The newest app from Cloud.TV is out in preview form, and it's already looking quite promising. You might know Cloud.TV from the wildly popular HD Widgets app. This time the dev is tackling dock apps with DayFrame. We've seen various photo frame and dock apps, but the way DayFrame integrates Google voice input is something new.
The app can display photo streams from Tumblr, Instagram, Facebook, Flickr, and Twitter. You will have to add your social accounts if you want personal pics to show up, but a few popular public streams are included at startup so you can get a feel for the app. The slideshow view slowly zooms or pans around a picture for a few seconds before fading gently to the next one. A sidebar to the right has the time, date, alarms, and battery level. There is also a large voice command button that pulls up the Google voice search interface. The developer recommends Android 4.1 because it has better voice controls, but you can still use DayFrame on older phones.
If you want to comment on a friend's picture, DayFrame will automatically pull up the Google voice to text feature so you don't have to take your phone off the dock. There are a lot of cool things going on here, and this is just the preview app. The full version will be out in a few months, and you can enjoy this one for free until then.
