Keep every payment organized

Once you have an active plan, the schedule is easy to follow. The app shows upcoming installments, completed payments, and how much remains.

You can turn on AutoPay, make a payment early, or pay off the balance before the final date. Notifications help you remember upcoming charges without checking the app every day.

This is particularly helpful when you have more than one purchase open. Instead of tracking several emails and store receipts, you can see the full picture in one place.

Affirm Card

The Affirm Card is a flexible Visa debit card for eligible customers in the United States. It can be used to pay in full for everyday purchases or to request a payment plan for an eligible purchase.

You can manage the card from the app, review activity, and choose to pay over time before or shortly after a transaction when that option is available.

The card has no annual fee, but approval and payment terms still depend on the purchase.

Is Affirm free?

Affirm is free to download and does not charge a subscription fee for its standard payment service.

Pay in 4 plans are generally interest-free. Longer plans may have an APR from 0% to 36%, depending on the offer and your eligibility. Always check the total cost before confirming.

Frequently asked questions

Can I use Affirm at any store?

Affirm works directly with many retailers. A virtual card or Affirm Card may also be available for purchases at other stores that accept Visa.

Does applying affect my credit score?

Checking available plans usually does not affect your credit score. Some financing activity may still be reported to credit bureaus, depending on the plan.

Can I pay early?

Yes. You can make an early payment or pay off an active plan from the app without a prepayment penalty.

Does Affirm charge late fees?

Affirm does not charge late fees. Missing a payment may still affect future approval and could have other consequences.

Is every purchase approved?

No. Affirm reviews each request separately, and the terms available for one purchase may be different from the next.

Get Affirm on your iPhone

Affirm is most useful when you already know how a purchase fits into your budget and simply want more time to pay for it. The app makes the costs easy to understand and keeps every installment visible from the start.

It is not extra money, but it can be a practical way to handle a planned purchase without losing track of the final price.
