iPattern is a vector illustration app designed from scratch for the iPad. It supports paths, compound paths, text, images, groups, masks, gradient fills, and an unlimited number of layers.

iPattern was designed with performance in mind – it can easily handle drawings with hundreds to thousands of shapes without bogging down. Export your finished illustrations directly to your Dropbox as SVG or PDF.

Features:

• Very high performance. Select, scale and rotate hundreds of objects with zero lag.
• Create arbitrary bezier paths with the Pen tool.
• Create compound paths, masks and groups.
• Create text objects.
• Place photos from your albums.
• Boolean operators on paths (Unite, Intersect, Exclude, Subtract Front)
• Powerful scale and rotate tools.
• Gradient fills with interactive editing on canvas.
• Arbitrary stroke dash patterns.
• Swatch library.
• Unlimited layers per drawing.
• Rename, rearrange, delete, hide and lock layers.
• Adjust layer transparency.
• Snap to grid, points, and path edges.
• Isolate the active layer for easy editing.
• Email drawings as SVG, PDF, PNG and JPEG.
• Send SVG, PDF, PNG, and JPEG directly to your Dropbox.

iPattern requires iOS 7. It is available on the App Store.

One of my motivations for releasing the source code for Inkpad was to make it a community project. To that end, I'd appreciate help with bug fixes, new features, localizations, testing, and ideas for improving/simplifying existing code. Take a look at the list of issues to find enhancements that I've considered implementing. I'm also interested in your feature ideas.

If you're taking on a big change, I'd be happy to discuss design ideas or answer questions before you get too far along. Note: I will likely be picky about implementation details and UI changes.
