Users create a Plotagraph by selecting or taking a photo, creating an animation track to indicate the direction of movement, and masking areas of the image they don't want to animate. It's then possible to adjust the animation speed and save the final result to the Camera Roll or share it as a video, GIF, or animated PNG using custom presets.
The editing interface features a range of tools for manipulating images, including an animation tool, selection tool, instant playback, mask, eraser, crop presets, anchor points, pinch zoom, Apple Pencil pressure sensitivity, real-time animation speed control, and multiple export options.
To get the app from the App Store, first download the free Apple Store app [Direct Link]. Then simply open the app, and the Plotagraph+ offer can be found further down in the Discover section on the main store screen. The offer looks like it's working for users in the U.S. and U.K. at the time of writing. Apple has extended its redeem codes to other countries in the past, so it's still worth checking for the offer if you're based elsewhere – let us know in the comments below if you have any success. Offer ends January 15, 2018.
