We’ve teamed up with iMediaShare, our latest AppAdvice Daily podcast sponsor, in order to bring you a double-dose of giveaway goodness. Not only has the team at iMediaShare made their premium media streaming app available for free today only, but they also want to reward you for your valuable feedback with $50 Amazon gift cards!

The iMediaShare app is a powerful yet easy to use media streaming application for iPhone and iPad. It features the best free selection of streaming content, from sources like Showtime, PBS, CNN, TED, NASA, and Discovery Channel, and allows you to watch it on your iDevice or on your home television. You’re also able to stream content from your favorite online sources, like YouTube and Vimeo, and all of the photos, videos, and music in your iDevice’s library.

Supported devices appear like magic!

Streaming content from iMediaShare to your television couldn’t possibly be easier. Just tap to select your content, whether it’s streaming from an online source or from your library, and then tap the screen icon in the top right corner. All supported devices will automatically populate the list, and you can immediately begin streaming to anyone of them  with another tap.

Supported devices include Wi-Fi connected televisions from the likes of Samsung, LG, Sony, Panasonic, and more. The easiest way to identify a compatible television is to look for a DLNA or AllShare logo. If it has one, you’re in luck. The iMediaShare app will also connect with your Xbox 360, PlayStation 3, Apple TV, Sony Blu-ray player, Mac or PC, and basically any other DLNA, UPnP, or AirPlay compliant device.

The iMediaShare app is normally available for $4.99, but today only you can download it free of charge. All we ask in return is that you provide the team with some feedback via the comments section below in order to help them make improvements to iMediaShare. The three most constructive and useful comments will receive $50 Amazon gift cards!

All entries must be received before Feb. 17 at 11:59 p.m. PST. Only one entry per person is allowed, and are limited to those where Amazon’s services are available. Remember to also check your junk email box when the giveaway is over!
