In our ongoing series of interviews with developers and creators in the Apple community, I had the chance to talk with Greg Pierce, founder of Agile Tortoise. Greg makes some of our favorite iOS apps here at MacStories, namely Drafts and Terminology. Greg is also the man behind x-callback-url, an inter-app communication spec that I’ve been personally researching for the past few months. On Twitter, you can find Greg as @agiletortoise.
The interview below was conducted between May 7 and December 29, 2012.
Federico Viticci: Hey Greg! Could you introduce yourself to the readers who haven’t heard about you or haven’t tried any of your apps before?
Greg Pierce: Well, my name is Greg Pierce. I’m a family man and somewhat accidentally a professional developer living near Fort Worth, Texas. I am President of Agile Tortoise, an indie software company I founded in 2006 – where I split my time between developing my own iOS and web projects, and doing consulting.
Most of your readers would know me best for my word reference app Terminology, and for my newer apps Drafts and Phraseology. While I, sadly, am not a great writer myself, I’ve always had a great love of language and writing and I try to focus on producing simple and useful tools to writers (or anyone else using text and words) that exploit some of the interesting possibilities of the iPad and iPhone.
When I’m not working on my apps, I do Ruby on Rails development – primarily STEMscopes.com, a Texas-based science curriculum resource that serves K–12 schools. This is also an exciting project that is on the cutting edge of the move to replace traditional textbooks with online resources. Read more
