Keep your physique in perspective: compare check-ins with Photo Match, follow estimated body fat and muscle trends, and explore your history with Coach.
Build a record of your physique, one check-in at a time. Corpus brings progress photos, body composition estimates and training context into a history you can return to as your body changes.
MAKE YOUR PHOTOS EASIER TO COMPARE
Capture guided check-ins and browse your front, side and back photos over time. Compare two check-ins side by side or with a slider. Photo Match checks visual consistency in pose, lighting, distance and framing, helping you spot differences in how the photos were taken before interpreting a change.
FOLLOW THE NUMBERS OVER TIME
Review estimated body fat percentage, FFMI, a composite score from 0 to 100 and ratings for eight muscle groups. See changes alongside your photos and logged weight. These are estimates for fitness tracking, not clinical measurements or medical advice. Capture conditions can affect the results.
KEEP THE STORY BEHIND YOUR PROGRESS
Explore your photo history in Backstory and revisit weekly Chapters. Trends bring your check-ins, consistency and progress into view. Set milestones for your goals and follow how you are progressing toward them.
ADD CONTEXT FROM YOUR ROUTINE
Optionally connect Apple Health to see available sleep, heart rate, activity and workout data alongside recovery and training trends. What appears depends on your permissions and the data recorded by your devices and apps. Photo check-ins work without Apple Health.
ASK YOUR AI COACH
Discuss your check-ins, muscle ratings, goals and trends with a Coach that uses your recorded context. Bring a question about your progress and explore what deserves a closer look.
Start with a baseline, return for your next check-in and build a clearer view of your progress over weeks and months.
