Floating pen dock
A small draggable pen icon opens the toolbar and keeps the screen clear while presenting.

Support and demos
Guide someone through a screen by pointing, marking, and clearing quickly.
Privacy and beta tracking
Counts installs, not your screen.
InkPen sends a small anonymous launch ping once per day so we can understand how many beta devices are active.
- Sent: install ID, app version, macOS version, Mac model, architecture, display count.
- Not sent: screenshots, drawings, files, app content, names, emails, or exact activity.
- Screenshot capture is intentionally removed from the public beta and planned for a later signed release.
Public beta
Download InkPen for Mac.
Install the beta, open InkPen from Applications, and the floating pen toolbar appears on screen. For now, the app is free while public testing is active.
