GreenGoose makes doing everyday things more playful with tiny wireless sensors that automatically measure what you do. They're ultra-low-cost stickers with a circuit inside and simply stick on to things like water bottles, pet leashes, toothbrushes, toys, pill bottles, toilet seats, and lots more. They're smart. They wirelessly communicate with all kinds of apps on your mobile phone to make what we do in the real-world more fun.
