One Second Later captures two photos a second apart β€” then shows you what changed. Tap once. The app takes a before frame, waits one second, and takes an after frame. Instantly compare them side-by-side or watch a smooth morph between the two. Perfect for kids’ expressions, pets mid-play, street energy, sports reactions, and any fleeting moment that is better as a pair than a single shot. HOW IT WORKS 1. Open the camera and frame your subject 2. Tap Capture 3. Hold still (or change!) for one second 4. See before and after instantly 5.
