Looking for the app that runs Steam games on Android? That is a different project that happens to share the name: Droid-Deck/DroidDeck. This one turns your phone into a button deck that controls a Windows PC.
Set up a grid of buttons on your phone that fire shortcuts, open apps, control audio and media, drive Discord and OBS, play sounds and switch your smart lights. The PC side is a small tray app; the phone talks to it over your local network.
- Free and open source — no subscription, no limit on the number of buttons or pages.
- No sign-up, no cloud — DroidDeck itself needs no account; the phone talks straight to your PC on the local network.
- Integrations built in — Discord, OBS, Spotify, Twitch, YouTube, Home Assistant and Tuya work out of the box, with live state on the buttons. No plugins to hunt down.
- Edit on the big screen — a drag-and-drop configurator in the PC's browser; changes reach the phone instantly.
- Updates itself — the Windows app installs new versions in the background.
| ⌨️ Shortcuts & apps | Send key combinations, open programs, files and URLs, run PowerShell/Python/.bat scripts, chain steps in a multi-action (with conditions), call webhooks and APIs. |
| 🪟 Windows | Switch the default audio device (headphones ↔ speakers), lock, sleep, turn the screen off. |
| ⏱️ Timers | Countdown, stopwatch, pomodoro and counters with a live clock on the button. |
| 🎮 Steam | Pick an installed game and the button gets its cover; tap to launch it. |
| 🗂️ Profiles | Folders, long-press and double-tap actions, automatic switching by the focused app, .droiddeck backups, and an offline copy of the deck on the phone. |
| 🔊 Audio mixer | Mute apps, change device volume, toggle the mic. The phone also has a full per-app mixer. |
| ⏯️ Media | Play/pause, next, previous for whatever is playing in Windows (Spotify, browser, players). |
| 📊 Live monitors | CPU, GPU, RAM and network gauges that update every second. |
| 💬 Discord | Mute/deafen, join channels, voice volume, push-to-talk, per-user volume, native soundboard. |
| 🎥 OBS Studio | Scenes, recording, streaming, virtual camera, replay buffer, mute and show/hide sources, filters, chapter markers, screenshots — with live state. |
| 🎵 Soundboard | Search and play sounds from MyInstants, routed to your mic through VB-Cable. |
| 💡 Smart home | Home Assistant, and Tuya / Smart Life lights, plugs and switches — toggles, dimmers and colours, with real state. |
| 🎧 Spotify | Player, like, shuffle, playlists and the album cover on the button (Premium). |
| 📡 Twitch & YouTube | Markers, clips, ads, polls and chat; live status and viewers. |
| 🔁 Two states & info | Toggle buttons with their own icon and label; clock, weather, now playing, Windows notifications, command output and URL values on a button; record macros from the keyboard. |
| 🎚️ Sliders & big buttons | Volume sliders for the PC, the mic or one app; buttons that span several cells; animated GIF icons. |
| 🤖 Automations | Press a button by itself at a set time, when an app opens or closes, or when the PC wakes up. |
| 📥 Import & share | Import Elgato Stream Deck profiles, share a profile by link or QR, start from the profile gallery. |
| 🖥️ Several PCs | Pair one phone with more than one PC and switch from the deck's top bar. |
| 📱 iPhone, iPad & USB | Use the deck in any browser (iPhone, iPad, another PC) through a QR code, or connect an Android phone over a USB cable, no Wi-Fi needed. |
| 🎨 Themes | Ready-made themes, light/dark mode, accent colour and three button styles. A "deck only" mode opens straight into a full-screen deck, and buttons can vibrate on tap. |
You need both parts: the Windows app (it does the work) and the Android app (the buttons). The phone app alone does nothing. On an iPhone or iPad, use the deck in the browser instead of the app.
Requirements: Windows 10 1809+ (64-bit) · Android 7.0+ (or any browser, for iPhone and iPad) · phone and PC on the same local network, or an Android phone on a USB cable.
- Windows — download and run
DroidDeck-Setup.exefrom the latest release. It lives in the system tray and updates itself. (Prefer no installer? UseDroidDeck-win-x64.zip, extract it and runDroidDeck.exe.) No .NET install needed. - Android — install
DroidDeck.apkfrom the same release. - Pair — right-click the tray icon → Parear dispositivo (QR)… and scan the code with the app.
- Configure — open
http://localhost:4787/on the PC to edit your buttons. Changes show up on the phone instantly.
Note
The app follows the phone's language (English, Portuguese, Spanish or Hindi; anything else gets English). The documentation is available in both.

This is a monorepo with both halves of the project, which evolve together:
DroidDeck/
DroidDeck/ C# backend (.NET 8 / WinForms tray + ASP.NET Core + SignalR). Serves the API and the web configurator.
app/ Flutter app: phone runtime + web configurator (same codebase).
tests/ Backend tests.
scripts/ Utilities (deploy the web build to wwwroot).
website/ Landing page + documentation (MkDocs, EN/PT) published to GitHub Pages.
App and backend share a contract: REST (/api/...), SignalR (/deckHub) and UDP discovery
(port 7573), authenticated with an API key obtained through QR pairing.
# Backend: tray app + web server at http://localhost:4787
dotnet run --project DroidDeck
# Web configurator: flutter build web + copy to DroidDeck/wwwroot
.\scripts\deploy-web.ps1
# Android APK
cd app
flutter build apk --debug --target-platform android-arm64Backend modes: default (tray), --headless (server only), --print-pairing (prints the pairing URI/QR and exits).
