Your to-do list keeps growing. The energy you have in a day does not. enough plans your day by energy instead of hours. Rather than slicing the day into 30-minute blocks, you decide how much you can carry today, then plan only within that. ■ Plan with an Energy Budget Set today's Energy Budget when you start — Light, Steady, or Full, whatever matches how you actually feel. Give each Action an energy value and watch what's left. Once the budget is spent, nothing more fits, so overcommitting gets harder. ■ Backlog and Focus Dump everything into Backlog. Sorting it out can wait. Move only today's work into Focus, and that's your list. When the day goes sideways, plan again. ■ Wrap the day Finish every Action in Focus and you can close the day. Things left in Backlog are fine. Some days, what you did is enough. ■ A reset time that fits you Your budget resets at the hour you choose, because a day that ends at 2am isn't the same as one that ends at 10pm. While travelling, the reset follows your device's local time. ■ Also included · Save frequent Actions as shortcuts · Due dates and times · Sort by date created, energy, or due date · Multi-select to move items in one go · Log how it felt — easier, about right, or harder · See your weekly energy trend · Sign in with Apple to sync across devices · Start straight away without an account · Works offline · English and Korean Do less. Finish more.
