Constant Change

Constant Change helps you document slow visual changes with photos taken from the same point of view over days, months, or years. Start a recorded change with a reference photo, then use that image as a transparent ghost or edge guide in the camera viewfinder. Each new photo can be aligned to the reference, so the final sequence feels steady even when the subject changes slowly over time. Use it for body progress, pregnancy, growing children, plants, hair or beard growth, construction projects, restoration work, or any long-running process that deserves a careful visual record. Features: - Track multiple recorded changes at once - Use a reference photo as a ghost or edge overlay while capturing - Add notes, date, place, and measurement metadata to each photo - Read body weight from HealthKit when you choose - Use delayed capture for self-portraits and tripod shots - Fine-tune alignment manually with drag, pinch, and rotation gestures - Preview your sequence as a video - Export MP4 videos with optional title cards and subtitles - Export and import recorded changes as archive files
