According to the CDC, “from 2005-2009, there were an average of 3,533 fatal unintentional drownings (non-boating related) annually in the United States — about ten deaths per day.” That’s much too large a number, and if the iSwimband pictured above can help bring it down even just a bit, we’re all for it. This device basically alerts you when it senses that one of your children could be in danger of drowning. There are two models: one is for swimmers and is worn around the head, the other is a wristband for younger kids and those who don’t swim yet. The swimmer’s headband lets kids go in the water, but will alert you on your phone if it senses its been under water for too long. The non-swimmer’s wristband however will immediately ping you if it gets wet. This way you can step away from the pool for a couple of minutes, or read that book, without having to worry that your kid will disobey you and actually get in the water like you told him not to. It’s $99 for a set including the app, and two sensors.
