If you want to start saving from a different checking account, then you'll first have to remove the account that Digit is currently linked to. When the account that Digit saves from changes, we need to return your saved balance back to you, both as a legal requirement and to keep our technical info straight by starting from a clean slate.
Below are the steps to change checking accounts through the Digit app - you can also do so at this link: https://digit.co/disconnect-checking-account
1) Tap the icon with your initials in the upper-lefthand corner to access your account settings.
2) Tap "Change" next to your currently linked checking account.
3) If the account you first had connected is still open and able to receive the withdrawal of your balance, click Yes. If that account is currently closed or unable to make and receive transfers, choose No to have a check sent to you for your balance.
Afterwards, you'll receive an email from Digit confirming that your balance is being returned to you via the method you chose. This email will also give details on any saves that were still pending when you changed accounts, letting you know when you should expect to also see those returned.
