Dejal has provided many quality and flexible utilities to the Macintosh world over the years, starting back in 1991 with the pre-Mac OS X gems QuickEncrypt and SndConverter Pro. Nowadays, pretty much everything is developed in native Cocoa for Mac OS X, including Simon, Time Out, Caboodle, Narrator (which was acquired by Mariner Software), and more, and for iPad, iPhone and iPod touch, including Tweeps and others. In addition, Dejal provides consulting and contract programming services to help others produce great Mac OS X and iOS software. Plus Dejal gives back to the community by making sample code available for developers.

Established in Auckland, New Zealand in September 1991, Dejal moved to Portland, Oregon, USA in April 2001 and was organized as a Limited Liability Company (LLC) in April 2002. The name "Dejal" is pronounced DEE-JILL - see the FAQ for more information.

Just For You

David's customers are his friends, so he carefully guards your privacy, and is confident that you will love his products, so he offers a 100% satisfaction guarantee on everything.

To provide the best possible support, David provides prompt, friendly and FREE support via the Dejal Forums and via email for all his products. You get helped by the guy who wrote the product, so knows how it ticks, and can whip up a quick fix if necessary. David makes blog posts about product releases, Mac topics, and other discussion. And you can show your support of Dejal with official merchandise, including T-shirts, mugs, caps, and more!

Dejal software is not sold in stores. David keeps prices affordable by avoiding the old-style packaging and distribution channels. Instead, all Dejal Mac software is available for online download via the Dejal web site. All products include a full-featured FREE trial period to allow you to see what you're buying beforehand. iPad and iPhone apps are of course only available via the iPhone App Store, but all include free Lite editions so you can try fully functional editions before deciding to purchase the paid Pro edition.


The Dejal logo was created by graphic designer Emily Pfeifer. It is a highly-stylized capital "D", and also somewhat resembles a wave (representing progress) and a kiwi bird (for Dejal's country of origin).

This website was designed in-house by David. This latest rendition is a blend of hand-crafted pages and Drupal-based pages. The hand-crafted pages are maintained in Coda using strict-XHTML, with Cascading Style Sheets, and served up by PHP scripts to allow dynamically updating version number displays, a standard header and footer without the evil of frames, and several other nifty features. The Drupal-based pages are served up by the Drupal Content Management System, which uses a database backend driven by PHP scripts and CSS pages.

And why yes, green is David's favorite color. How could you tell? :)
