As neither a designer nor a developer, David is a bit of an anomaly as the founder and sole employee of Contrast (née App Cubby). From accounting and marketing to art directing and QA testing, David does whatever it takes to build the apps he wants to use. He guides the development process in a way similar to how a producer collaborates with musicians to create an album. That’s not a coincidence. Before building software, David was an audio engineer and spent years in a recording studio.David has been building apps for the iPhone since day one. His first app, Trip Cubby, launched in August 2008, and he and a talented crew of collaborators have been building and iterating on apps ever since. David also writes and speaks about app development and life in the App Store.Press quotes:https://www.buzzfeednews.com/article/nicolenguyen/how-apps-take-your-data-and-sell-it-without-you-evenhttps://techcrunch.com/2019/06/12/nfc-gets-a-lot-more-powerful-in-ios-13/https://www.reuters.com/article/us-apple-appstore-idUSKCN0YV05Vhttp://on.wsj.com/14mmQkLhttp://www.nytimes.com/2011/12/19/technology/app-makers-face-holiday-cutoff-for-apple-store.htmlDavid’s apps have been downloaded by millions of App Store shoppers and have been featured by Apple and just about every tech and lifestyle site, including MacStories, NY Times, CNN, The Wall Street Journal, Wired, GQ, CNET, TechCrunch, Mashable, Macworld, Lifehacker, The Verge, MacRumors, iMore, 9to5Mac, TUAW, Daring Fireball, and more.https://techcrunch.com/2018/12/21/launch-center-pro-now-lets-you-tap-stickers-to-launch-tasks-on-your-iphone/https://www.theverge.com/2018/11/16/18098454/weather-up-atlas-calendar-event-forecast-pricehttp://www.wired.com/gadgetlab/2012/01/launch-center-automates-iphone-apps-using-notification-center/Appearance on CNBC: http://video.cnbc.com/gallery/?video=1739584420
