Before you can move money in or out you will need to link starship to your preferred checking account. It's pretty easy to do just follow these instructions:
Tap the Profile icon in upper right corner
Tap "Link Bank"
Follow the prompts to securely link your preferred checking account to starship. You can instantly link your bank account by using your banking credentials, or by your account and routing number. If you are linking using your account and routing number, please check your bank account for micro-deposits. This can take some time before your bank receives these micro-deposits
When received, you will need to come back into the starship app’s Profile section and tap “Verify Bank.”
Once your bank is verified, you’ll be able to make contributions (deposit into starship), reimbursements (pay yourself back), order your card, and set or change your monthly recurring contribution amount.
