Would you be a part of a crowdsourced environmental warning system?

Picture the scene: you’re watching the kids play in the local park when, suddenly, your smartphone goes nuts. The sensor that you’re wearing on your belt loop, along with several other sensors in the area, have noticed an increase of gamma radiation.Thankfully, you’re able to gather up your children and race back to the car before anyone suffers an uncomfortable dose. If that all sounds like the sort of thing you’d be interested in, then you should probably check out Scarab.

That sounds like a dramatic scene from a movie about a dystopian future, not a pitch for a tech gadget I’d want to own.
