The sky — your year as an orbit

Zenith Calendar has one screen, and it is the sky — the whole calendar screen, one canvas that becomes each view. Your year is drawn on it as an orbit round the sun. Each thing you have to do is a body on that orbit. Your calendars are layers you show, hide and reorder.

#The year as an orbit

The sun sits in the middle. Round it runs the year ring, with the solstices and equinoxes as faint spokes. The same canvas turns into the other views — the years, a day, a week and a month. The app opens on the year.

#Commitments as bodies

A commitment — anything on your calendar, an event or a thing to do — is drawn as a body. Its form says how it comes back: a ☄ meteor passes once, a ↻ asteroid keeps coming round, and a ✦ fixed star returns every year.

#Almanacs as layers

Every commitment lives in an almanac — one of your calendars, a named, coloured layer of commitments. An almanac is either one of your own or a mirror of a calendar already on the phone. It is plugged into at most one outside source, or into none. None is an ordinary and complete thing to be.

#Local first

The phone's own calendars are read on the phone, and nothing read from them leaves it. The network is used only for ask the sky and a few services you choose.

#The big date

At the top left stands the picked day, such as "september 18", with "friday · 2026" under it. When more than one almanac can take a new commitment, the name of the one it will land in is added. In another calendar system (Gold), you see that system's date, with the gregorian date small under it. In the years view, it shows the year and "the sun, moving through the years". Tap the big date to go to today.

#The corner buttons

• Bottom left. The microphone, "voice", lets you speak commitments. ✛ "add" makes a new commitment on the picked day. Hold ✛ for "✛ a commitment", "◔ an almanac" or "✎ a journal entry". Three almanacs of your own are free; past three, "◔ an almanac" asks for Gold.
• Bottom right. ‹ "back" shows only away from the year view. ◉ "today" shows only when the picked day is not today or another year is showing. The "almanacs" book opens the almanac chips; hold it for the binder — the page where all your almanacs live. ⚙ "settings" opens settings; hold it for quick settings.
• Top right. ◐ "tomorrow" plans tomorrow. The star, "AI", opens ask the sky — the calendar's built-in AI assistant — and shows only while the assistant is on. The rocket, "shuttle", opens the Shuttle — the suite's shared tray for passing text and files between Zenith apps — with a count of what is riding it.

"button labels" is on by default. It puts a word beside each round button, across the whole app. Turn it off and each button stands alone. You also find it in Settings › ease.

#Quick settings

Hold ⚙ on the sky and a small panel headed "QUICK SETTINGS" opens beside it. Each row shows ◉ when on and ○ when off:

The two offline switches are the same ones as in the binder's settings. Turn "nothing leaves this phone" off again and what was held back is sent, and Drive catches up.

#The notice line

One quiet line of feedback appears at the bottom centre, above everything else on screen. It goes after 4 seconds. Sometimes it carries one tap beside it, such as "undo". When something is refused because its almanac is locked, the line ends "locked — unlock it first" and the refuse sound plays.
