Platform: iOS, Android; Free

If you're making a trek with a buddy through the middle of the west coast, chances are you'll get a little tired of hearing each other talk after being stuck in a hot car for hours. Luckily, Netflix's app for the iPhone and Android lets you play movies on the go. Since you'll probably switch off driving responsibilities every so often, whoever is in the passenger's seat can control what movie goes on. We suggest getting a mounting kit to dock the phone on the car's dashboard to make it that much easier and carefree.
