Why context is everything
A photo isolated in your camera roll only tells you what you looked like. It's a single data point.
When you open a photo in GainFrame, you see a complete snapshot of your fitness journey on that exact day:
Body Composition
GainFrame's AI calculates your estimated body fat %, BMI, FFMI, and scores 12 individual muscle groups.
Weight Scaling
GainFrame pulls your daily weigh-in via Apple Health and pins it to the photo.
The Hevy Workout
Every exercise, set, and rep from that day, plus your total aggregated volume.
When you put all of this together, you can finally answer the question: "Did this program actually work?"
Comparing photos with workout context
The real magic of the Hevy integration happens when you compare two photos months apart.
Instead of just eyeballing whether your shoulders look wider, GainFrame's AI comparison tells you exactly how much your shoulder muscles improved visually (e.g., "Developing → Strong"). And right below that result, you can see your Hevy logs.
You might notice that your lateral raise volume doubled over those six months. Or that you switched from dumbbell to barbell overhead press. You're no longer guessing about what works — you have the workout data and the visual proof sitting side-by-side.
The missing piece of your fitness stack
You already track your macros. You already use Hevy to track your lifts. It's time to stop treating your progress photos like a messy folder of random selfies.
GainFrame takes the precision you apply to your training and applies it to your physique tracking. Connect Hevy, sync your photos, and let GainFrame build your ultimate transformation timeline. To get the most out of both apps, check out our tips for better progress photos.
