Really buggy.
The app is really buggy and sometimes I needed to press the buttons twice for them to work or I needed to close the app and reopen it for it to work. It did it’s job to covert the videos to live pictures. It has different aspect ratio as well if you want it in portrait or landscape. In IOS 17, it didn’t let me choose the live pictures from this app. Only the pictures that were captured by the camera works for the live Lock Screen live feature. It seems like Apple is restricting third party apps from using the live picture Lock Screen feature.
