Most planners are built for a different body.

You have probably tried them. The ones that ask you to rate your productivity. To tick off your morning routine. To plan your week as though energy is something you simply choose to spend.

They do not account for the 48-hour echo. The crash that arrives on Thursday from what you did on Tuesday. The day that felt fine until it did not.

aevum is built on different assumptions. Your system is not broken. It operates on different physics. The goal is not to do more. It is to understand the system you have - and stop being ambushed by it.

Long enough to see the echo Long enough to find the trigger. Long enough to know whether pacing is working.
