Convert first month sales

So 100000 people <i>need</i> a unit converter on their phone? Seriously? I "need" one perhaps once a year, and then I just use Google (which would be available on an iPhone, too). (Need as in "hmm, gee, I wonder what x is in y", not as in "oh my god, I need to know this ASAP!!!").<p>I think there is another story hidden there - taptaptap has become so famous that people just buy whatever they put out there. Good for them, but hardly something to draw parallels from.

I think this is the first time I've understood some of the path to profitability for the iPhone App Store. It's not about making a great app and keeping it up forever. It's about having a hit, milking it for all it's got, then moving on to another app. Even if your app barely took off at all.<p>For another example, look at Tapulous. They started off with a bunch of small apps, and one of them, Tap Tap Revolution, took off. They've turned that into quite an app with numerous versions. Note that it's not just updates to the app but a bunch of more limited, artist/genre-focused apps. This kind of stuff is the key.

I agree with you Tichy, it often seems hard to believe that what people spend their money on, but the numbers are nothing to scoff at. I'd be interested to know if the sales numbers for a hit and run product cycle are linear or asymptotic, as in, will they get $130k, and then $110k out of it in months 2 and 3, or will the falloff be much sharper, say $100k, $70k, $20k etc etc? It seems like if revenue diminishes rapidly, it's an absolutely brutal and cutthroat market, not one that I'd like to be in. However, if marketing efforts can keep the app riding high for a few months, the proposition looks a lot sweeter.<p>Regardless of the sales falloff, nice work guys, and congratulations.

Good article, I remember seeing these guys awhile back with their first couple apps. They definitely have it down, useful tools with user friendly designs.
