Turn a simple move-and-hold recording into stop motion automatically. You do not need to press the shutter for every frame. Keep your phone steady, reposition your clay, blocks, drawing, paper art or product, and pause briefly after each change. The app finds clear, steady moments in the continuous video and combines them into a frame-by-frame animation. Key features: • Record in the app with live hold-steady guidance • Import an existing video from Photos • Automatically find the steady frame after every change • Use on-device hand-pose detection to avoid obstructed frames when possible • Adjust frame duration, stability sensitivity and output resolution • Preserve portrait, landscape and square orientation • Loop the finished animation, save it to Photos or share it • Automatically follows the device or iOS per-app language in English or Simplified Chinese Privacy first: Video analysis, hand detection and animation rendering happen entirely on your device. No account is required. Videos are not uploaded, and the app contains no advertising or tracking SDKs. Great for clay animation, building blocks, paper art, drawing progress, product showcases, classroom demonstrations and any frame-by-frame creation.
