Dark Sky is kind of an expensive app, as apps go: $3.99. Which means we have a small percentage of the market, giving it a very different growth curve from free apps. Our rate of revenue has been slowly increasing since we launched. And since our market share is so low, I don't see us running out of potential customers any time soon.

(And to answer your other question: Forecast.io makes some money, but not much. And we do have an increasingly large revenue stream in our data API)

Hi Adam, this is a fascinating post, thanks for writing it! I'm Jacob, of PressureNet, and in fact Dark Sky is the reason I'm still building weather software! You beat me to consumer-focused radar postprocessing (I was working on this using McGill's radar data in 2010, and stopped when you launched) and you did a really good job - such a good job I took a look around and started collecting barometric pressure data in a new attempt at making the best hyperlocal weather forecast! You and your team are inspiring. :)

I'd be thrilled to talk about your data API and forecast tech, especially if you're considering working with phone sensors to improve your forecast models. I'm [e-mail], have a look at http://pressurenet.io if you're interested.

Thanks for building great products and writing great posts!
