Maintained and supported by husband and wife team, Derek and Lindsay, Inkpad is all about creating beautiful vector artwork.

Derek Pollard

With over twenty years of software development experience, Derek has been inspired by the success of the iPhone and iPad and the opportunities to share software in the App Store. With his trusty office gerbils he designs and develops enhancements to Inkpad.

Lindsay Pollard

Having worked for several years in website and graphic design, Lindsay uses her creative experience to help Derek. Together with her team of rats, Lindsay creates the sample images, contributes feature requests and is the Inkpad chief bug tester!


Inkpad was originally created by Steve Sprang in 2011, following on from his success with the art package Brushes. In 2013 he released it as Open Source with the intention of it being taken over as a community project. Unfortunately the Inkpad project went unmaintained for roughly 2 years and the original app was removed from the App Store.

With the disappearance of the Inkpad app we took over development and support in 2015 because both of us use Inkpad - you can see some of Lindsay's artwork in the app screenshots and samples. We wanted to ensure the continued development and support of a product we and others enjoy so much.

This version of Inkpad was originally based on the Open Source project. Over the years, with ongoing maintenance, additional features and the adoption of new Apple technologies, such as Metal and Swift, that source code has been replaced. Inkpad still has a similar user interface experience, ease of use and backwards compatibility for the original drawings.

Resources still used from the original project are as follows:

Source code

Livarot C++ library for operations on polygons and computing voronoi diagrams.


Mushroom Breakdown, Toucan in the Shade and Space by Ron Letkeman.

Help documentation

Help text, localisations and some images.


Chinese Simplified, French, German, Italian, Japanese, Portuguese, Spanish, Turkish.
