Urban Canary

It may sound silly if you don't have trouble breathing or dont live in a polluted city, but for kids who are sensitive this little friend could alert them and their parents before there's a real breathing emergency.

It's like a tamagotchi that helps kids (and their parents) know when they're breathing bad air! They're incentivized to keep their little Canary healthy over time as well by staying in clean areas with map reports.

My big complaint is that there really should be some kind of keychain or wristwatch feature for kids, because what kid not going to immediately loose this thing!?
