Oportun

Oportun (formerly known as Digit) analyzes your daily spending patterns and account balances to identify money you can afford to move to savings without impacting your ability to cover bills or immediate expenses. The app calculates what you can realistically spare each day, sometimes just a few cents, and transfers those amounts into a separate savings account. This low-friction approach removes the decision-making burden that stops many young adults from saving.

Particularly effective for students and young adults living paycheck-to-paycheck who find manual budgeting overwhelming or who want savings to happen in the background. The algorithm learns your unique financial rhythm rather than applying one-size-fits-all rules, making it gentler on irregular income than fixed savings targets. Works well as the automatic "capture the leftovers" layer of a broader budgeting strategy.
