If you’re a parent whose kids are old enough to own a phone, you’ll know how frustrating it can be when they choose to ignore your calls. A new Android app developed by a mother hopes to curb that silent treatment by rendering smartphones almost unusable until they are finally answered. Sharon Standifird from New York was so fed up when her teenagers began ignoring her calls and text messages that she worked with a team of app developers to create Ignore No More. Once installed on an Android device, it has the power to shut down almost all of its features until the handset’s owner gets in touch with their parents.
