Here's one way to curb phone addiction.

A Japanese company has created an iPhone case to help parents stop their kids from becoming too addicted to their phones.

The case, called the Otomos, is fixed to the phone and cannot be removed without a special screw.

Otomos pairs up with an app that allows parents to limit the child's daily phone usage. If the child exceeds their daily limit, the phone will automatically enter sleep mode.

Motion detectors built into the case are also able to deactivate the phone automatically while the child is walking.

Otomos, which was created by Momo Ltd, can also send automatic messages to parents' phones if it senses that a significant physical shock, such as an accident, has taken place.

"We have developed the product after hearing many views and concerns of parents who have children using smartphones," Masato Otsu, president of Momo Ltd, told Kyodo news agency.

"All you have to do is just attach the case, so it is very easy to use."
The smartphone case had earlier raised some $8,000 on Japanese crowdfunding platform Makuake.

The company is expected to charge around $5 a month for a two-year contract that includes the case.

As of now, the case seems to be compatible with only iPhones, so if you're an Android family, you'll just have to keep your kids away from their phones some other way.
