A native Mac calendar, built by one person.

Hi 👋, you're about to trust an app with something important: your day. So here's the short version of who I am and why I built this.

Where I'm coming from

For the last 16+ years I've worked in marketing, split between big tech and gaming names (Samsung, TikTok, Ubisoft) and smaller places like SaaS startups and ad agencies. Roles changed, companies changed, tools changed.

Two things never did: email and calendar. Any meaningful work in the 21st century runs on those two rails.

For email, I eventually found Mimestream, a native macOS Gmail client. It's excellent, full recommendation.

For calendar, I never landed. Functionality was missing, or the app was slow, or the design clashed with how I think about time. I kept switching, kept paying, kept being mildly annoyed.

The pivot

Two years ago I decided to come back to something that had always pulled at me but which I'd never committed to: programming.

I started small — little fixes in web dev projects. Then I fell into the Python rabbit hole. Then one evening I looked at my Mac and thought: I'm a macOS user. Let me try Swift. Let me build something real.

I didn't have the idea yet. Then it arrived.

The idea

Build the calendar I'd been looking for. One that actually uses what macOS and Google Calendar can do:

• Real Google Meet integration
• Color-coded events the way Google intended
• Native macOS notifications
• A menu-bar widget that pulls its weight, showing the next meeting, not just the time
• And above all, a native app, not a web page pretending to be one

That's hora Calendar.

Where I am today

16,000+ lines of Swift. A Linear backlog that keeps expanding. One developer, me, shipping from Poland, in public.

If you live in Google Calendar, you use a Mac, and every existing option has let you down in some small way, give hora a shot.

Thanks for reading,
