Real keys, not shortcuts to shortcuts
Hotkeys, app launches, URLs, media keys, screenshots, typed text, chained macros — and shell commands, if you turn them on. Seven kinds of action, each doing the thing itself rather than pretending.
Deckon — your computer at your fingertips. One tap, total control.
Deckon turns the phone already in your hand into a control surface for your computer. Real keys, your own apps, and about two milliseconds — straight over your own Wi-Fi.

The short of it
Four numbers, and none of them
is a price.
Press to action
~2ms
A press is a JSON frame across your own Wi-Fi. Measured on a MacBook Air over LAN — round trip, not a marketing round number.
0
Servers between your phone and your computer. There is no Deckon cloud to be down, breached, or discontinued.

Kinds of key — hotkey, launch, URL, media, system, text and shell.

Drives all three, from an iPhone or an Android. One deck, whatever is on the desk.
What it does
A deck that knows what you
actually have installed.
Your apps, with your apps’ colours
Deckon reads what is installed on your Mac, pulls each icon at full fidelity, and samples a brand colour straight out of it. Spotify green, Chrome blue, Figma orange — a deck you can read at a glance. Windows and Linux list apps by name for now.
The transport key knows what is playing
On a Mac, Play becomes the track: title, artist, and the cover art blurred behind it — Spotify, Music, or video in a browser tab. Everywhere else the key still drives playback; it just does not yet report back what is on.
Approve agents from your pocket
When something on your machine needs a decision — a coding agent asking to run a command — the question arrives on your phone. Answer from anywhere in the room; the first answer settles it.
It reflows when you turn it
Portrait, landscape, phone, tablet: the grid is derived from the screen, not stretched to it. Keys stay square, keep their order, and whatever will not fit is one swipe away.
About two milliseconds
A press is a JSON frame over your own Wi-Fi. No relay, no queue, no round trip through anyone’s cloud — the phone does not even wait for the reply to feel pressed.
Make it yours
Four ways to draw a key.
The look is a per-phone choice, so two phones on the same deck can be completely different objects. Pick one and watch the deck below change.

Deckon Premium
Your phone follows
the app you are in.
Smart Decks gives every app — and every site — its own deck. Switch to Figma and your phone shows Figma’s keys; open Gmail and it is Gmail’s. From ₹49 a month at launch.
Put it on your desk.
Install the desktop app on the computer you want to drive, then pair the phone you already carry. The deck is built on the desktop; the phone is the surface.
On an Intel Mac? Download the Intel build. Every installer is also on the releases page.
The phone app is on the App Store and Google Play. It is free, and it needs the desktop app to do anything at all.
Deckon is on your desk.
HangOn is everywhere else.
The app for the rest of it: sessions worth turning up to, tournaments worth entering, and the people nearby who play what you play. Free, and from the same team that made this.
- Explore activitiesWhat is on near you, tonight or this weekend
- TournamentsFind one, enter it, follow the bracket
- Find nearby gamersSquads forming close enough to actually reach

Questions
The ones worth asking.
Does anything go through a server?
No. Pairing is a code exchange on your own network, and every press after it is a WebSocket frame between two devices on that network. There is no Deckon server to route through — the app does not have one.
What can a paired phone actually do?
Exactly what you put on the deck, and nothing else. A phone presses keys; it cannot define them. Keys are created and edited on the desktop, and any phone can be revoked from Settings, which kills its token immediately.
Do I need an account?
No. Pairing, editing and pressing all work with no account and no internet connection.
Is Deckon free?
Yes — the desktop app, the phone app and every kind of key. Smart Decks, which switches your deck to match the app in front, is an optional subscription.
What permissions does it need?
On macOS, Accessibility to send keystrokes and Screen Recording for screenshots — both requested only when a key needs them, and a key missing a permission tells you so instead of failing silently. Windows and Linux use the standard input tooling already on the system.
Are shell commands safe?
They are off until you switch them on, and then they run only the specific commands you wrote, only for a phone that is already paired. It is the sharpest thing in the app and it is opt-in for that reason.
Which phones work?
iOS and Android. The phone app is the surface; everything is configured on the desktop.
