The Good: The results from Adobe Post look good and it's easy to use. The Bad: The app is free but Adobe's slightly spammy to compensate. The Bottom Line: A free-with-registration iPhone app that produces attractive text-overlay-on-image graphics for social media, Adobe Post is fun and easy to use. As part of its "storytelling" series of free standalone iOS apps, which currently consists of Adobe Voice and Adobe Slate, the company jumps into the "social graphics" (for want of a better term) market. Unlike those other apps. however, Adobe Post competes with boatloads of different ways to create artsy-looking photos-plus-type-overlay graphics -- Text on Photos and Videos, Canva, FontCandy, Wordswap, Typorama and Fontspiration, to name a handful -- for use on social media. It's currently available only for iPhone, unlike it's companion apps which are iPad only.Adobe sees a few types of users for Post: individuals who want to post prettified pithy pontifications to social media or want attractive ways to blast out "we're having a party!" with a link, and more business-oriented folks who want easy-to-generate social-media-friendly marketing graphics.Post is pretty well-designed and easy to use. It's based on the concept of what Adobe refers to as "remixing," though really that's just slapping a hip term on the themes or templates that you use as starting points for your graphics, dubbed "Posts." Terminology aside, though, Adobe used studies of the most popular Pinterest repins to choose the characteristics of its 42 initial designs, and they're attractive in a generic stock-photography way. Adobe plans to update the designs and content on a regular basis. Each theme consists of a photo and text, to which the app applies filters, typefaces and type treatments. You can choose your own image from any of multiple sources, including a search of nice public-domain photos. The app automatically crops it to a 1:1 aspect ratio, and you can pan and rotate to choose the visible area.
