TL;DR
Aftertone: £20/mo or £100 lifetime. macOS productivity system — tasks, time blocking, Focus Screen, behavioural AI, weekly reports.
Sessions: Free (basic) or ~$5/mo. Focus timer combining Pomodoro technique with ambient music, task labels, and focus analytics. macOS, iOS, web.
Key difference: Sessions helps you focus during work blocks. Aftertone helps you plan, focus, analyse, and improve across your entire week.
Sessions is a dedicated focus timer app. Start a session, choose ambient music or silence, set your duration, and work. It tracks your focus hours, shows daily/weekly charts, and supports task labels to categorise what you're working on.
For pure focus measurement — "how many deep work hours did I do this week?" — Sessions is clean and effective. But there's no task management, no time blocking, no calendar integration.
Aftertone integrates focus into a broader system: time blocks, Focus Screen, behavioural AI, weekly reports. Sessions is one tool. Aftertone is the system.

Where Aftertone pulls ahead
A complete system
Sessions measures focus. Aftertone plans, focuses, analyses, and improves.
Task management
Sessions labels sessions. Aftertone manages tasks inside time blocks with a Focus Screen.
Behavioural AI
Sessions shows focus charts. Aftertone generates specific weekly improvement suggestions based on pattern analysis.
Where Sessions is the better fit
Sessions' ambient music integration is a genuine feature for people who need audio cues to enter focus. A curated selection of background sounds — rain, white noise, lo-fi — plays directly in the app alongside your focus timer. It's a simple combination, but having it built in means one fewer browser tab or separate app.
Clean focus analytics show daily and weekly deep work hours at a glance. If your goal is to hit a target — four hours of deep work per day, twenty per week — Sessions gives you an honest, automatic record of whether you're meeting it. That's more reliable than estimating from memory.
Sessions runs on macOS, iOS, and web. The iOS companion app is useful for checking your focus hours during the day without opening your Mac. Aftertone is macOS-only.
Sessions is intentionally lightweight — it doesn't try to manage your tasks, structure your day, or analyse your patterns. For people who have their task management sorted and just want a clean focus timer with good music, that simplicity is the point.
3-year cost comparison
Aftertone costs £100 once. Sessions costs approximately $60 per year — that's $180 over three years. By the end of year one, Sessions already costs more than Aftertone's lifetime price. Over three years, you'd spend 1.8× more on Sessions. Both are independently built tools. Only one lets you stop paying.
Who should choose Sessions
If you need cross-platform support beyond macOS, Sessions may be the better fit today. If you rely heavily on integrations with other tools in your stack, check whether Sessions connects to what you use daily. And if Sessions'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 Sessions better than Aftertone?
It depends on what you need. Sessions 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, Sessions 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 Sessions 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.
