  4. View records and photos

    Open a date in History to see the day's exercises, values, and images. Photos from the same angle make progress easier to compare.

  5. Manage storage

    In “More” → Photos, check storage and select unwanted images. In-app images are resized, so keep any originals you need separately.

Case: morning measurements and weekend photos

Save morning bodyweight measurements and take a photo from the same angle at the weekend. Review them alongside that week's training. RENMA does not automatically calculate body fat or muscle growth from photos.

Back up before changing phones

To move bodyweight and photos too, use a restore backup. Its contents differ from an ordinary CSV or Bridge migration format. If missing photos are reported, check which ones and whether you still have the originals. Basic bodyweight and photo features are available with Free.

The screens use sample records to explain the controls.
