Why Cue Lab is Best in Class

There are other pool diagramming apps out there—but none like Cue Lab. Here’s why we believe it’s the most powerful and intuitive pool diagrammer for iPhone and iPad:

• Fully optimized for iOS

Seamlessly works on both iPhone and iPad, adapting to the full screen so your fingers stay out of the way while drawing.

• Flexible export options

Export images in portrait or landscape, and share instantly via Instagram, Facebook, Messages, Notes, and any other iOS app that supports images.

• Smart, intuitive drawing tools

Create realistic shot paths with ease—balls bounce off rails and other balls just like on the table.

• Advanced path control

Illustrate complex shots with bending paths to show curves, arcs, and even massé effects.

• Precision features

Add a table grid, snap balls to intersections, and zoom in for pixel-perfect placement.

• Ready-to-play racks

Start from preset racks for 8-ball, 9-ball, 10-ball, and 14.1 continuous (straight pool).
