TL;DR
Aftertone: £20/mo or £100 lifetime. macOS productivity system — tasks, time blocking, Focus Screen, behavioural AI, weekly reports.
Chunk: $4.99/mo or $39.99 lifetime. macOS time blocking app. Clean design, routine templates, timer. No native task management, no AI, no weekly reports.
Key difference: Both are macOS time blockers with lifetime pricing. Chunk stops at the schedule. Aftertone adds tasks, a Focus Screen, AI, and weekly reports on top.
Chunk and Aftertone share some DNA. Both are macOS-only. Both offer lifetime pricing. Both are built by small, independent teams who think productivity software should be simple, fast, and bloat-free.
The difference is what happens after you create your time blocks. Chunk helps you plan your day and work through it with a timer. Aftertone does that and adds native task management, AI that learns your patterns, a Focus Screen that adapts while you work, and automated weekly reports that help you improve every week.

Where Aftertone pulls ahead
Task management is the biggest gap
Chunk doesn't have it. If a task comes to mind while you're working, you need to open a different app to capture it. In Aftertone, you hit a keyboard shortcut from anywhere on your Mac — the task is saved, tagged to a project, and out of your head. No flow broken, no thought lost.
AI that learns how you work
Chunk has no AI. It doesn't know which tasks you keep postponing, where your schedule slips, or when you do your best work. Aftertone tracks all of this silently. Every week you get a report: here's what stalled, here's where your time drifted, here's when your energy was highest, here's what to try differently. Use Chunk for a year and you have a year of time blocks. Use Aftertone for a year and you have a documented record of your productivity evolution.
The Focus Screen does real work
Chunk lives in your menubar — you check it while working in other apps. Useful, but your work environment is whatever else is on your screen. Aftertone's Focus Screen takes over when it's time to work. Current task, nothing else. Overdue? Flagged. Finish early? Pick your next task with 1-2-3 and your calendar updates automatically. You don't go back to your plan — the plan comes to you.
Two-way calendar sync
Chunk shows your Google and Outlook events as a read-only reference — your Chunk blocks don't write back to your calendar, so they're invisible to everyone else. Aftertone's Google Calendar sync is two-way and real-time. Your time blocks appear in Google Calendar. Your colleagues see them. Your availability updates automatically.
The Evaluate and Optimise phases
Chunk covers Plan and Execute. Aftertone adds Evaluate (automated analysis at the end of each week) and Optimise (AI suggestions for next week). Over time, this feedback loop compounds — each week builds on the insights from the last.
Where Chunk is the better fit
Chunk may be cheaper — it's a lighter tool with a lower price point. If all you want is a clean time block planner with a timer and no extra complexity, Chunk does exactly that.
The menubar design is convenient — always accessible without taking up screen space or requiring a window switch.
Chunk's template and routine system is well-built for people with consistent daily structures.
