Feature
Side-by-side before & after photo comparison
Two photos, one honest answer. ProgressLens puts any two check-ins next to each other, aligned to the same pose and framing, so the only thing that changed in the picture is you.
- Drag-the-divider comparison slider
- Any two dates in your history
- Front, side and back views
- Silhouette shape delta highlighting
Compare any two check-ins
Choose a start and end date from your journal and drag the divider across the pair. Because each capture is aligned to your previous pose, the two images line up naturally — no cropping, rotating or guessing.
Pose alignment does the hard work
A ghost overlay of your last photo appears while you shoot, so distance, height and stance match every week. That consistency is what makes a comparison trustworthy months later.
Shape delta shows what moved
ProgressLens extracts a silhouette from each photo and measures the difference between them, so changes around the waist, chest and shoulders are visible even when your eyes say nothing happened.
Pair it with weight and score trends
Every comparison sits next to your logged weight and transformation score for those dates, so you can read the picture and the numbers together instead of trusting either one alone.
Common questions
