GainFrame: Progress Photos

Track your physique progress with AI-powered photo analysis.
Import your gym photos, organize them by pose, compare changes over time, and get estimated body composition insights from your selfies.
AI body analysis from a photo
Tap any photo to get an AI-generated physique score, estimated body fat percentage, BMI, FFMI, lean mass estimates, and 12 muscle group scores. GainFrame also provides macro targets, training recommendations, and a shareable report card. Benchmarks adjust based on your gender.
More accurate body fat estimates with multiple angles
Have multiple photos from the same day? GainFrame combines them with Apple Health data to generate a Precision Body Fat estimate that is more reliable than using a single photo alone.
See projected future progress
Choose a pose and a timeline of 3, 6, or 12 months. GainFrame analyzes your current photos and generates a projected future physique image with predicted stats, progress charts, and goal-based recommendations.
Import your photo library and let AI organize it
Import your gym photos and let GainFrame classify them by pose, including front, back, and side views. The app automatically builds your physique timeline, even across large photo libraries.
Compare progress with precision
Use side-by-side comparison or a swipe slider to evaluate changes over time. Auto body alignment helps match poses across photos, and overlays display stats like weight, body fat percentage, and AI scores directly on your images. Smart Filters help surface comparisons like Most Improved, Peak Physique, Best vs. Worst, and Largest Body Fat Change.
Deep Dive photo comparisons
Select two photos to get a detailed breakdown of what changed, including body fat, weight, FFMI, and individual muscle group improvements. Export a shareable comparison card with your results.

Important
GainFrame is a fitness tracking tool and not a medical device. AI-generated estimates, including body fat percentage, BMI, FFMI, muscle scores, and macro recommendations, are approximations based on photo analysis and should not be used for diagnosis or treatment. Consult a qualified healthcare professional before making health or fitness decisions.
