Digit provides a feature called Overdraft Prevention as a way to help keep your checking account at a comfortable level. When you enable Overdraft Prevention, Digit will queue up a transfer from your Rainy Day Fund to help bring your checking balance back to the level you set if your checking balance dips below the amount you specified.
For example, if you set this feature at $500, and this morning Digit noticed your checking balance was $480, a $20 transfer from Digit would be automatically created to head back to your checking account to bring your checking balance back to $500.
If you would instead like to set an amount in checking that Digit stops saving at, you can enable the Minimum feature here.
To set this feature up:
1) Open the app and tap into "Overdraft Prevention" below your checking balance.
2) Flip the setting to "On," and specify the amount you want funds sent back to checking at.
Depending on if your bank supports Instant Withdrawals, these transfers are instant by default at no extra charge. Otherwise, the funds will arrive within one business day.
To turn off or adjust the amount of Overdraft Prevention, just click into that section from within the app to access those settings again.
