Have an iPhone? Have a Chromecast? Google recently released a full SDK that allows developers on any platform to create apps that plug into the Chromecast, which connects to any TV with a free HDMI port. Photocast is a simple app that allows you to display photos from your iPhone to any TV with a connected Chromecast. The premise is simple, the app is simple, and guess what — it works wonderfully. This is one of the first Chromecast apps I’ve seen on iOS, and I hope to see plenty more — maybe enough to make the Chromecast a cheaper replacement for the Apple TV if you need AirPlay-like functionality.
