Getting started
On iPhone or iPad, tap + to create a blank sketch or import a file. You can also share an image or PDF from another app to SketchOn. Open an image and tap Sketch to draw on it and in the surrounding space. Use two fingers to pan, and pinch to zoom.
Sync between devices
Use the same Apple Account with iCloud enabled on each device. Open SketchOn and tap Sync. Local work remains on your device when offline and syncs when a connection is available. Allow enough iCloud storage for your files. Check that the app shows Saved to iCloud before expecting another device to receive a change.
Live drawing on Mac
Open the same synced sketch on Mac and iPhone or iPad. Allow local network access and connect the devices to the same network. Draw on iPhone or iPad to follow the drawing on Mac. Internet Live Drawing is an optional advanced feature that requires your own compatible secure relay and the same settings on both devices.
Export and recover notes
Open a note and use Export to save its original, a PNG, or an image-based PDF. Library options > Archive & Trash lets you restore notes or permanently delete them. Newly trashed notes are kept for up to 30 days before cleanup when SketchOn runs. An offline device applies synced changes after reconnecting.
Supported files
Import files up to 25 MB each. Images and blank sketches support editable drawing on iPhone and iPad. PDFs support viewing and sync; PDF annotation is not included. Mac provides library, preview, paste, live viewing, and export features.
