Buy now, pay later apps have become increasingly popular to help consumers pay off purchases over a longer period of time. Their ease of use, low fees and often interest-free payments have made them attractive options for shopping both online and in-person. And in an era when many people are living paycheck to paycheck, these apps help people to make purchases they otherwise couldn't afford.

Buy now, pay later apps are useful tools, but they aren't all created equally. Below we've rounded up our six favorite apps to help you choose the right one for you.

Affirm doesn't charge any fees, including late fees, prepayment fees or annual fees. You might pay interest depending on the size of your purchase, where you're shopping and the payment plan you choose. If you do owe interest, you'll know exactly how much upfront.

Pros: 

• You can finance purchases up to$17,500.
• No fees, including late fees, prepayment fees, or other.
  
• You can choose from multiple repayment plans.
  
• Accepted at most major retailers.

Cons:
