The work flow: Upon opening the app you must select a GIF to edit. This can be done by accessing the user's camera roll, selecting a Trending Gif, searching for a GIF on the web, or creating a new GIF from the camera. Once selected, the user can choose a crop setting and adjust the GIF to fit within the crop how they'd like. The user can also choose to save the original GIF from this screen (in case they don't want to edit it). Next they can select any option from the menu: Trim, Speed adjustment, Background color, Music, adding Text, Filters, or adjustments (Like blur, contrast, exposure, etc). Then they can save it as Gif or video and share it to their favorite social networks (instagram being the most popular to share to by far).
I want people using it to know two things from the screenshots: it's the best all-on-one Gif app on the App Store (it's a gif finder, gif downloader, gif saver, gif editor, converts gifs to videos, etc), and that GifShare HD can help bring a GIF to the next level. "Make your GIFs Instagram worthy" is something you could use or if you have something better go for it.
