WatchPen
Notes you write on your watch
Free · Designed for iPhone. Not verified for macOS.
Jot a quick handwritten note on your Apple Watch — it syncs to your iPhone in seconds.
Capture short handwritten notes directly on your Apple Watch. Each note syncs to your iPhone automatically through your private iCloud — no typing, no third-party accounts, no setup beyond signing into iCloud.
WatchPen is built for moments where reaching for your phone is too slow. Lift your wrist, jot a thought with your finger, and the note is waiting on your iPhone moments later. Share any note as a PNG straight from the iPhone viewer.
Features
- Handwriting capture on Apple Watch
- Automatic iCloud sync to the paired iPhone
- Lightweight iPhone viewer
- One-tap share as PNG
- No accounts, no tracking, no analytics
Your notes live in your own iCloud private database. Nothing is collected or shared.
