Outcome Companion
A small desktop app that pairs with your iPhone and sources your PC gameplay into Outcome — so what you're playing shows up alongside the prediction markets that follow it.

What it does
A bridge between your PC and your iPhone, not a streaming studio.
The companion is small, single-purpose, and stays out of the way. You don't need to learn a new tool — you just connect once and play.
Auto-detected game library.
Scans Steam, Epic, and your running processes to find launchable games. Pick one and the companion knows what to capture.
Pairing in five seconds.
QR code on PC, scan with iPhone, done. Single-use code, expires in five minutes. No usernames or passwords typed across devices.
Low-latency stream to viewers.
Hardware-accelerated encoding (NVIDIA NVENC, AMD AMF, Intel QuickSync) keeps the companion off your game's CPU. Stream health is visible at a glance.
Console roadmap
Native console apps post-launch.
Console-first streamers don't need a PC in the chain. Native Xbox and PlayStation companions are on the post-launch roadmap.

Just want the iPhone app?
The Outcome iOS app waitlist lives on the home page.
You only need the companion if you want to source your own gameplay. Watching markets, predicting, and following streamers all happen on your phone — no PC required.
