OneCal Alternative — Hetk

Looking for a OneCal alternative? Hetk offers the same calendar sync features at 85% lower cost.

Why people look for OneCal alternatives

OneCal is a popular calendar sync tool, but its pricing is steep. For 3 calendars, OneCal charges around $100/year, and adding more calendars increases the cost further. If you need real-time sync without paying premium prices, you start looking for alternatives.

What Hetk offers instead

Hetk delivers the core features people use OneCal for — real-time bi-directional sync across Google Calendar, Microsoft Outlook, and Apple iCloud — at a fraction of the cost. Plus, privacy controls come built-in at all pricing tiers, not as add-ons.

Quick comparison

What OneCal does better

Scheduling links: OneCal includes Calendly-style booking links, letting you share your availability with others. Hetk focuses purely on calendar sync — if you need booking pages, you’d use a dedicated scheduling tool like Calendly.

Unified calendar view: OneCal provides a combined calendar interface where you can view and manage all your calendars in one place. Hetk syncs events between your existing calendars; it doesn’t provide a separate calendar UI.

Native mobile apps: OneCal has iOS and Android apps. Hetk is a web application, accessible from any browser on any device.

What Hetk does better

Price: Hetk’s Professional plan ($50/year for up to 8 calendars) is less than half the cost of OneCal’s basic plan ($60/year for 2 calendars). If you manage 5+ calendars, the savings add up fast.

Privacy controls included: Hetk includes privacy features (Mark as Private, Show As, Identity Transform) at every tier. You don’t need a more expensive plan to protect sensitive event details.

Apple iCloud support: Both support iCloud, but Hetk includes it at the same price point — no higher tier required.

Simpler, focused product: Hetk does one thing well: keep calendars in sync. No scheduling features, no mobile apps, just reliable sync with privacy controls. If that’s all you need, Hetk is faster and cheaper to use.

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 manage 3 or more calendars and want to minimize cost
• You prefer a simple, focused tool over an all-in-one platform

Stay with OneCal if:

• You need scheduling/booking links (use Hetk + Calendly instead)
• You need a unified calendar view to manage events from one interface
• You prefer native mobile apps

Real frustrations with OneCal’s pricing

People switch from OneCal because the costs add up quickly and the feature set doesn’t justify the price:

“I only need sync, but I’m paying for scheduling features I don’t use” — OneCal bundles sync with booking pages and a unified calendar UI. If you only need sync, you’re subsidizing features that don’t benefit you. Hetk unbundles this: sync is just sync, at a fraction of the cost.

“My bill doubled when I added a third calendar” — OneCal’s per-calendar pricing model means each additional calendar adds $20–60/year. Hetk’s plan-based model means unlimited calendars (up to plan limit) with no per-calendar surcharge. Go from 2 to 5 calendars? OneCal charges $60+ more. Hetk stays at $50.

“The mobile apps never sync correctly” — Some users report that OneCal’s mobile apps have sync lag or inconsistencies. Hetk’s web app syncs in real time via webhooks — same speed on desktop or mobile.

“I’m locked into OneCal because switching seems complicated” — It’s not. Your calendar data lives in Google, Outlook, and iCloud. OneCal is just syncing between them. Switching to Hetk takes 5 minutes.

Cost comparison: real scenarios

Freelancer managing 4 calendars (personal, 3 client accounts):

• OneCal: $60/year (base) + $20 × 2 (extra calendars) = $100/year
• Hetk: $50/year (Professional covers 8 calendars)
• Savings: $50/year (50%)

Executive with personal, corporate, and board calendars:

• OneCal: $60 + $20 + $20 = $100/year
• Hetk: $50/year
• Savings: $50/year (50%)

Agency managing 6 shared calendars:

• OneCal: $60 (base) + $20 × 4 (extra) = $140/year
• Hetk: $50/year (Professional)
• Savings: $90/year (64%)

What you keep when switching

• Real-time bi-directional sync
• Privacy controls (Mark as Private, Show As, Identity Transform)
• Multi-provider support (Google, Outlook, iCloud)
• Unlimited sync relationships

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

Scheduling/booking pages — OneCal includes Calendly-style links. If you use them, switch to Calendly standalone ($10/month) and pay $50 (Hetk) + $120 (Calendly) = $170/year. Still cheaper than high-tier OneCal plans. If you don’t use booking pages, you lose nothing important.

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 iOS and Android apps. Hetk is web-only. Web apps work fine on mobile, but if you need a native app, this is a gap. Many users find the web app perfectly adequate.

Step-by-step: switch from OneCal to Hetk

1. Visit Hetk and start the free trial — No credit card required, 21 days of full access
2. Connect your calendar accounts — Google, Outlook, iCloud (same ones you use with OneCal)
3. Recreate your sync relationships — This mirrors your OneCal setup. Usually 5 minutes for 2-3 syncs
4. Test for a week — Create a test event and verify it syncs across all providers
5. Verify privacy settings — Check that your privacy rules (Mark as Private, etc.) are working as expected
6. Disable OneCal — Once confident, disable OneCal’s syncs. Your events stay in place; only the sync service changes
7. Keep the free tier — After trial ends, upgrade to Personal ($15) or Professional ($50), or stay on the free tier (1 sync relationship)

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: real-time sync, privacy controls, multi-provider support, and bi-directional sync.

How many calendars can I sync?

Hetk’s Personal plan supports up to 3 calendars, Professional plan supports up to 8. OneCal charges per calendar above a small limit, so the gap widens as you add more calendars.

Is Hetk’s sync as fast as OneCal?

Hetk uses webhooks for real-time sync — events sync in seconds, just like OneCal. No polling delays, no waiting.

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

If you need booking links, pair Hetk ($50/year) with Calendly ($10/month = $120/year). Total: $170/year for sync + booking. Still cheaper than many OneCal tier upgrades.

What happens after the 21-day trial?

You can stay on Hetk’s free tier (1 sync relationship), or upgrade to Personal ($15/year for 3 calendars) or Professional ($50/year for 8 calendars). No credit card required to start.

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.
