Hetk vs SyncGene: Calendar Sync Compared (2026)

SyncGene and Hetk both sync calendars across Google, Outlook, and iCloud. But they take different approaches to pricing, sync speed, and privacy — and those differences matter depending on your workflow.

This guide compares both tools side by side so you can pick the right one.

Quick comparison

Sync speed

This is the biggest technical difference.

Hetk uses webhooks — when you create or edit an event in Google Calendar, Google notifies Hetk immediately, and the change appears in Outlook within seconds. Microsoft Graph also pushes changes via webhooks. iCloud uses polling every 3–5 minutes (Apple doesn’t support webhooks for CalDAV).

SyncGene uses periodic polling. It checks your calendars on a schedule and syncs any changes it finds. This means changes can take minutes to appear in the other calendar. For most people this is fine, but if you’re in back-to-back meetings and need changes to appear immediately, the delay can cause double-bookings.

Bottom line: If real-time sync matters to you, Hetk is faster. If you’re okay with a few minutes of delay, both work.

Privacy controls

This is where the two tools diverge significantly.

Hetk lets you control what gets synced:

• Mark as Private: Synced events appear as “Busy” blocks with the title, description, location, and attendees stripped. Your coworkers see that you’re busy, but not why.
• Show As: Choose whether synced events show as Busy, Free, Tentative, or keep the original status.
• Identity Transform: Synced events show your email as the organizer instead of the original sender. Useful when syncing client calendars to your work calendar.
• Confidential visibility: Events marked as confidential in Outlook keep their sensitivity level when synced to Google (and vice versa).

SyncGene syncs events as-is. There’s no option to strip content, mark events as private, or control visibility. Every event is copied exactly, including titles, descriptions, and attendee lists.

Bottom line: If you sync personal events to a work calendar (or the reverse), Hetk’s privacy controls prevent your employer from seeing “Dentist appointment at 2pm” or your client list. SyncGene doesn’t offer this.

Pricing

Hetk has two plans:

• Personal ($15/year or $2/month): Up to 3 calendar sources, unlimited sync relationships, bi-directional sync, privacy controls. Early adopter pricing: $10/year or $1/month.
• Professional ($50/year or $6/month): Up to 8 calendar sources, everything in Personal plus priority support. Early adopter pricing: $35/year or $3/month.

Both include a 21-day free trial with full feature access. No credit card required.

SyncGene has three tiers:

• Free: Limited sync with restrictions on number of sources and sync frequency.
• Premium (~$70/year): Unlimited sources, automatic sync, folder mapping, calendar sharing.
• Team (varies): Up to 4 members with shared billing.
• Enterprise (custom): 5–100 members, dedicated account manager.

Bottom line: Hetk is cheaper for individual use ($15/yr vs ~$70/yr). SyncGene’s free tier is useful for testing, but the limitations push most users to Premium. Hetk’s 21-day trial gives you full access without restrictions.

Setup and usability

Hetk setup takes about 2 minutes:

1. Sign in with Google or Microsoft
2. Connect your other calendar provider(s)
3. Select which calendars to sync
4. Choose sync direction and privacy settings
5. Sync starts automatically

No admin approval required for personal accounts. The web interface focuses on sync — there’s no clutter from contact or task features.

SyncGene setup is similar but slightly more complex because it handles contacts, calendars, and tasks in one dashboard. You need to:

1. Create a SyncGene account
2. Add your calendar sources
3. Configure folder mapping (which calendar syncs to which)
4. Set sync direction
5. Start sync

The dashboard can feel overwhelming if you only want calendar sync, since SyncGene is designed as a broader synchronization platform.

Bottom line: Both are straightforward. Hetk is simpler if you only need calendar sync. SyncGene is more capable if you also want to sync contacts and tasks.

What SyncGene does that Hetk doesn’t

• Contact sync: Sync contacts across Google, iCloud, Outlook, and Exchange. If you need contacts and calendars synced together, SyncGene handles both.
• Task sync: Sync tasks and reminders between platforms.
• Exchange support: Direct Exchange server connectivity (not just Outlook/Microsoft 365).
• Free tier: A limited free plan for basic sync needs.
• Mobile app: Dedicated iOS and Android apps.

What Hetk does that SyncGene doesn’t

• Real-time sync: Webhook-based instant sync vs. polling.
• Privacy controls: Mark private, show as busy, strip content, identity transform.
• Duplicate detection: Automatically prevents the same event from being synced twice.
• Confidential visibility preservation: Outlook’s “confidential” sensitivity maps correctly to Google’s “private” visibility and back.
• Source-wins conflict resolution: If a synced event is deleted on the target calendar, Hetk restores it from the source — preventing accidental data loss.

SyncGene is merging with CiraHub

One important thing to know: SyncGene is being merged into CiraHub, a more enterprise-focused product from the same company. This means SyncGene as a standalone product may change significantly — features could move, pricing could shift, or the product could eventually be retired in favor of CiraHub.

If you’re choosing a sync tool for the long term, this is worth considering. Hetk is an independent product with no planned mergers or acquisitions.

Which one should you choose?

Choose Hetk if:

• You want the cheapest option for calendar sync ($15/year vs ~$70/year)
• Real-time sync matters (seconds, not minutes)
• You need privacy controls (syncing personal ↔ work calendars)
• You only need calendar sync, not contacts or tasks
• You prefer a focused, simple interface

Choose SyncGene if:

• You need to sync contacts and tasks alongside calendars
• You need direct Exchange server support
• You want a free tier for basic sync
• You’re already using CiraHub or plan to migrate to it
