Owners of the Chromecast streaming dongle by Google know there are a few must have apps. YouTube(obvious one), NetFlix, Google Play Music, and HBO Go. There are more apps that are capable of streaming to the dongle, and you can find the entire list at chromecast.com/apps. However, there are a lot more apps that can stream to the Chromecast that are just harder to find since they are third party apps and not listed on the site. That will soon be changing as Google is getting ready to open up the application process for third party apps to make their way to the site.
Google has sent out emails notifying developers of some great news for their casting capable apps. They will now be able to start the application process that could result with their app being featured on the official Chromecast site. This is a big opportunity for third party developers to get their apps recognized and possibly downloaded by millions more people. In the email, Google talks about how they "want to make it easier for users to find great Google Cast Ready apps." Which may have been one of the biggest issues for both users and developers-discoverability.
For the most part, users would stick to the apps listed on the official Google Cast site. It's where you can find apps that you know will work with your Chromecast. However, there is the application process that each developer needs to go through first before they can be featured on the site. "In order to be listed on the Chromecast site it is very important that you provide us with details about your apps." For most developers, the application process is nothing new. Google is asking for basic information that is required for every app. Categories, websites, name and availability are among the set of questions that must be answered to apply. Developers will also need to put their casting app in a category such as music, movies and tv etc. The best part for developers is the new terms and conditions that are specific to the casting apps.
Once developers get through the entire application process, they will be prompted to accept updated terms and conditions. These new terms and conditions give Google the "right to use the assets [developers] provide to promote [their] app's integration with Chromecast." Having an app promoted and available officially from Google will give users the confidence in the app that just posting it in the PlayStore can't achieve. Though the application process is open now, it is unclear when Google plans on opening the third party apps on the site.
Google I/O is a developers conference and just around the corner. So it is highly likely that we'll be seeing the launch of the new Chromecast site during the conference. However, there is no official word from Google. We will just have to wait to find out how many casting capable apps have been hiding in the PlayStore.
