Google introduced Motion Stills on iOS in 2016. The app enables users to convert Live Photos into movies or GIFs applying stabilization to the video in the process. Live Photos can also be combined into moving collages.
Google has released version 2.0, which dispenses with the need to access your photo library to add Live Photos to a Motion Still. Instead, the app can now capture Live Photos and Motions Stills from within the app itself. The option to import from your photo library is still there, but having the option to shoot from within the Motion Stills app is a convenient addition. The new version also lets you delete Live Photos from your photo library with a swipe gesture and export collages you create as GIFs.
Motion Stills is available on the App Store.
