Three energy categories Every task belongs to an energy category — Exertion, Recovery, or Administrative. Derupt tracks your daily energy balance so you don't burn out on one type of work. Smart recommendations The recommendation engine suggests what to work on next based on your priorities, due dates, energy balance, and current context. It adapts to where you are and what you need.

Templates for recurring tasks Set up templates with recurrence rules for habits and routines. Derupt generates tasks automatically so nothing falls through the cracks. Voice capture with Siri Use the Action Button or Siri Shortcuts to capture by voice — zero taps, transcribed automatically. Private by design All data stays on your device.
