A personal energy planner, built for one person.
regen helps its author plan a day around the energy it will actually cost, using the ideas behind spoon theory. It reads her own calendar and her own task list, works out what a day is likely to demand, and helps her arrange it so the week stays survivable.
It is a private, single-user application. There is no sign-up, no public instance, and nothing here to log in to. This page exists because Google asks every application requesting calendar access to publish a home page and a privacy policy, which is a reasonable thing to ask.
