Sketch. Simply.

A detailed sketch by Dave Brasgalla

Why Linea?

Sometimes you can do more with less. Modern drawing apps are powerful, but they can overload you with choices. Hundreds of settings, millions of colors, and infinite layers all lead to complex interfaces that make simple sketches time consuming and frustrating.

Linea takes a different approach. It gives you the right balance of power and control to sketch effortlessly. The focus stays where it belongs: on your creations, not the tools. Controls stay "at the fringes" until needed, but still provide the flexibility to change as needed.

A sketchbook isn't complicated, so why is your iPad?


Picking colors has never been simpler. You can choose from a wide range of pre-defined colors, or customize colors with a single tap. Linea automatically generates tints and shades with controls that are simple to understand.

Every control in Linea is designed to stay out of your way. Many drawing apps overload you with settings, popovers, and other widgets. Linea's elegant interface puts the focus where it belongs – on your ideas.

Linea provides a simplified set of layers. A total of five layers, which can easily be rearranged, merged, and adjusted, gives you plenty of flexibility for your projects. It’s a supercharged sketchbook.

Grids and templates bring your ideas and concepts to life. Whether it's showing traditional grids, 3D isometric lines, storyboards, or templates for iOS screens / icons, Linea helps guide your work. You can also customize the paper used as a background.

Sketches are a starting point. Export your work as a layered Photoshop document, transparent PNG, or JPEG file. With support for iOS sharing, it's easy to get your drawings into Slack, Dropbox, and other services. And if some of your sketches are duds, Linea's cropping feature can pick out the best parts.

Have you ever used your finger to erase a whiteboard? Linea includes a traditional eraser tool, but its revolutionary Touch Eraser lets you quickly fix mistakes without switching tools. Just wipe the screen with a finger – and the best part is your hand stays clean!

The first sketch app designed for Apple Pencil

Linea was designed from the ground up for this revolutionary input device. And if a Pencil isn't available, the app still works great with your finger.

Jennifer Bishop

“Linea is minimalistic in the best way, as the focus is the canvas and not a screen full of tools that I may never use ... it has been the perfect drawing app for an artist like myself that is used to a traditional medium but who is transitioning into digital art.”

Jennifer Bishop — Rainy Day Doodle

David Lanham

“Linea is simple enough to get your thoughts down without getting in the way and also able to allow for refinement through layers and editing. The included grids are perfect for exploring interface or icon ideas that will be ready to translate to final renders.”

“It's my new favorite sketching app!”

Serenity Caldwell, iMore

“The Iconfactory describes [Linea] as aiming for the simplicity of a paper sketchbook, and I think they’ve nailed it.”

Daring Fireball

“The color swatch in Linea is fantastic...It fits a spectrum of color options into a very compact space.”

9 to 5 Mac

“The best possible sketching experience whether you are drawing, prototyping an app interface, storyboarding, taking notes, or something else.”


“Linea is approachable for all – and will quite likely prove to be useful and enjoyable by all.”


“A dead-simple, natural sketching experience.”
