Flow: Note Taking, Drawing Pad

Flow 4.1 brings a brand-new drawing tool, smarter ways to work with colours, and refinements that make creating in Flow even smoother.

Crayon
Meet our newest drawing tool: the Crayon. It’s fun to use, with a rich, textured look that’s perfect for adding warmth and personality to sketches, notes, and illustrations. Find it by opening the Tool Editor and scrolling to the bottom of the tool types.

Colours
Create colour variations
When you tap Add Colour in the Colours Panel, you’ll now see tint, shade, and harmonic variations — giving you quick, ready-to-use options without having to adjust them manually. To tidy up, simply press and hold on a colour until it pops away.
Create colours from an image
Turn inspiration into action by generating a colour set from any image. Open the Colours Panel options menu, tap the image button, and Flow will pick the most prominent colours so you can instantly create palettes that match your photo, artwork, or design mood.

Reference images
Keep your reference material right where you can see it without cluttering your document. Pin images above your page by dragging them in from another app or using the Add button in the top menu. Reference images stay visible while you work but aren’t saved to your document. Key colours from the image are shown automatically — tap to use one instantly, or import them all. The Colour Eyedropper works directly on reference images. You can also “pop out” an image from your document: select it with the Lasso Knife, then tap the pin icon.

Pencil Pro squeeze
Apple Pencil Pro users can now customise the squeeze gesture to switch to eraser, select with the Lasso Knife, or open the Tool Editor — so your favourite tools are always just a squeeze away.

UI panels
Boost the size of tools in the Tool Dock and colours in the Colour Panel for easier selection. On iPhone in Pencil Case mode, tools display larger for better visibility. All panels (Tool Editor, Tool Dock, Colours, Layers, Pasteboard) can now match your page colour for a cleaner look.

Pasteboard
Resize the Pasteboard Panel to suit your workflow. Narrow for a single-column view, or expand to two columns for larger previews.

Layers
Resize the Layers Panel from its corner for better visibility. The dock button remembers your last-used side, with a quick switch button when docked. Delete layers instantly with the new button beside the add button.
