OneCal Alternative: How to Switch to Hetk (2026)

Why people look for OneCal alternatives

OneCal bundles calendar sync with booking links, a unified calendar and mobile apps, and tiers its plans by calendar count. If you only want your calendars kept in step, you may not need the rest.

This page is about switching: what carries over, what does not, and the steps. For features side by side, see Hetk vs OneCal. For cost, see the OneCal pricing breakdown.

What Hetk offers instead

Hetk does the sync part: one-way or two-way sync across Google Calendar, Microsoft Outlook, and Apple iCloud, with privacy controls on both plans. It has no booking links, no calendar view of its own and no mobile app.

Who should choose Hetk

Choose Hetk if:

Your main need is keeping calendars in sync across providers
You want strong privacy controls for sensitive events
You connect 3 or more calendars and do not want a cap on them
You prefer a simple, focused tool over an all-in-one platform

Stay with OneCal if:

You need scheduling/booking links
You need a unified calendar view to manage events from one interface
You prefer native mobile apps

OneCal pricing, plan limits, apps and trial checked 2 October 2026 on OneCal's pricing page. Plans may have changed since.

What you keep when switching

Two-way and one-way sync
Privacy controls (Replace the details with “Busy”, Flag the copy as private, title templates)
Multi-provider support (Google, Outlook, iCloud)
Unlimited calendars, limited sync pairs (plan-dependent)

What you’re giving up (and why it matters)

Scheduling/booking pages: OneCal includes Calendly-style links. If you use them, you would need a separate scheduling tool. Calendly Standard is $120/year, so Hetk Professional plus Calendly comes to more than OneCal Essential ($120/year) and less than OneCal Premium ($300/year). If you use booking pages, staying on OneCal may be the cheaper choice.

Unified calendar view: OneCal lets you view all calendars in one interface. Hetk syncs events but doesn’t provide a separate UI. Keep using Google Calendar, Outlook, or your preferred calendar app, Hetk just keeps them in sync.

Mobile apps: OneCal has apps for iOS and Android. Hetk is web-only. Web apps work fine on mobile, but if you need a native app, this is a gap.

Step-by-step: switch from OneCal to Hetk

Visit Hetk and start the free trial: No credit card required, 21 days of full access
Connect your calendar accounts: Google, Outlook, iCloud (same ones you use with OneCal)
Recreate your sync relationships: This mirrors your OneCal setup. Usually 5 minutes for 2-3 syncs
Test for a week: Create a test event and verify it syncs across all providers
Verify privacy settings: Check that your privacy rules (Replace the details with “Busy”, Flag the copy as private, title templates) are working as expected
Disable OneCal: Once confident, disable OneCal’s syncs. Your events stay in place; only the sync service changes
Pick a plan before day 21: Personal is $15/year for 3 sync pairs, Professional $50/year for 8. There’s no free tier, and syncs pause when the trial ends

FAQ

Can I migrate from OneCal to Hetk?

Yes. Simply connect the same Google, Outlook, and iCloud accounts to Hetk, set up your sync relationships, and you’re done. No data export or migration needed, Hetk syncs directly to your calendar accounts.

Will I lose any data when switching?

No. Your calendar events live in Google Calendar, Outlook, and iCloud. OneCal was just syncing between them. When you switch to Hetk, the events stay exactly where they are, you’re just changing the sync service.

Will I lose any features when switching to Hetk?

You’ll lose booking links (use Calendly for that) and the unified calendar view. You keep everything else: sync, privacy controls, multi-provider support, and bi-directional sync.

How many calendars can I sync?

Hetk supports unlimited calendars on both plans. Personal plan supports up to 3 sync pairs; Professional supports up to 8 sync pairs. OneCal’s plans are tiered by calendar count (2, 5, then 50), so the gap widens each time another calendar pushes you into a higher tier.

Is Hetk’s sync as fast as OneCal?

Changes in Google Calendar and Outlook usually arrive within seconds, through push notifications. A safety check runs every 15 minutes in case a notification is missed. Apple iCloud has no push. Hetk checks iCloud every 5 minutes, and less often for a calendar that has been quiet. We have not timed Hetk against OneCal side by side. The 21-day trial lets you check on your own calendars.

What if I’m using OneCal’s scheduling pages?

Hetk has no booking links. You would pair Hetk with a separate scheduling tool, and the two together can cost more than OneCal alone. Check the OneCal pricing breakdown before you switch.

What happens after the 21-day trial?

You pick a plan: Personal at $15/year for 3 sync pairs, or Professional at $50/year for 8. Both connect unlimited calendars. There’s no free tier — if you don’t subscribe, your syncs pause and the events already copied into your calendars stay put as ordinary events. Nothing is deleted, and subscribing later resumes the syncs.

Can I use both OneCal and Hetk at the same time?

Not recommended. Running two sync services on the same calendars creates duplicate events and conflicts. Switch completely to one or the other, or use them for different sync relationships.
