In addition of being an amazing app for research you will also get the chance to look at the magnetic field of the world around you.
Electromagnetism... we've definitely heard about it. Visible light, X-Rays, radio frequencies, and yes, Earth's magnetic field are all different ranges of the same scale. We know it changes based on our possition on the planet, but there is so much more that remains to be seen. We are constanlty pushing the limits of what we know and with this project we want to map as many cities, countries, places as possible!
We are looking at how electronic devices affect their surroundings and doing so by looking at the environmental sensors on the phone (acceleration, gyration, compass, etc...) We've done our best to protect everything you share with us and we will show you the results of your contributions. There is a complete information sheet inside if you are curious. Give it a try! It is fun for you and incredibly useful for us.
