I built a calendar sync tool because I was tired of manually copying events between Google and Outlook
Hey IH 👋
I just launched Hetk — a service that syncs your events across Google Calendar, Microsoft Outlook, and Apple iCloud in real time.
The problem
If you use more than one calendar platform (work Outlook + personal Google, for example), you know the pain. You either manually copy events, set up fragile Zapier automations that lose half the event data, or accept that you'll occasionally double-book yourself.
I hit this myself and looked at existing solutions. Most are either Google-only, charge a monthly fee, or don't support bidirectional sync properly. None of them had the privacy controls I wanted — I don't need my coworkers seeing "Dentist appointment" on my work calendar.
What Hetk does
- Bidirectional sync between Google Calendar, Outlook, and iCloud (any combination)
- One-way sync if you want to mirror events in one direction
- Privacy controls — mark synced events as "Busy" and strip titles, descriptions, and attendees
- Real-time — uses webhooks, not polling, so changes show up in seconds
- 21-day free trial
Pricing
I went with annual pricing to keep it simple and cheap:
- Personal: $10/year (early adopter), $15/year regular
- Professional: $35/year (early adopter), $50/year regular
Annual billing only — no monthly subscriptions to worry about.
What's next
I'm looking for early users who deal with multi-calendar chaos daily. If that's you, I'd love to hear what your setup looks like and what matters most to you.
Check it out at hetk.io.
Happy to answer any questions about the product or the build.
This is a solid build-in-public update because the real product is not just “calendar sync.” It is trust in the sync layer. If someone connects Google, Outlook, and iCloud, they are trusting Hetk not to create duplicates, leak private details, miss events, or quietly break in the background.
That makes the stability work more important than visible feature shipping. Loop breaking, provider-specific failure handling, privacy controls, and cross-provider test coverage are exactly the things that turn a small utility into something people can rely on daily.
One thing I would pressure-test early is the brand frame. Hetk is short, but the product is already bigger than a simple calendar tool. It is becoming more like a personal scheduling infrastructure layer across work and personal systems.
Xevoa .com would fit that direction well because it feels more like a modern workflow/productivity platform, while still leaving room for calendar sync, privacy rules, filtering, event rewriting, and broader cross-app coordination later.
