A camera roll stores images, but not the whole context
Your phone gallery is a useful starting point, but photos can become difficult to find or compare when dates, angles, lighting, and views are mixed together. Routine changes, product notes, and lifestyle context usually live somewhere else.
A tracker makes the photo routine repeatable
A photo-first tracker can keep the date, view, and check-in context beside each upload. Using the same front or side view, distance, and light makes a before-and-after comparison more useful than choosing two convenient but different photos.
Use a camera roll when simple storage is enough
If you only need occasional photos and already have a reliable naming or album system, your camera roll may be all you need. A dedicated tracker becomes more useful when you are testing a routine, documenting a longer timeline, or returning to compare several check-ins.
Privacy and control still matter
Whether you use a gallery or a tracker, keep sensitive photos in an account and storage setup you understand. Body Progress is designed for private progress records and non-medical observations; it is not a diagnostic service or a replacement for professional care.
