Clockwise Alternative: Hetk for Calendar Sync

Clockwise shut down. Now what?

On March 27, 2026, Clockwise was acquired by Salesforce and shut down with about a week’s notice. Over 40,000 organizations, including Uber, Netflix, and Atlassian, lost their calendar tool overnight. No data export. No transition period.

If you used Clockwise primarily for calendar sync (merging multiple calendars, blocking time across accounts), Hetk is a straightforward replacement.

What Clockwise users actually used

Based on community feedback after the shutdown, most Clockwise users valued:

• Calendar merging: Seeing all calendars in one view and keeping them in sync
• Time blocking: Automatically blocking personal time on work calendars
• Simplicity: Many users found Clockwise’s AI features annoying and just wanted basic sync

As one Hacker News commenter put it: “I only used it for the merging functionality, I didn’t use any of the AI (in fact I found it annoying).”

How Hetk replaces Clockwise

Clockwise shutdown status checked 2 October 2026 on Clockwise's shutdown notice. Plans may have changed since.

What Hetk does

Hetk syncs events between Google Calendar, Microsoft Outlook, and Apple iCloud. When you create an event in one calendar, Hetk copies it to the others; edit or delete the original and its copies follow. 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.

You choose the sync direction (one-way or bi-directional) and privacy settings (replace a copy’s details with “Busy”, flag the copy as private, or both). That’s it. No AI scheduling, no “focus time” automation, no features you didn’t ask for.

What Hetk doesn’t do

Hetk is not a Clockwise replacement if you relied on:

• AI-powered scheduling optimization: Hetk doesn’t rearrange your calendar
• Focus time protection: Hetk doesn’t automatically block deep work time
• Team analytics: Hetk doesn’t track meeting load across teams
• Smart meeting scheduling: Hetk doesn’t suggest optimal meeting times

If you need those features, Reclaim.ai or Morgen are better alternatives. But if you just need reliable calendar sync, the feature most Clockwise users actually used, Hetk does it for a fraction of the cost.

Why not Reclaim.ai?

Reclaim is the most-promoted Clockwise alternative. But consider:

• Reclaim doesn’t support iCloud: If you use Apple devices, you lose a calendar provider
• Reclaim’s paid pricing starts at $10/month per seat billed annually ($120/year), Hetk is $15/year
• Reclaim adds more AI, not less: If you left Clockwise wanting simplicity, Reclaim may repeat the problem

Hetk is self-funded, focused on one thing (calendar sync), and priced to be sustainable without growth-at-all-costs pressure.

Pricing comparison

Hetk Professional costs 48% less than CalendarBridge Premium, 58% less than Reclaim Starter, and 72% less than Morgen Pro, on annual billing.

Reclaim.ai pricing, calendar sync limits and provider support checked 2 October 2026 on Reclaim's pricing page. Plans may have changed since. Morgen pricing and trial checked 2 October 2026 on Morgen's pricing page. Plans may have changed since. CalendarBridge pricing, plan limits and sync claims checked 2 October 2026 on CalendarBridge's pricing page. Plans may have changed since.

Frequently asked questions

Can Hetk replace Clockwise for calendar merging?

Yes, if you used Clockwise to keep multiple calendars in sync. Hetk syncs events between Google Calendar, Microsoft Outlook, and Apple iCloud. When a meeting is added to one calendar, Hetk copies it to the others, usually within seconds for Google and Outlook and within minutes for iCloud. You can sync one-way (source to target only) or bi-directionally (new events flow both ways). Privacy controls let you show full details or just “Busy” blocks, the same time-blocking effect Clockwise provided.

Does Hetk have AI features?

No. Hetk is a focused calendar sync tool with no AI scheduling, no automatic rearranging of your calendar, and no “smart” features that make changes you didn’t ask for. Many Clockwise users reported finding the AI features more annoying than helpful. Hetk takes the opposite approach: you set up your sync rules, and it follows them exactly.

Is Hetk going to shut down like Clockwise?

Hetk is built by a solo founder in Estonia, self-funded with no venture capital. There’s no acquisition risk and no pressure to pivot toward AI or sell to a larger company. The pricing is sustainable, $15/year covers infrastructure costs with healthy margins. Clockwise shut down because Salesforce acquired the team, not the product. Hetk doesn’t have that risk.

What if my company blocks third-party calendar apps?

Some Microsoft 365 tenants require admin approval for third-party apps. If you see “Need admin approval” when connecting Outlook, your IT admin can approve Hetk in one click. See our admin consent guide for step-by-step instructions. Personal Google and Microsoft accounts are never blocked.

How does Hetk compare to Reclaim.ai?

Reclaim is a full AI scheduling platform, it optimizes your calendar, schedules habits, and manages tasks. Hetk only syncs calendars. If you want AI scheduling, use Reclaim. If you just want your calendars in sync (which is what most Clockwise users actually needed), Hetk does it at $15/year instead of Reclaim Starter’s $120/year, and includes iCloud support that Reclaim doesn’t have.
