Meet Otomos, an iPhone case that can cure your childs need to constantly be on their phones! It's a fixed case that cannot be removed without a special tool (that you keep hidden) and it pairs with an app that can allow parents to limit daily usage. If they exceed the limit the phone goes into sleep mode. It even has a motion detector built in so you can't walk and text. The company plans to charge around $5 a month for a two-year contract.
