Meet Tinitell: a wearable device for kids that gives parents peace of mind. It allows kids to move freely while parents can keep track of their position using a built-in GPS system. This durable device is water resistant and can survive exposure to sand. It has voice recognition to make it easier for the wearer to use. The calls can be forwarded from your smartphone with the Tinitell app.
Once you get one of these, you need to add your SIM card and download the companion iOS/Android app. The device has voice recognition software, so you can make a call by pushing the appropriate button and speaking to your Tinitell. The device can also receive calls. Users can define who can call and which numbers Tinitell should answer automatically.
Tinitell is developer friendly too. The device sounds very promising, but you will need to pay for your SIM card and service subscription. Like it? Support it on Kickstarter.
