APPS // 2026 // SPY-C
A private, floating big screen.
NeoSentinel turns USB-C AR glasses into a head-tracked virtual display for your phone. Plug in, tap Engage, and a giant screen only you can see holds steady in the room around you.
THE PITCH
A personal cinema and workspace, anywhere you plug in.
AR glasses give you a huge display, but a screen that drifts with every head turn is useless. NeoSentinel pins it in place: live pose data from the glasses' 3-axis IMU anchors the mirrored screen in 3D space, so it stays put on a plane, a couch, or a desk. It's a giant screen only you can see, and it works in seconds over a single USB-C cable.
THE CORE LOOP
Plug. Engage. Escape.
- 01
Plug in
USB-C detection recognizes the RayNeo Air-series glasses by hardware id and unlocks the Engage button.
- 02
Engage
One tap boots the glasses SDK, starts IMU streaming, and mirrors your phone to a floating screen via MediaProjection.
- 03
Look around
3DoF head tracking anchors the screen in the room, so it holds still relative to the space as you turn your head.
- 04
Recenter
Snap the screen back in front of your gaze at any time. It auto-recenters the moment you put the glasses on.
WHAT'S INSIDE
More than a mirror.
Head-tracked big screen
Your phone, mirrored onto a giant virtual display anchored in 3D space by the glasses' built-in IMU.
Controller Mode
Turn the phone into an in-air laser pointer, aim at on-glasses tiles and launch other apps without touching the screen.
Tune the view
Dial in distance, size, and sharpness, toggle anti-aliasing, and switch between screen-fixed and head-follow modes.
Immersive scenes
Swap the empty passthrough behind your screen for a skybox like Amethyst Nebula, or load your own cubemaps.
Runs in the background
A floating quick-control widget, minimize with the session live, and a battery helper that keeps long sessions alive.
Free, with a way out
Ad-supported, with a rewarded-ad path to a 24-hour ad-free window, or a one-time Lifetime Pro to remove ads for good.
DIAL IT IN
Fine-tune your view, maximize immersion.
Every control lives one tap away, so the screen sits exactly where and how you want it.
