Fitness Duo allows you to easily track your fitness progress. Take daily pictures with this fitness tracker and view your results over time. Do it for long enough and you will have a nice before and after picture!
This app provides a convenient place to log your weight and appearance over time. Simply take a picture each day, add your weight, and then compare your photos over time. This app also allows you to view the weight you have lost (or gained!) in a graph.
You can also easily take a screenshot of your before and after comparison.
Have a good workout!
