There is already a huge market for modern, high end mobile phones that passively record the environment constantly, in order to wake up and respond when their user says "Hey Siri" / "Ok Google" / "Hey Cortana". Users tend to carry those with them everywhere. I see that your company plans to "build[] an open platform for atmospheric data collection using smartphone sensors". It looks like you support Apple and advertise their products on your company's website: https://www.pressurenet.io/blog/iphone-6-has-barometer/ https://www.pressurenet.io/blog/iphone-6-has-barometer/ "We’re excited to start including iPhones in our study of the atmosphere!" If you believe that "every purchase[] is a signal", then what signal are you sending about Apple iPhones? I have not researched it in detail, but it seems like you're relying on data collection from large networks of smartphones in order to put together accurate weather forecasts. That's cool! But I find it hard to reconcile with the view that smartphone data collection (from people who volunteer to participate, or who use a product that has a collection feature) is invasive.
