Foursquare seems to rely heavily on WebKit. Why?

Though Foursquare definitely has a unique visual design, Apple inspired some of the smaller details, didn’t it?

Chapter 6 Q&A: Exit Strategy NYC

Chapter 6 Q&A: Exit Strategy NYC

You had an app idea that demanded a big time investment, even before programming began. How did you know it’d be worth it?

You had an app idea that demanded a big time investment, even before programming began. How did you know it’d be worth it?

New York is a big city, but how did you know there'd be a market to sell to?

87

Why is this idea best suited for the iPhone?

What about the 10MB download limit over 3G?

Version 1.0 didn’t cover every subway station in New York. Is it worth pursuing the “long-tail” customer who wants every corner of a map documented?

Did you consider making the app standalone?

118

Were you looking to imitate the desktop experience?

Chapter 13 Upgrading

Chapter 13 Upgrading

One question many of the developers in this book have pondered: do I charge for my upgrade? Do I charge for my app at all?

One question many of the developers in this book have pondered: do I charge for my upgrade? Do I charge for my app at all?

What about ad-supported apps like your free version of Instapaper?

184

Are free upgrades a good idea? Or should you make users pay again? Let’s use Exit Strategy NYC, featured in Chapter 6, as an example.

Loren Brichter, who developed Tweetie 2 and is featured in Chapter 1, decided not to do a free upgrade. Yet Tweetie 2 still shot to the top of Apple’s “top grossing list” when it went on sale. How is Tweetie 2 different from Exit Strategy NYC?

What happens when the scope of your app changes with a second version, as with Exit Strategy NYC? Should Jonathan have changed the name and risked losing the benefit of SEO in the App Store, in the hopes of having a name that describes the app better?

Does the name of an app need to convey exactly what the app does?

186

Do you think buyers have price “benchmarks” that developers should attend to?

186

So reviews are skewed negatively in the App Store?

187

What is the case to be made for apps over $5.00?
