🎯

Absolute aim, top-class latency

ARCore's visual-inertial tracking gives drift-free 6DoF aim, intersected with a one-time-calibrated screen plane and delivered through a 2ms newest-wins cursor loop — with live p50/p95 jitter stats to prove it.

🔌

Zero hardware

A Node server and your Android phone's Chrome. USB cable or the same WiFi network — both first-class, one command each.

🕹️

20 assignable buttons, edited live

A drag-and-drop editor maps buttons to any key combo or mouse button — applied to the PC and phone instantly, mid-session. Assign a screen edge (aim off-screen to reload, arcade-style) or a Bluetooth trigger to any of them.

🖥️

Multi-monitor support

Aim at one display or span them all — each monitor is calibrated as its own plane, so bezels and angled panels stay pixel-accurate, with independent aim correction per screen.

🧪

Tested to 90%+

TypeScript run natively by Node — no build step — with vitest enforcing 90% coverage on every metric, prettier, knip and husky gates.

📐

Calibrates on any screen

Aim at three corners, two taps each — the recommended two-ray method needs no trackable surface at all. Anchor-pinned hit-test mode, which keeps refining as ARCore learns the room, is one toggle away.
