TL;DR
Aftertone: £20/mo or £100 lifetime. macOS productivity system — tasks, time blocking, Focus Screen, behavioural AI, weekly reports.
Clockwise: Free tier or $6.75/mo (Teams). AI calendar assistant that optimises meeting schedules, protects focus time, and resolves conflicts. Works on top of Google Calendar.
Key difference: Clockwise rearranges your meetings to free up focus time. Aftertone gives you a system for using that focus time productively.
Clockwise is an AI layer on top of Google Calendar. It analyses your team's meetings and automatically moves flexible meetings to create longer blocks of uninterrupted focus time. It resolves scheduling conflicts, defends lunch breaks, and provides analytics on how your team spends time. It's popular with engineering teams and organisations trying to reduce meeting fragmentation.
But Clockwise is a calendar optimiser, not a productivity system. It creates the conditions for focus — longer uninterrupted blocks — but doesn't help you decide what to do during those blocks, doesn't protect your attention while working, and doesn't analyse your personal execution patterns.
Aftertone lives inside the focus time. Tasks in time blocks, Focus Screen for execution, AI that watches how you work, weekly reports. Clockwise frees the time. Aftertone fills it.

Where Aftertone pulls ahead
Execution, not just protection
Clockwise protects your focus time by rearranging meetings. Aftertone fills that focus time with a working environment — current task, overdue flags, 1-2-3 shortcuts. Clockwise creates the block. Aftertone lives inside it.
Personal behavioural AI
Clockwise's analytics are team-level: meeting load, focus time percentage, fragmentation. Aftertone's AI is personal: which tasks stall, where your time drifts, energy patterns. Individual vs organisational intelligence.
Native task management
Clockwise has no tasks. It moves meetings. Aftertone manages what you do between them.
£100 lifetime
Clockwise Teams is $81/user/year. Aftertone's lifetime plan is £100 total.
Where Clockwise is the better fit
Meeting fragmentation is a real problem in collaborative environments, and Clockwise solves it at the organisational level. It can move flexible meetings across a whole team to create longer uninterrupted blocks for everyone simultaneously. That coordination — rearranging Alice's meeting so Bob also gets a focus block — isn't something an individual can do unilaterally. Aftertone can't do this.
Team analytics give managers visibility into meeting load across their organisation — who's overloaded, who's under-meeting, where focus time is being fragmented. For team leads trying to protect their team's deep work time, that data is useful. Aftertone's analytics are entirely personal.
Clockwise works as a lightweight overlay. No new app to learn — just a Chrome extension connected to Google Calendar. If adoption friction is a concern for your team, Clockwise doesn't require anyone to change their existing workflow.
The free tier provides basic scheduling links and limited calendar optimisation. For smaller teams or individuals who want to test whether automated meeting rescheduling helps, there's no upfront cost.
3-year cost comparison
Clockwise is free — and for a free tool, it does its job. But free tools stay simple by design. Aftertone costs £100 once and delivers behavioral AI, Focus Screen, and weekly reports that a free tool will never offer. The question isn't cost — it's whether the free version gives you enough to actually improve how you work.
Who should choose Clockwise
If you need cross-platform support beyond macOS, Clockwise may be the better fit today. If you rely heavily on integrations with other tools in your stack, check whether Clockwise connects to what you use daily. And if Clockwise's specific approach — its unique features and design philosophy — matches how you prefer to work, it's worth trying.
But if you want a productivity system that goes beyond planning into execution, evaluation, and optimisation — with behavioral AI that learns your patterns and a Focus Screen that protects your attention — Aftertone goes deeper. And it costs less to own forever than most competitors charge per year.
Frequently asked questions
Is Clockwise better than Aftertone?
It depends on what you need. Clockwise has its own strengths — particularly if you need broader platform support or specific integrations. Aftertone is stronger on execution: its Focus Screen, behavioral AI, and weekly reports create a four-phase productivity system (plan, execute, evaluate, optimise) that most competitors don't attempt.
Does Aftertone work on Windows or Linux?
Not yet. Aftertone is currently macOS-only, built as a native Mac app for performance and deep OS integration. iOS and Android apps are in development. If you need Windows or Linux support today, Clockwise may be a better short-term choice.
Can I use Aftertone with Google Calendar?
Yes. Aftertone syncs with Google Calendar via two-way sync. Your time blocks, events, and schedule changes appear in both apps. Aftertone adds the productivity layer — tasks, Focus Screen, AI insights — on top of your existing calendar.
Is Aftertone's lifetime plan really one payment?
Yes. £100 once, then it's yours. No annual renewals, no price increases, no feature gates behind higher tiers. Every feature — behavioral AI, Focus Screen, weekly reports, unlimited projects — is included.
What if I'm switching from Clockwise to Aftertone?
Aftertone syncs with Google Calendar, so any events you have there will appear automatically. For tasks, you'll need to recreate them in Aftertone — but the keyboard shortcut capture makes this fast. Most users are fully set up within a day.
