## What is DayByDay Photo Tracker?

DayByDay helps you see your progress, one photo at a time.

Whether you are tracking fitness, posture, facial changes, orthodontic progress, or any other visual transformation, DayByDay gives you a simple private place to capture, organize, compare, and share your progress over time.

Take a new photo in the app or import photos from your library. Organize each entry by category, then browse your progress in a clean timeline or gallery. When you want to see what changed, select two photos and compare them side by side or with an overlay. When your series is ready, create a time-lapse GIF to save or share.
