Should have ability for an approver in a workflow to Approve or Reject or Question from a simple Mobile reply. maybe They can use OOO or Vacation setting to trip a flag that routes to a mobile text flow vs the desktop. that then allows that they stay in the workflow but lighter way to review and act.

Hi, Brad. We currently have a mobile app for iOS users that allows approvers to do these things. We are in the process of completely revamping this app and making an Android version as well.
You can download the current version of the app here: https://itunes.apple.com/us/app/accrualify-inc/id1217761308?mt=8
