The next time you're out drinking, don't rely on your equally inebriated friends to stop you from drunk dialing your ex or the girl from the gym who shot you down last week. Instead of making bad decisions based on what that shot of Patrone is telling you to do, let the Bad Decision Blocker (BDB) help you make a good decision tonight.

This iPhone app is quite possibly one of the most useful apps you can ever have and one of the easiest to use; Once you open the app, select any name from your list of contacts that you want to block. Then, use the slider to choose the duration of the block, which can vary depending on just how long of a night you're going to be having.

If you think you'll be pulling an all-nighter, make sure to choose a time frame that will get you through the morning. And, if just one night doesn't seem safe enough, you can choose to block communication via your iPhone with the person for up to a week. Finalize the block by clicking on Yes and a screen will appear showing you who you've blocked and for how long. Once the time frame has expired, you can go back into your phone and unblock your contact. The Bad Decision Blocker is available now at iTunes.
