Morph
Read full descriptionHide full description
You can't see your body change in the mirror. It happens too slowly — a little every week, invisible day to day. Morph shows you the change that's actually happening. Take the same photo over time and Morph lines them up, plays them back, and reveals the progress you'd otherwise miss. HOW IT WORKS A "Morph" is one pose you repeat — front, side, back, a bicep flex. Each time you shoot it, Morph adds to the sequence and builds your transformation automatically. GHOST OVERLAY CAMERA Your last photo appears faintly over the camera, so every shot lines up in the same pose, framing, and distance. Consistent photos make the difference obvious. BEFORE / AFTER SLIDER Drag between any two days and watch the change happen under your finger. This is the moment most people don't expect. TIMELAPSE VIDEOS Turn weeks of photos into a few seconds of transformation you can save and share. STAY CONSISTENT Set a cadence for each pose — daily, weekly, or your own rhythm — and get a quiet nudge when your next photo is due. No pressure, just a gentle reminder to keep going. PRIVATE BY DESIGN Every photo stays on your device. Nothing is uploaded, nothing is shared, no account required. Lock any Morph behind Face ID. Morph Pro unlocks the ghost camera, slider, timelapses, export, and unlimited Morphs. Start today. Your Day 1 is the one everything else gets compared to. Morph Pro unlocks all features with an auto-renewable subscription: • Morph Pro — Monthly: $12.99 per month • Morph Pro — Annual: $29.99 per year Payment will be charged to your Apple ID account at confirmation of purchase. Your subscription automatically renews unless it is canceled at least 24 hours before the end of the current period. Your account will be charged for renewal within 24 hours prior to the end of the current period. You can manage or cancel your subscription anytime in your App Store account settings.
