Diagram your launch strategy on your dining table. Scribble a quick note on your desk. Sketch an idea for a mural on your bedroom wall. TouchDesk lets you overlay drawings and doodles wherever inspiration strikes.

What we love: Keeping TouchDesk open throughout the day as a place to jot down our thoughts. Drawing in the app is as simple as dragging your finger on any horizontal or vertical surface – and if you need more room, you can scroll the canvas in any direction.

Don’t miss: Customising the colour and size of the app’s pens, pencils and paintbrushes. There’s support for images, too, so you can add reference photos to aid in your brainstorm.

Quick tip: Want to quickly switch which hand you’re drawing with? Just look at the canvas and pinch with that hand.
