You sure can!
If you would like Digit to save a higher percentage for you, you can message "Save More" to Digit to increase the threshold of what Digit is saving for you.
If you've increased Digit's savings by texting "Save More", you can lower it back down by texting "Save Less".
You can message "Minimum" to Digit to set a threshold for which Digit will not attempt to save if your checking balance falls under that amount. Please note, bank transfers take 1 business day to process, so please give yourself a little buffer room.
You can also text "Pause" to put all of Digit's savings on hold for a little while if you need to.
