Schema

/ˈskiː·mə/noun
  1. A calendar app of its own, built around how you actually plan.“Bring in your Google calendars, so everything lives in one place.”
  2. The way you color it: by calendar, series, title or your own rules.“Every SL BIOLOGY class, one color.”
  3. The way you group and filter it, with smart groups and saved views.“Show only school.”
  4. Keyboard first. ⌘K finds and does anything; quick add understands plain words.“lunch fri 12pm”

What it does

A calendar that feels like yours.

Schema is built for people with busy weeks: classes, deadlines, side projects. It bends to how you think instead of how a calendar thinks.

🎨

Color everything, your way

Every calendar has a color. Recolor one event, a whole repeating series, every event with the same title, or write a rule: “anything with exam in the name is red.” Colors live in Schema, never in Google.

⌘

Keyboard first

⌘K finds any event, jumps to any date and runs any command. Quick add turns “lunch fri 12pm” into an event.

🗂️

Groups and saved views

Group events across calendars, hide or isolate them, and save a view like “School only” to return to with ⌃1.

🔗

Google Calendar, both ways

See your calendars and edit them. Create, drag, resize, move and delete, with undo, for single events and whole series.

🌙

Wait

A calm full-screen clock for when you step away: what’s on now, how long is left, and the rest of today.

🪪

Nexus: your Schema account

Your profile, your plan, the people you connect with, and your colors, rules, groups and views on every Mac. Your events stay in Google; only you can read what Nexus keeps.

✨

Made to look like the Mac

Glass panels over a color field you choose, light and dark, and an accent color of your own.

Schema Black

BLACK

The extras, in smoked glass. Free stays genuinely useful; Black is for people who live in their calendar.

Questions

Good to know.

Does Schema change my Google calendars?

Only when you edit an event in Schema, and only on calendars you can edit. Colors, groups, views and rules stay in Schema. Guests are never emailed by Schema.

Where is my data kept?

Your events stay in Google. Your Google sign-in is kept in your Mac’s Keychain. If you make a Nexus account, your profile and settings are stored with our database provider and only you can read them. See the privacy policy.

Is Schema free?

Yes. The calendar, colors, keyboard control, Google editing and groups are free. Schema Black adds extras like syncing between Macs and Schedule Builder, and is coming soon.

Which Macs does it run on?

Macs running macOS 26 or later.

Does it work with iCloud or Outlook calendars?

Google Calendar works today. Apple (iCloud) calendars are planned.
