A native Jetpack Compose client and a native Windows host that runs on Windows Home. Up to 4K 120 fps with 4:4:4 chroma, touch and S Pen forwarded to the desktop — pair once with a 4-digit PIN. No Microsoft or Google account.
Microsoft's Remote Desktop needs a Pro edition to host and caps around 30 fps; Google's tools need an account and relay through Google. Remio brings a native C++/WinRT host that captures with DXGI and hardware-encodes on your GPU — NVENC, AMF, or Quick Sync — streaming up to 4K 120 fps with 4:4:4 chroma and audio in sync. Home editions included, with no Pro upgrade and no account. See the Windows 11 Home remote desktop page for why that matters.
4:4:4 chroma keeps small text sharp — code, spreadsheets, and fine UI don't smear.
The client is Kotlin and Jetpack Compose — no WebView, no cross-platform bridge. Video hardware-decodes through MediaCodec onto a dedicated SurfaceView, so it holds a real 60 fps on a Pixel, Galaxy, or foldable. Touch maps to a native Windows pointer (long-press for right-click, pinch to zoom, two-finger scroll), the S Pen forwards with pressure and tilt on a Galaxy tablet, and Bluetooth keyboards and mice pass through as native Windows input.
Its layout adapts to a phone, a tablet, or a foldable's split view automatically.
Two installs, one PIN, no account. No VPN, no port forwarding, no router homework.
On the PC you want to reach, download the Remio host from remio.net/download and run it. It's a native C++/WinRT app that runs on Windows 10 (build 19041+) and Windows 11 — Home editions included, no Pro upgrade or registry patch.
Get the native Android client from the Play Store, or open remio.net/download on the device. Launch it — no signup, no email confirmation. It opens straight to a pairing screen with a number pad and a QR scanner.
The Windows host shows a one-time 4-digit PIN and a QR code that expires in 60 seconds. Scan or type it on the Android device, then tap the PC to connect. Remio picks the best route automatically — direct peer-to-peer, or an encrypted relay if a direct path isn't available. Add Wake-on-LAN and unattended access to reach a sleeping PC.
No RDP, no port forwarding, no exposed inbound port — just two apps and a PIN.
The host is a native C++/WinRT app on Windows 10 (build 19041+) and Windows 11, Home editions included — no Pro upgrade, no registry patches, no edition check. Every feature works on Home.
After the first pairing, reach the PC over mobile data or any Wi-Fi with peer-to-peer NAT traversal — no ports opened, no router touched. An encrypted relay carries the session when a direct path is impossible.
Sessions are end-to-end encrypted with AES-256-GCM and ECDHE key exchange over Curve25519. Keys live only on the two paired devices; a relay only ever forwards ciphertext it cannot read.
Input-to-pixel latency measures under 5 ms on the same network and around 22 ms same-region over the internet, both verified May 2026 — direct peer-to-peer when a path exists, relay only when NAT blocks it.
If one of these looks like your week, the five-minute setup above is all that stands in the way.
Hardware encode on the PC and hardware decode on Android keep the full frame rate, so a Galaxy Tab becomes a screen for the gaming rig in the other room. The gaming page covers the tuning, and there's a companion piece on playing PC games on a tablet.
Kick off the render before you leave, restart the stuck service from the train, approve the installer dialog holding everything up. A six-inch window is enough for the jobs that take minutes — and the session stays end-to-end encrypted over cellular the whole way.
Open their machine from your phone, fix it while they watch, and talk them through it — the use-cases page and the guide to fixing a computer from 500 miles away cover the setup end to end.
Microsoft's Remote Desktop usually caps around 30 fps and needs port forwarding, a VPN, or an RD Gateway to reach from outside; Chrome Remote Desktop also tops out near 30 fps and relays through Google's servers. Remio is native, 4:4:4-sharp, and free, with no account on either end. See Remio vs Microsoft Remote Desktop, Remio vs Chrome Remote Desktop, or the full compare hub.
One build, every feature — no feature gate, no trial clock, no usage detector.
Five questions the Android-to-Windows direction tends to raise — honest answers below.
Install the Remio host on the PC, install the Android client on your phone or tablet, pair once with a 4-digit PIN — free, works on Windows Home, no account.
