Amazon has leapt into the smartphone market with Fire Phone. Its operating system is a customized version of Android. At this point, it\u2019s expected that apps created to run on the Android OS will operate on Fire Phone. But consumers will be able to download apps onto their Fire Phones only from the Amazon App Store. \r\n\r\nShould you rush to make your app available for Fire Phone? \r\n\r\nNot necessarily. For now, the phone only offers service from AT&T, which will limit its user base. If you do, you\u2019ll want to work with developers who bring experience with the Amazon App Store, since optimizing app profiles to maximize their exposure is a somewhat different process that the steps needed to do so on Google Play.
