Saving and Round-Up Apps
These apps don't ask you to plan a budget, they just make saving happen in the background, rounding up everyday card purchases to the nearest dollar or skimming a slice off each paycheck before you can spend it. Some sort the spare change into labeled goals for a trip or an emergency fund, others fold it straight into investments.

The app that made round-up investing a household idea, rounding linked card purchases up to the nearest dollar and putting the spare change into a diversified portfolio rather than a plain savings account. Three tiers run $3, $6, or $12 a month, and the family tier adds a custodial account for kids.

A fee-free online bank account built around two automatic saving habits, rounding debit and credit purchases up to the nearest dollar and skimming a chosen percentage off every paycheck the moment it lands. The savings balance earns a notably higher APY than a typical brick-and-mortar bank.

A goals-based savings app where you write your own round-up and spending rules instead of accepting one fixed formula. Plans run $3, $6, or $12 a month after a 30-day free trial, and each goal gets its own labeled savings pot.

Formerly known as Digit, this app skips round-ups for a different trick, an algorithm that studies your income and spending pattern and quietly tucks away small amounts it judges you can spare. A 30-day free trial leads into a flat monthly fee, with a discount for paying annually.

A free checking and savings account from SoFi where round-up savings land in named Vaults instead of one shared pool, each one earmarked for a specific goal. An automatic save-on-payday option runs alongside it, and the savings side pays a competitive APY.
- 6
A round-up investing app that pays you back in stock rather than cash for some of your everyday purchases, on top of the usual spare-change investing. The Stash Plan runs $12 a month, and an acquisition by Grab announced in February 2026 was still pending at the time of writing.

A free online bank account with no monthly fee and no minimum balance, built around two automatic transfers, Save Your Change rounds up debit purchases and Save Your Pay skims a percentage off each direct deposit. Savings transfers are unlimited.
