December 28th is the Spanish equivalent to April Fool’s day. That is why I had to read twice the news that iFart Mobile (see video) was the best selling application in App Store during the holidays (iTunes Link).
All I knew was that a lot of people would be getting iPhones and iPod Touch MP3 players on Christmas Day. Christmas came a day early for us. On 12/24, my jaw hit the floor when I checked my stats. We sold 19520 units, providing $13364 in net income after Apple takes their cut. I now knew that Christmas Day would be bigger than I would have imagined. I made sure I was sitting down before I checked my day-after-Christmas stats. It was a good thing. On Christmas Day, 38,927 people purchased iFart Mobile. Thirty-eight thousand nine-hundred and twenty seven. Wow. Thats $27,249 net. Again I say, wow.
Apple App Store and Android App Market are bringing more spotlight than ever to the applications for mobile handsets. Though a vast number of applications already exist for Windows Mobile, Blackberry or Symbian, developers are working hard to write the next killer app on the iPhone and Android platform.
What criteria should guide developers when designing the next mobile killer app? Here are some suggestions of the ingredients a mobile killer app better have:
Useful. There must be a clear value to the user. What problem does the app solve? How is people impacted? Who/how many are impacted?
Usability. User experience first. Simple, fast and engaging.
Immediacy. Must be useful here and now, where and when I need it.
Context-Aware. Intelligent enough to know where are you, with whom, what are you doing (on a call, or a meeting) , your weather, and have the app behave accordingly.
Viral / Social. Know your community and your friends.
Coolness. Beautiful, elegant and enjoyable.
To these criteria, add this principle: “The innovation […] is not that they let us do something new, but that they allow us to do what we already do better, more often, in more places and more quickly.” -Joshua Porter
