A dad has created the app that many parents could probably use. Nick Herbert has developed ReplyASAP that forces your child to do just that, reply to your texts. It will freeze your child’s phone and even send an alarm until the receiver responds.
Unfortunately, the app is currently only available for Android devices. It’s free but you can pay to unlock other features. You can download it here: https://play.google.com/store/apps/details?id=uk.co.replyasap.alarm
