About Me

Hi. I'm Pete Callaway, a software engineer at Apple.

Qwiki automatically turns pictures and videos from events you’ve captured on your iPhone into brief, beautiful movies to share. We pick the best moments and pacing—then add transitions and a soundtrack.

Users can rearrange, add, or remove pictures & videos, customize captions, select a filter, and edit the pre-selected soundtrack with a favorite song from their music library.

Qwiki was selected as Editor's Choice on the App Store and was acquired by Yahoo in July 2013.


Simple, intuitive and elegant. Summly redefines news for the mobile world with algorithmically generated summaries from hundreds of sources. Innovative gestures, animations and great summaries make reading the news fun: easy to use, easy to scan, easy to read, clear and concise.

Summly was featured in the App Store's Best Of 2012 and was acquired by Yahoo in March 2013.

It presents news in digestible chunks that are more detailed than tweets, with a beautifully-designed, gesture controlled interface tailored for a mobile screen.

Hi Mom

Hi Mom is a Y Combinator backed mobile app, that lets you create postcards from pictures you've taken on your phone. You can then send them as beautiful emails or physical postcards to your parents - or anyone else you'd like to keep in touch with on a regular basis.

HiMom does what its name says: it is about creating and sending postcards, and building up a relationship specifically around one or two particular people.
