I've only recently learned about an app called Adobe Post. It's an iPhone app, but it works on the iPad too. Using Adobe Post, you can quickly create beautiful graphics that are meant to be posted to social media. Each image is formatted so it will fit perfectly into any social media application, but you aren't limited to that use. It would be a great tool to create an introduction graphic for a video or slide show. You could also use it as a signature graphic for e-mails or use an Adobe Post graphic in conjunction with other graphics in a collage.
Adobe Post is a free app, but you will need to create an Adobe ID to use it. If you are already using Adobe Voice or Adobe Slate you can use the same ID for this account as well. That's one of the things I like about Adobe - it saves all of your work under your ID so you don't have to worry about losing any of your pictures if you happen to share a device with someone else.
To create a graphic there are four simple steps:
1. Click the + sign and select a graphic (yours or theirs - and they have some high quality graphics).
2. Select a Palette.
3. Enter Text.
Inside the app, you can change almost anything - so you have a lot of flexibility to create some amazing graphics.
