This app has multiple tools that you can display on your projected screen, everything from timers, counters, selectors, etc. There are old and new versions. Some people are using some of the backgrounds for their Bitmoji Classroom Scenes
tool that allows for quickly and easily designing posters, signs, fliers and more, allowing for a variety of customizations with backgrounds, clipart, and text, while also allowing users to upload and use their own pictures. My own high school kids have used it to complete one page posters referred to as visual book reports. Their end products were printed for display purposes in the library, and used for visuals for book-talks done by both the librarians and the students. We even use them in digital frames that loop through pictures at our circulation desk, and students have responded to the "book-reports" created in Poster My Wall by checking out those titles.
The site does not require an account though that is an option, and those opting to use the free version can create professional looking posters and download for printing in minutes. My school secretary was so impressed with the site she has even used it to create fliers for events and activities at school. The site is easy enough for even elementary school students. Like Wordle, my collaborating teachers are finding some very interesting uses for Poster My Wall. Cons? It is not a replacement to Glogster by any means, but a poster app none the less.

More and more, I'm appreciating the philosophy that instead of thinking you need an app for everything, concentrate on a few that are very utilitarian, and learn to use them well!
