Clockwise shut down on March 27, 2026.
TL;DR: Clockwise's shutdown leaves a two-part gap: internal calendar optimization (auto-blocking Focus Time, clustering flexible meetings) and external booking control (keeping new requests off protected slots). No single tool replaces both. Use Reclaim.ai (closest to Clockwise) for internal optimization, and configure Schedulee's booking rules — minimum notice, buffer time, daily limits, protected days — to keep external requests from colonizing your calendar.
Not acquired-and-kept-alive shut down. Actually gone. The Salesforce deal was an acqui-hire — the team went to work on Agentforce, the product disappeared. If you were one of the engineers, researchers, or ops people who lived and died by Clockwise's Focus Time blocks, you already know this stings differently than a normal tool switching.
Calendly going down would be annoying. Clockwise going down felt personal, because what it did was hard to replace with a single tool.
This post is specifically for Clockwise's core users: people who used it primarily to protect deep work time, not just to share a booking link. There's a separate post for general scheduling tool migration after Clockwise's shutdown — this one focuses on the focus time problem specifically, because the replacement strategy is different.
What Made Clockwise Actually Special
Most people describing Clockwise to someone who hasn't used it get it slightly wrong. They say "it's like Calendly but smarter." That's not right.
Clockwise was a calendar optimizer, not a booking tool. You didn't share a Clockwise link with external people. You installed it on your own calendar and it worked behind the scenes:
- It detected your flexible meetings (1:1s, optional standups) and moved them to cluster with other meetings, leaving bigger contiguous blocks
- It auto-created "Focus Time" blocks to fill open calendar space — and crucially, marked them as Busy so new meetings couldn't land there
- It integrated with Slack to set your status to Do Not Disturb during Focus Time
- It learned your preferences over time and stopped asking about the same meeting patterns
For engineers and anyone doing heads-down work, this was transformative. Your calendar went from Swiss cheese to 2-3 hour uninterrupted blocks that people couldn't schedule over.
The job it was doing: protecting your time from incoming external and internal requests, automatically, without you having to manually block every week.
That's a fundamentally different problem than "I need a way to let clients pick a 30-minute call slot."
The Replacement Isn't One Tool — It's Two
Here's the honest answer: there is no single replacement for what Clockwise did, because Clockwise was doing two distinct things.
1. Internal calendar optimization — rearranging flexible existing meetings, blocking focus time proactively, syncing Slack status. This is the core of what Clockwise did.
2. External booking control — ensuring that when new meetings land on your calendar, they respect your schedule rules: minimum notice, buffer time, meeting limits, no bookings on protected days.
Clockwise handled #1 natively and influenced #2 indirectly (by making focus blocks "Busy" so external booking tools couldn't place meetings there).
When you lose Clockwise, you lose both. You need separate tools to cover each.
For Internal Optimization (What Clockwise Actually Did)
The three serious options here:
Reclaim.ai — The most direct Clockwise replacement. Reclaim has a Focus Time feature that auto-defends calendar blocks, flexible meetings that can shift around your priorities, and Slack integration. They even ran a "switch from Clockwise, get 3 months free" offer when the shutdown was announced. The UX is busier than Clockwise and the AI is more configurable (which is a blessing and a curse). For former Clockwise users, this is the obvious first stop.
Motion — More aggressive: it reschedules your entire day automatically, not just flexible meetings. Motion treats your task list and calendar as a unified system. If you're comfortable handing over more control, the results can be dramatic. If you liked Clockwise's relatively light-touch approach, Motion will feel overwhelming at first. It's better suited to people managing projects across many meetings, less suited to engineers who just want long uninterrupted blocks.
Akiflow — A task + calendar hybrid that requires more manual input than either of the above. Less AI-driven, more of a discipline system. If you want to replace Clockwise's auto-blocking with something you control precisely, Akiflow works. It won't do the optimization for you, but it will make the manual process fast.
None of these are perfect Clockwise replacements. Reclaim is probably closest. The others serve different workflows.
For External Booking Control (Keeping External Requests Off Your Protected Time)
This is where a dedicated scheduling tool like Schedulee comes in — and where most Clockwise users haven't thought carefully about the gap they're now exposed to.
When Clockwise was running, it would mark your Focus Time blocks as Busy in Google Calendar. Any booking tool set to respect your calendar availability would see those blocks as taken and route requests around them. That protection evaporates the moment Clockwise stops running.
Without something actively filling those slots as Busy, clients, prospects, and even your own colleagues can start landing meetings during what used to be protected time. You'll notice it a week or two after the shutdown when your calendar starts looking like it did three years ago.
The right response is to set explicit external booking rules — not just "block some time on my calendar" but rules that govern how new meetings get onto your calendar in the first place.
How to Recreate Focus Time Protection in Schedulee
While you're sorting out an internal optimizer (Reclaim, Motion, or manual blocking), you can use Schedulee's booking rules to enforce hard constraints on when external meetings land. This doesn't replace Clockwise's dynamic optimization, but it prevents the worst-case scenario: a week where every remaining open slot fills up because nothing is defending them.
Here's the specific configuration that Clockwise users should set up:
Minimum Notice Period
Go to your meeting type settings and set a minimum notice period of 24-48 hours. Clockwise was good at defending your current-week schedule; without it, a minimum notice period does some of that work. Nobody can drop a meeting on you with 2 hours notice.
Buffer Time Between Meetings
Clockwise created buffers by clustering meetings together. Without it, set explicit before/after buffer times on each meeting type. 15 minutes before and after ensures that even if someone books your first available slot, you have transition time rather than back-to-back bookings starting immediately.
Daily Booking Limits
Schedulee lets you cap how many meetings of a given type land on any single day. If you previously relied on Clockwise to leave afternoons free, set a limit of 2 external meetings per day. This prevents the "all my openings filled on Tuesday" problem.
Available Days Configuration
Be explicit about which days accept which types of meetings. If you wanted Mondays and Fridays protected for deep work, go to your availability settings and simply don't offer those days for external bookings. Clockwise did this dynamically; doing it statically is less elegant but consistently reliable.
Meeting Type Segregation
Create separate meeting types for different purposes — a "Quick Sync (30 min)" with aggressive limits versus a "Strategy Call (60 min)" that requires 48-hour notice and only appears on specific days. Schedulee's team scheduling also lets you use round-robin assignment so not every external request lands on one person.
None of this is as automatic as Clockwise. Clockwise learned your patterns; this requires you to codify them yourself. But the advantage is that once you've set these rules in Schedulee, they're permanent and don't depend on any background process running correctly.
The Bigger Picture: What Clockwise's Shutdown Signals
Clockwise's team got acqui-hired to work on Salesforce Agentforce — specifically to build AI scheduling agents. That's worth sitting with for a second.
The future the Clockwise founders are building isn't a tool that defends your calendar. It's an agent that manages your calendar on your behalf — reading your goals for the week, your task backlog, your deadlines, and your energy levels, and actively negotiating meeting requests rather than passively accepting or blocking them.
That's a real shift. The booking-link model (someone picks a slot from your available windows) is a significant improvement over back-and-forth email. But an AI assistant that can say "Alex prefers not to take calls before 10am on Tuesdays because she's finishing the sprint review — let me suggest Wednesday" is a different category entirely.
Schedulee is building toward this. The current AI assistant features handle smart availability suggestions and conflict detection. The trajectory is toward agents that can handle more of the negotiation automatically — closer to what Clockwise's team is now building at Salesforce, but for the external booking context rather than internal calendar optimization.
For now, though, the practical path forward is the two-tool approach: an internal optimizer handling your calendar rearrangement, and a solid external booking layer with firm rules that keep new requests from colonizing the time you've protected.
The Setup Checklist (Before March 31)
If you're a Clockwise user scrambling to replace it before the muscle memory fades, here's the sequence that makes sense:
This week:
- Sign up for Reclaim.ai and enable Focus Time (it reads your Google Calendar directly, so setup is fast)
- Set up Schedulee if you haven't — create your core meeting types with minimum notice and buffer time enabled
- Manually block focus time on your calendar for next week as a stopgap while Reclaim learns your patterns
Next two weeks:
4. Tune Reclaim's flexible meeting settings based on how your actual week plays out
5. Review Schedulee's daily meeting limits and adjust based on how many external requests you typically get
6. Add the specific availability rules (no Mondays, capped afternoons, etc.) that Clockwise used to enforce automatically
Ongoing:
7. If you find Reclaim isn't optimizing aggressively enough, evaluate Motion as a more hands-on alternative
8. Revisit your Schedulee meeting types quarterly — meeting patterns shift, and static rules need periodic review
Final Thought
Clockwise losing the acqui-hire lottery is genuinely a loss for the category. There isn't another tool that did exactly what it did, at the price it did it, with as little friction. The people who will feel this most are engineers and researchers who were using it to maintain cognitive hygiene across a calendar that would otherwise degrade into 45-minute context-switch hell.
The two-tool replacement strategy works, but it requires more active maintenance than Clockwise did. That's the honest trade-off. The fully autonomous calendar agent is coming — the Clockwise team is building it at Salesforce right now — but it's not here yet for external booking.
What is here: a reliable way to enforce your scheduling rules so that when external requests come in, they land in places you've actually designated rather than wherever your calendar looks open.
Set up your Schedulee availability rules now — before the next person tries to book a meeting across your focus block.
Frequently Asked Questions
Is there a single tool that replaces everything Clockwise did?
No. Clockwise handled two distinct jobs — internal calendar optimization (rearranging flexible meetings, auto-blocking focus time) and external booking control. You'll need a calendar optimizer like Reclaim.ai for the first job and a scheduling tool like Schedulee for the second.
What's the best Clockwise alternative for engineers who need focus time?
Reclaim.ai is the closest match. It auto-defends focus time blocks, shifts flexible meetings, and integrates with Slack for Do Not Disturb status. Motion is more aggressive (it reschedules your entire day) but can feel overwhelming if you just want protected deep work blocks.
How do I stop external meeting requests from landing on my focus time?
Set explicit booking rules in your scheduling tool: block focus hours as completely unavailable, add minimum notice requirements (24-48 hours), enforce daily meeting limits, and add buffer time between meetings. Schedulee lets you configure all of these per meeting type so external requests only land in designated windows.
Will Salesforce rebuild Clockwise's features?
The Clockwise team is working on Agentforce at Salesforce, but any calendar optimization features they build will likely be part of Salesforce's enterprise platform — not a standalone tool. There's no announced timeline for bringing Clockwise-like features back in any form.
How long will it take to set up a replacement workflow?
The internal optimization tool (Reclaim or Motion) takes about 30-60 minutes to configure with your preferences. Setting up external booking rules in Schedulee takes under 10 minutes. Budget a total of one to two hours to replace the core Clockwise functionality, though you may spend a few weeks fine-tuning as you learn the new tools' behavior.
