Aftertone vs Chunk (2026)
TL;DR
Aftertone: $30/month. macOS productivity system — tasks, time blocking, Focus Screen, behavioural AI, weekly reports.
Chunk: $15.99 lifetime. macOS menubar time blocking app. Clean design, Todo mode, routine templates, timer, Claude MCP integration. No AI insights, no Focus Screen, no weekly reports.
Key difference: Both are macOS-only with lifetime pricing. Chunk is a lightweight menubar planner with Todo mode and two-way calendar sync. Aftertone adds a full task system, a Focus Screen, behavioural AI, and weekly reports that help you improve every week.
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 depth is the biggest gap
Chunk now has Todo mode — task lists that live in the sidebar and can be dragged onto the timeline. It also pulls in your Apple Reminders lists. For basic task capture alongside time blocks, it works. What it doesn't have is the depth Aftertone offers: keyboard shortcut capture from anywhere on your Mac, project tags, status tracking, filtering, and tasks that are calendar-aware rather than simply schedulable. If a task comes to mind mid-flow, Aftertone captures it, tags it, and keeps it out of your head. The difference is between task lists that sit beside your schedule and tasks that are woven into it.
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 is significantly cheaper — $15.99 lifetime vs $30/month. If you want a lightweight menubar time block planner with a timer, two-way calendar sync, and no extra complexity, Chunk delivers exactly that at a price that's hard to argue with.
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.
Who should choose Chunk
If the Claude Desktop MCP integration appeals to you — planning your day in natural language, with your data staying local on your Mac — Chunk's approach is genuinely distinctive. If you want the lightest possible footprint, a menubar utility that stays out of your way, and you don't need AI-generated weekly reports or a Focus Screen for execution, Chunk is the right choice at a fraction of the cost.
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.
Frequently asked questions
Is Chunk better than Aftertone?
For lightweight daily time blocking at a one-time cost, Chunk is a genuinely strong choice — $15.99 lifetime, two-way calendar sync, Todo mode, and a Claude MCP integration that lets you plan in natural language. For a full productivity system with behavioural AI, a Focus Screen that adapts mid-session, and weekly reports that compound over time, Aftertone goes significantly further. Neither is objectively better — the right choice depends on how much system you want around your time blocks.
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, Chunk 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.
How much does Aftertone cost?
Aftertone is $30/month with a 7-day free trial — no card required to start. Every feature is included: Focus Screen, Smart Capture, Smart Zoning, behavioural AI, weekly and daily reports, and unlimited projects.
Does Chunk have AI features?
Chunk has a local MCP (Model Context Protocol) server that connects to Claude Desktop. Once connected, you can ask Claude to read your schedule, create time blocks, move events, or delete entries — all in natural language, with your data staying on your Mac. It's a different kind of AI integration from Aftertone's built-in behavioural AI: Chunk's is conversational and on-demand, while Aftertone's runs silently in the background, tracking patterns and generating weekly reports automatically without any prompting.
What if I'm switching from Chunk 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.
Does Chunk have task management?
Chunk has a basic Todo mode that lets you capture tasks from the menu bar without leaving your current app. It’s not a full task manager — no projects, no filtering, no status tracking — but it handles quick task capture alongside your time blocks. Aftertone’s task layer is significantly more capable: keyboard shortcut capture from anywhere on your Mac, project tags, filtering, status tracking, and tasks that live natively inside your calendar view.
