Interview with Corey Johnson of NueroSnack


interview cory johnson of nuerosnackAppCraver recently spoke with Corey Johnson, the developer of NeuroSnack, about the experience of developing apps for the iPhone and iPod touch.

1. When did you start developing apps for the iPhone?

Cory: April 2008

2. What was the inspiration behind your app?

Cory: I read an article in wired magazine about n-back tests. These are supposed to increase your overall fluid intelligence, as opposed to other brain training games which just increase your aptitude for a very specific task. Since my wife was about to start the California Bar Exam, I though training with n-back tests might give her an edge. So I downloaded the journal article on study and started work on the iPhone version of the test.

3. How did you settle on your price point for the app?

Cory: There are PC versions of n-back tests that sell for $80, so I knew there was a market for this kind of app. But I also wanted to keep the app under $5, so I settled with $3.99

4. Roughly how many units have you sold?

Cory: It’s only been available for a month now, so I’d rather not say until I get more data in.

5. How did you like the developer tools provided in the iPhone SDK? Is there anything missing?

Cory: The debugging, simulator and building tools are great. I also love the built in documentation for the Apple frameworks. My one wish for the SDK would be for it to support a dynamic language with an interactive console (I’m not a big fan of Objective-C)

6. Is your company privately owned? Venture backed?

Cory: It’s just me!

7. What are some of the other iPhone apps that you like?

Cory: The third party apps I use the most are NYTimes, NetNewsWire and Twinkle. On my commute to work (on the bus) these apps usually keep from getting bored. I also am minorly addicted to MotoChaser, but it’s harder to play on the bus since it uses the phones accelerometer to drive the bike.

8. What kind of features should Apple implement in future versions of the iPhone / SDK?

Cory: One thing I would like is more information about our app while it is in the review processes. Since it takes anywhere from 1 to 2 weeks to get an app accepted, knowing where in that process your app is would be very handy. Another would be an in-app mapping API. Now you either have to use the external Google map app, which will exit your app; or use a web-based api, which tend to be very slow.

9. What’s the development cycle for iPhone apps like?

Cory: It depends on how much time I have to develop. NeuroSnack took around two months for me to finish, but most of that time I wasn’t actively working on the app. It was only in the last two weeks that I really spent a good deal of time working on the app.

10. Are you working on any other apps that you will be releasing soon?

Cory: I’ve got two other apps I’m working on now. One is a drinking game and I’ll keep the other one a secret for now. Hopefully both will be sent off to the app store for review next week!

    What is the best way to get into developing iPhone apps? I know its a broad question but can anyone give me a step by step?

  • DexMex77892

    Yes i agree Twinkle is a pretty good app too

    If you are interested in NeuroSnack, have a look at IQ boost. IQ boost offers extensive graphs/stats and a more accurate implementation of the Dual N-Back task. IQ boost was the first Dual N-Back implementation on the iPhone and it's more refined.

    Note: I wrote IQ boost so I am obviously biased, but you owe it to your self to compare.
