A native Mac calendar, made by two people in Poland.

hora is a calendar for people who live in Google Calendar and work on a Mac. It's a real Mac app, not a browser tab, and it talks straight to Google. We're Anna and Maciej Szamowscy, the two co-founders. We build hora independently, from Poland.

Why hora exists

For years my work ran on two things: email and calendar. For email I found Mimestream, a native Mac app for Gmail, and stopped looking. For calendar I never landed. Something was always missing, or slow, or just didn't fit how I think about time. A few years ago I went back to programming, looked at my Mac one evening and thought: let me try Swift and build something real. The idea came soon after: build the calendar I'd been looking for.

What started as a side project became a product the two of us run together.

Who we are

Maciej Szamowski, co-founder, development. Maciej builds the app. He spent 16+ years in marketing at companies like Samsung, TikTok and Ubisoft, then went back to programming and taught himself Swift to make hora. szamowski.dev · @szamski

Anna Szamowska, co-founder, publishing, marketing & community. Anna looks after everything between the app and the people who use it. Before hora she worked in the game industry at Ubisoft and Techland. LinkedIn

Before I post anything about hora, I ask myself why it should matter to anyone. I respect communities that protect their space from turning into billboards, and the only feedback that really counts comes from our users.

— Anna

Our jobs overlap a lot, and we both read every review.

What we believe a calendar should be

A real Mac app. Native, fast, with keyboard shortcuts, menu bar, widgets and system notifications.
Straight to Google. hora connects directly to the official Google Calendar API. Your calendars, colours, Meet links, Tasks and rooms stay where they already are.
Your calendar stays with you. Your events are stored on your Mac, and your sign-in tokens stay in the macOS Keychain. Your calendar data never passes through a hora sync server. Our Trust Center explains exactly what our servers can and can't see.
Small and honest. We'd rather do fewer things well than chase every feature.

Where hora is today

hora launched on the Mac App Store on 30 June 2026. You can also get it directly from horacal.app or through Setapp. Since launch, about 1,850 people have opened hora, and 1,500+ Setapp members use it. iPhone and iPad are next: the iOS app is coming on 23 October 2026.
