The app currently (6.7) does not display a goal's daily rate anywhere. The Android app does.

As is, the app currently only presents, in textual form, the amount due in terms of units for on the gallery and on the goal screen for those goals in the red, due 'today'.
Providing the rate can give the user a chance to estimate how much work is about to become due.

Thus one might be able to take a reasonable guess at the amount due to accumulate a particular number of safe days by targeting the daily rate times the number of safe days one wants.

(note: daily rate may change, daily even, for factors such as autodialing)
