You bring a good point to the table. DoodleCam is a joke app, meant for entertainment and without much ability to provide real value to a community.

However, I have built it in attempt to find popularity so that my real apps are able to gain more traction. I also build an open source barometer network called pressureNET that collects atmospheric readings from some Android phones. I have millions of barometer readings and I gain about 17,000 every day right now. I'm hoping to use the data to find new methods of short-term, local weather prediction, but the network is currently too small.

I've found that as DoodleCam rises in popularity, pressureNET gains too. It's a good method.

See https://play.google.com/store/apps/details?id=ca.cumulonimbu... for the app.
