All of your accounts, composed into one view.

Native calendar for macOS
Every calendar.
One clear course.
Helm brings your Google calendars together in a focused Today view and a calm Monday–Friday week—without turning your schedule into another noisy dashboard.
No hosted backend, analytics, advertising, AI integration, or Gmail access.

Designed for the day ahead
Your schedule, without the static.
Helm keeps the parts of a calendar you use all day close at hand, while leaving advanced controls in Google Calendar when you need them.
A Today view built for momentum.
See what is happening now, what comes next, and the meeting link you need—without hunting through a full month grid.
Edit without breaking stride.
Create, update, move, and delete events from Helm, with conflict protection against newer Google Calendar edits.
Reminders that know when to step forward.
Get a normal notification before a meeting and an optional, prominent interruption shortly before it starts. Helm automatically excludes all-day events, holidays, birthdays, declined invitations, and events marked free.
Privacy by architecture
Your calendar does not become our business.
Helm connects directly from your Mac to Google. There is no Helm cloud service sitting in the middle, and no behavioral analytics watching how you use the app.

Helm is a focused, private calendar built for people whose time is spread across more than one Google account.
