For those who don’t know the tool: Sketchbook Pro is a lightweight drawing and paintover app for Windows and macOS, paired with a mobile sibling on iOS and Android. It also includes Flipbook animation inside the desktop app.
The headline features: two selection tools, less fiddling
Sketchbook Pro version 9.4 adds two tools built around selections: Lasso Fill and Draw Outline. Lasso Fill dynamically fills regions you define with the lasso and targets fast shape blocking for coloring workflows. It lives in the Fill sub-toolbar and can also work with Randomize Color. It can also run with Transparent Color as a clean-up move when you need to nibble back into an edge.
Draw Outline uses the current selection as a path to apply a stroke using the active brush and active color. The stroke centers on the selection line, and the tool sits in the Selection toolbar. It can push beyond plain outlines, including border and halo effects, glow-style results with softer brushes, and softer edge work with eraser-style strokes.
If your day job involves concept art paintovers and quick iterations, both tools aim straight at the boring bits: blocking, edging, and making a selection do something immediately useful.
Desktop release notes: flips, palettes, and Randomize Color behaving
Version 9.4 on macOS adds Layer Menu actions for Rotate CW, Flip Horizontally, and Flip Vertically. The Windows edition lists the same Layer Menu additions, along with the two new selection tools. Across both desktop platforms, color palettes now indicate the active swatch. The Fill tool, including solid fill and lasso fill, now works with Randomize Color instead of ignoring it. Draw Styles also work with Randomize Color.
Mobile builds: same core tools, Premium gate
On mobile, the new tools arrive in the Premium Bundle, not the free base app. On Android, version 6.2.5 lists Draw Outline and Lasso Fill as new Premium Bundle features. It also adds Copy, Cut, and Paste to the selection sub-toolbar, adds palette reordering in the Color Editor, and makes color palettes indicate the active swatch. The Fill tool now works with Randomize Color.
On iOS, version 6.2.6 lists the same two Premium Bundle additions and also adds palette reordering in the Color Editor plus active-swatch indication in palettes. iOS also notes fixes for brush information not populating in the double puck in 6.2.5, an export behavior where an Open button appeared during export of a TIFF file from the gallery, Glow blend mode alpha behavior, artifacts under groups with blend modes, and a canvas edit crop limit issue on very large dimensions. The Fill tool on iOS now works with Randomize Color as well.
The Premium Bundle itself is a one-time in-app purchase on iOS and Android. It unlocks more brush, color, and layer management features, including Lasso Fill, Draw Outline, layer grouping, clipping masks and alpha masks, adjustment effects, and multi-page PDF export. If you live in storyboard land, the selection-driven approach maps cleanly to the way boards get cleaned up: lasso, block, outline, move on. The main catch is that on mobile, you need Premium for the new toys.
As always, test new releases on real jobs, with real brushes, and with your worst legacy files before you bet a deadline on them. Your future self will thank you, or at least complain less loudly.
