Trace is a quiet photo journal for the things that change slowly.
Take a photo today. See it as a translucent overlay tomorrow. Capture the same shot, the same angle, the same moment — across days, weeks, months. Then watch your timeline unfold.
Perfect for tracking diet progress, plant growth, room transformations, or anything else worth remembering in slow motion.
KEY FEATURES
— Reference Overlay Camera
See your previous photo through the live camera view. Adjust opacity with a smooth slider. Match the angle, framing, and moment perfectly every time.
— Two Compare Modes
Stack mode shows photos side by side, top and bottom. Slider mode lets you drag a divider to reveal change with a wave-style boundary. Pinch to zoom into any detail.
— Folders & Projects
Organize your timelines into folders. Create projects for plants, friends, fitness, or anything you want to track. Set custom cover photos for each.
— Photo Library Import
Bring in photos you already have. EXIF dates are automatically preserved so your timeline starts from the moment the original shot was taken.
— Beautiful Export
Save your timeline as a slideshow album in Photos for easy playback, or export as a single vertical collage to share. Send to anyone via the share sheet.
— Editorial Dark Theme
Lora serif headlines, Inter sans interface, and a coral accent on a deep charcoal background. Designed to feel like a quiet space for reflection.
— Privacy First
Every photo and project stays on your device. No accounts, no cloud sync, no analytics, no ads. Your moments are yours alone.
— Two Languages
English and Korean (한국어), with daily-reset onboarding.
