Your mornings, back.

Halcyon is a calendar that keeps your best hours free. It books meetings around your focus, not into it.

Act IWhy

The problem

Calendars fill up from the top.

Every invite lands in the first free slot, and the first free slot is usually the hour you meant to think in. Halcyon moves the line.

Act IIFeatures

What it does

Three rules, kept for you.

Focus first

Your deep-work blocks go in before anyone else's meetings, every week.

Smart batching

Calls are grouped into afternoons, so the day isn't cut into twenty-minute scraps.

Polite no

Halcyon suggests a better slot instead of declining, and the other side picks with one tap.

Act IIIThe star

The app

Pick a slot, keep the morning.

When someone asks for your time, Halcyon offers the hours that cost you least. You approve, it books.

Act VIIProgramme notes

Questions

Does it replace my calendar?

No. Halcyon sits on top of Google Calendar or Outlook and only decides where new things go.

What do the people I meet see?

A short list of times that work for both of you. No new app to install.

Can I override it?

Always. Drag anything anywhere; Halcyon learns from what you move.
