Where Hetk wins

Price

Hetk’s Professional plan ($50/year) costs less than half of OneCal’s cheapest annual plan ($60/year for 2 calendars). For 5 calendars, OneCal charges $120/year, while Hetk charges $50/year for unlimited calendars with up to 8 sync pairs.

Longer free trial

Hetk offers a 21-day trial vs OneCal’s 14 days.

Apple iCloud support

Both support iCloud, but Hetk includes it at the same price point, no add-on or higher tier required.

Where OneCal wins

OneCal includes Calendly-style booking links. Hetk focuses purely on calendar sync, if you need scheduling links, you’d use a separate tool.

Unified calendar view

OneCal offers a combined calendar interface where you can view and manage all your calendars in one place. Hetk syncs events between calendars but doesn’t provide a separate calendar UI.

Mobile apps

OneCal has native iOS and Android apps. Hetk is a web application.

Detailed pricing breakdown

  • Scale: ~$300/year for 10+ calendars
  • Cost per calendar: $30–60/year depending on tier

The pricing gap is dramatic. If you manage 5 calendars, Hetk charges $50/year (Professional) while OneCal charges $120/year, that’s 58% cheaper with Hetk, and Hetk’s plan supports 8 calendars, not 5.

Feature-by-feature analysis

Both Hetk and OneCal handle the core task of real-time calendar synchronization across Google, Outlook, and iCloud. Where they diverge is in scope and cost efficiency.

OneCal wraps calendar sync into a broader platform that includes scheduling links and a unified calendar UI. If you want to manage multiple calendars from one interface and share booking availability, OneCal’s bundled approach makes sense. However, this bundling adds cost, you’re paying for features you may not need.

Hetk takes the opposite approach: it does one thing exceptionally well and keeps the price low. If you already manage your calendars in Google Calendar, Outlook, or iCloud and just want them synchronized, Hetk handles that at a fraction of OneCal’s cost. The privacy controls (Mark as Private, Show As, Identity Transform) are built in at every tier, giving you fine-grained control over what gets synced and how events appear across providers.

The real-time sync quality is equivalent on both platforms, both use webhooks to detect and propagate changes within seconds. OneCal’s advantage is the extra features; Hetk’s advantage is simplicity and price.

Switching to Hetk

If you’re already using OneCal and want to switch:

  1. Sign up for Hetk and complete the 21-day free trial
  2. Connect your calendar accounts, Google, Outlook, and/or iCloud (same accounts as OneCal)
  3. Create sync relationships matching your OneCal setup (Hetk’s UI mirrors the same workflow)
  4. Disable OneCal syncs once you’ve verified Hetk is working correctly
  5. No data loss, events remain in your calendar accounts; you’re just changing what syncs them

Hetk syncs directly to your calendar providers, so there’s no migration or data export needed. Your events stay where they are; Hetk just takes over the synchronization job.

FAQ

Does Hetk have scheduling links like OneCal?

No, Hetk focuses purely on calendar sync. If you need booking links, pair Hetk with Calendly or a similar tool, the combined cost will still be less than OneCal alone.

Can I use both Hetk and OneCal together?

You can technically, but it’s not recommended. Running two sync services on the same calendars risks duplicate events and conflicts. Pick one per sync relationship.

Does OneCal offer better privacy controls?

Both platforms offer privacy controls, but Hetk’s are more granular and included at every tier. OneCal requires higher-tier plans for some features. Hetk gives you Mark as Private, Show As, and Identity Transform out of the box.

What if I only need to sync 2 calendars?

Hetk Personal ($15/year for 3 calendars) is one-quarter the price of OneCal’s 2-calendar plan ($60/year). You’re paying for potential extra calendars, but at such a low price point, the flexibility is worth it.

How do sync limits work on each platform?

Hetk supports unlimited calendars on both plans. The limit is on sync pairs: Personal supports up to 3 sync pairs, Professional supports up to 8. You can connect as many calendars as you need between those sync pair limits. OneCal limits both calendars and sync relationships based on plan tier.
