The problem

You manage 4 clients, 3 side projects, and a full-time job. Your time tracker doesn't know where you are.

Every context switch is manual. Click the taskbar. Find the window. Every single time.

How it works

Three seconds. Zero friction.

01 / TURN

Rotate the knob

Turn the encoder to your next project. The e-paper display highlights it with a live timer and large project number — crisp even in direct sunlight.

02 / SWITCH

Desktop jumps

The device sends the switch straight over Bluetooth BLE and your desktop changes in under 100ms. Nothing installed, nothing running in the background.

03 / TRACK

Time tracks itself

Previous timer pauses. New timer starts. Your hours are always accurate, always up to date — without a single click.

On your desk

Smaller than a coaster.
Always within reach.

114.5 × 110 × 71.5 mm. Sits next to your keyboard. The only thing on your desk that knows what you're working on right now.

FAQ

Questions, answered.

Do I need to download an app?
No. The Context Switcher pairs as a standard Bluetooth device — the same way a keyboard or mouse does. There is no app to download, no driver, no account and no background process. Turn it on, pair it once, and it works.
Will it work with my PC or Mac?
Yes. Standard Bluetooth BLE 4.2 — any computer with built-in Bluetooth or a cheap USB BLE dongle works. No special hardware required.
What if I use fewer than 6 projects?
No problem. Use as many slots as you need; unused ones stay blank. Each slot is just a number on the OLED, so you decide what it maps to.
When does it ship?
Targeting 4–5 months after the campaign funds. Manufacturing starts only once we hit the goal — this protects both us and backers. Exact dates confirmed during the campaign.
Is there a subscription?
No. One-time purchase, no cloud account, no monthly fee, no telemetry. Your data stays on your machine.
Can I export my tracked hours?
The device itself only shows live timers on-screen — there is no app or account to export from.
