Daily Planner App Built for Follow-Through

What makes a daily planner app actually work?

Two things most planners skip: a plan sized to the capacity you actually have today, and something that happens at the start of a block. Arranging tasks is the part you can already do.

A calendar cannot distinguish a 9am hour after eight hours of sleep from a 3pm hour on your fourth short night. From its point of view they are identical containers, which is why a plan built from availability alone keeps overcommitting you.

MaxDex builds a 48-hour energy curve and shapes the day around it, then places a voice check-in at the transition into work.

Why do my daily plans keep failing?

Usually because they are sized to your best day and attempted on an average one. A plan you fail most days raises the aversiveness of everything on it, which makes the next day harder rather than easier.

The second common cause is that hard tasks land in low-capacity windows. Sleep debt and the circadian afternoon dip both raise task aversiveness, so an ambitious 2pm deep-work block is fighting your physiology as well as your motivation.

How does energy-aware planning differ from time-blocking?

Time-blocking asks whether an hour is free. Energy-aware planning asks whether you will be able to do that kind of work in that hour, and places demanding tasks in your genuine peaks.

Chronotype is inferred from the circular mean of your sleep midpoints over two to three weeks, not from a questionnaire you answered once — see the energy model.

• Peaks protected for demanding work rather than leaked to reactive tasks
• Low-capacity windows filled with admin, recovery or movement
• The plan shrinks on a bad day instead of setting you up to fail it
• Your chronotype shifts the curve, so night owls are not told to deep-work at 8am

Does it replace my calendar?

No. It syncs two ways with your device calendar so existing commitments are respected, and it creates its own calendar so MaxDex blocks stay distinguishable from your real events.

It proposes rather than imposes. A planner that rearranges itself without asking is a planner you stop trusting, and trust is the whole reason you would open it in the morning.
