With the influx of surveillance technology on the market it may seem strange that the means to track your children has not been addressed more widely. Tags and collars are wholly inappropriate, and the age to which a child could be deemed mature enough to carry a phone is always a sticking point. Now with Tinitell an answer has been realised in the form of a small mobile phone disguised in a bracelet. Like FiLip before there is no real new technology on offer here, but more an answer to the question of how to know our children are safe in as unobtrusive a way possible. The phone is the idea of entrepreneur Mats Horn and was designed by Stockholm based studio Newd. The wrist-phone has been designed to be tested by the playground and is water resistant as well as able to cope with the rigours of the sand pit. To keep things simple enough, make a call the wearer only needs to push a button and say the name of their desired contact. The phone works via an app in which parents can input contacts and set up its voice recognition system.  Through the app It also allows the option for parents to set the phone to automatically answer calls from certain numbers. Tinitell is expected to ship in April next year.
