Track your weight, BMI and take perfect progress photos with our AI assistant. Compare them side by side or make a progress video of the past period to see how you've changed. A lot of people take progress photos to visualize their progress and keep motivated. Thousands of progress photos are taken every week and shared on the internet, but there is one problem: the majority of them are not really comparable. The before and after photos show different poses, the person is partly visible and/or the backgrounds are different. That’s why we created BitBody Shape. Our AI assistant tells you how to pose and takes perfect progress photos when you stand in front of the camera. You only have to follow the instructions. This, in combination with the option to change the backgrounds, results in progress photos that are truly comparable to each other.
