Contura 3.0 - See body change without recreating the same photo twice

Progress photos are hard to repeat. Same pose, same lighting, same angle — and somehow a clear view of your back. Most people give up after a few weeks. Contura takes a different path. Enter your height, weight, and circumferences. We build a private 3D body on-device. Compare any two moments — past, present, or projected — on the same model. Red shows where volume increased. Blue shows where it decreased. No photos. No camera scans. No account required. Body data stays on-device by default.
