OneX Inbox is the fastest email in the universe. Open, search, send — done before other inboxes finish their loading animation.
From click to a fully rendered message. The blink of an eye takes 100ms — OneX beats your eyelids by nearly 3×.
Full-archive search, updated on every keystroke. Ten years of mail, indexed on your device, answered before the key comes back up.
The app opens faster than your finger leaves the icon. No splash screen — there's nothing to wait for.
Your whole inbox lives locally. Planes, tunnels, and dead zones feel exactly like fiber.
The entire app weighs less than one photo attachment. Speed you can measure in megabytes too.
Triage a hundred emails without touching the mouse. Archive, reply, snooze, and jump folders with single keystrokes — each one lands in under a frame.
Spinners, skeletons, and progress bars in the entire app. We simply never needed them.
Time from click to fully rendered message. Median of 1,000 trials, identical hardware and network, February 2026.
You'll check email thousands of times this year. OneX makes every single one instant — and gives you your seconds back.
