In short
ProgressLens is a body measurement tracker with progress photos. It records bodyweight, waist, chest, shoulders, arms and thighs, in pounds and inches or kilograms and centimetres, shows a chart for each, and keeps them on the same timeline as your front, side and back photos.
Why both
A smaller waist with the same weight? Now you’ll know why.
Weight jumps around with water and salt. Your waist and a matching photo don’t. Put them side by side and you can tell fat loss from a salty dinner.
