We've previously mentioned that there are some new apps to block texting or even calls while driving. Here are four of the popular text-blocking applications ("apps") available for your cell phone:
1. Textblocker will turn off your cell phone completely while in the car, making it unable to send or receive texts, e-mails, or calls. It can tell a parent or boss that your phone is turned off.
2. Izes Up also turns off the phone and disables its functions.
3. Zoom Safer will block text messages and phone calls, and send an auto reply message that you're driving if someone tries to contact you. This service has a one-time fee (rather than a monthly fee).
4. Cell Safety prevents you from texting or surfing the web while driving, but you can still make phone calls.
Each of the apps uses a Global Positioning System (GPS) to detect when a cell phone is in motion and can turn off or block a signals to a caller when they are in a car. Unfortunately, they only work on "smart phones," such as Blackberries, iPhones and Droid phones. Eventually, the technology should be available on all phones.
