If you are a parent who has sent a dozen messages to your child without a response, a new app could be the perfect solution. Nick Herbert designed the app ReplyASAP, which will lock your child's cellphone until they respond to your text. It will make a sound alerting them you've texted, even if the phone is in silent mode.Herbert said it can also be used for elderly family members.
For now, there is no iOS version for Apple devices, but anyone on an Android device can find it in the Google Play store.
