The problem

Work, study, side projects — you switch all day. 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 right away. Nothing installed, nothing running in the background.

03 / TRACK

Time tracks itself

Previous timer pauses. New timer starts. Your hours stay up to date on the screen — without a single click.

Context Switcher on a desk next to a keyboard
On your desk

About the size of a coaster.
Always within reach.

About 114 × 110 × 72 mm (prototype). Sits next to your keyboard. The only thing on your desk that knows what you're working on right now.

BluetoothConnection
USB-CCharging
Features

Designed for focus.

Instant desktop switching

Jump to any of your 6 virtual desktops with one turn. No keyboard shortcuts. No taskbar archaeology. One physical action: turn.

Automatic time tracking

Turn the knob — old timer stops, new one starts. Hours per project, always visible on the e-paper screen.

Bluetooth BLE 4.2

No cables. No dongle. Pair once.

All-day battery

LiPo with USB-C charging. About a day connected on the prototype; sleeps when your computer is away.

Windows today, Mac next

Pairs over Bluetooth. Nothing to download. Mac mode in development, included for every backer.

Zero distraction

E-paper shows everything you need.

Private by design

No cloud account. No telemetry. No data collection. Your project names, hours, and habits never leave your machine — period.

Works today

The device pairs as a standard Bluetooth keyboard and drives Virtual Desktops natively. No software, no drivers, no account — plug nothing in, install nothing.

macOS

In development · included for every backer

Same idea on Mac: it pairs as a standard Bluetooth keyboard and switches Spaces. The Mac mode is being built now, and we'll show it working in a campaign update before anything ships.

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?
Windows 10/11 works today. The macOS mode is in development and included for every backer. Any computer with Bluetooth (built-in or a cheap USB dongle) works.
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 e-paper screen, so you decide what it maps to.
When does it ship?
Estimated delivery: June–July 2027. Manufacturing starts only once the campaign is funded, and every step — including any delay — will be shared in campaign updates.
How much is shipping?
Shipping is charged separately after the campaign, at real cost, through Kickstarter's pledge manager. Estimates: Spain €6–8 · EU €11–14 · Switzerland/Norway €16–19 (local VAT paid on delivery) · USA €31–38 (import duties included). EU prices include VAT; US backers may be charged state sales tax by Kickstarter. We don't ship to the UK at launch.
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.
