How the free trial works
Core features
No subscription, no locked-in hardware, and your screen stays on your local network. These four are the core.
Extend or mirror your computer screen to a tablet or phone — an extra display for references, toolbars, or mirrored presenting.
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.
Send files between your computer and mobile device, and copy-paste across both.
Use your tablet or phone's touch and stylus to operate, draw and annotate, then save back to the computer — turning the device beside you into a drawing and handwriting pad.
Cross-device
Computer (Windows / macOS) × mobile device (iPhone / iPad / Android), mixed and matched freely.
Plans
The free tier is always available; Pro unlocks the dedicated e-signature. All features free for 30 days, with a 14-day money-back guarantee after purchase.
