A few days ago Twonky launched their Twonky Mobile app for the Apple iPhone and for Android phones.
Here is what Twonky say about their mobile apps:
Twonky Mobile Apps
If you don’t want to crowd around a computer monitor to share your media, you certainly don’t want to be stuck gathering around your phone’s three-inch screen. Access your mobile phone’s photos, videos and music from your networked devices with our Twonky apps – available for Android™ and iPhone®.
Twonky Mobile lets your Android or iPhone become the ultimate remote control. Beam media to devices around your home. View the Android or iPhone page to find out more about each version.
TwonkyServer Mobile is a free version of the award-winning TwonkyServer™ for your Android phone, letting you share music, photos and videos from your phone to your connected TV, game console or other devices. It works with most UPnP™ and DLNA®-certified devices.
Twonky Mobile lets your iPhone become the ultimate remote control. Find media on your network, such as the music, photos and videos stored on your computer, and play them on your phone or beam them to your TV or other network-connected media player (such as DLNA-certified devices or Xbox 360). Select your media library and player, then queue your media for instant playback. You can also access photos on your iPhone from most networked-connected screens, or beam them to supported devices.
The app costs $2.99 in the US AppStore and £1.79 in the UK AppStore.
