iOS: Apple's new Live Photos shooting mode is neat and all, but it takes up a ton of space and is a proprietary format that's useless outside of an iPhone. Lean is a simple app that will convert those photos to normal photos to save space.
When you launch Lean, you'll see all your Live Photos. Just select the ones you want to convert, and Lean does the rest. It deletes the old Live Photo in the process, so make sure you really want to get rid of it before you run it.
