Core features

One buyout, cross-platform, all in.

No subscription, no locked-in hardware, and your screen stays on your local network. These four are the core.

Second screen

01Screen extend / mirror

Extend or mirror your computer screen to a tablet or phone — an extra display for references, toolbars, or mirrored presenting.

Dedicated UX

02Dedicated e-signature

Select, fill, sign. Mark the signature field on your computer, blow up just that region to fill the whole phone screen, and sign at full size — your strokes appear on the computer as you write. No zooming, no aligning.

About Beta testing ↗

Beta is invitation-only. It uses the same app; access and features follow the approved test program.

USD prices include applicable taxes. Paddle (Merchant of Record) itemizes tax at checkout: US$14.99 total early-bird, or US$19.99 standard.

Privacy

Local-first. Your screen never goes to the cloud.

Your screen content, files, clipboard and signature strokes are transmitted only over your local network — never through our servers, never to the cloud. Payments are handled by Paddle; we neither receive nor store your card details.
