Features
Read full description

One Second Later captures two photos a second apart — 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. Save, morph, export, or retake FREE FEATURES • One-tap dual capture with a clear countdown • Front and back camera • Side-by-side compare with before/after labels • Morph blend between the two frames • In-app library with albums, favorites, captions, and search • Import two photos from the system Photos picker • Pair playback with Reduce Motion support • Home Screen Last Pair widget and “Capture one second later” Shortcuts / Control Center control • Core capture stays free — no account required PREMIUM (MONTHLY OR YEARLY) • GIF and MP4 export • Export without watermark • Extra delays (3s, 5s) and Time Lapse / Burst / Grid modes • Gold theme • Optional on-device caption suggestions where Apple Intelligence is available (you review before saving; photos are not sent to a cloud AI) Privacy-first: captures and library stay on your device. Selected Photos import uses the system picker. Optional caption help uses on-device Apple Intelligence when available — never inspects your photos as model input.
