This is a great app if you are a fitness trainer or a fitness enthusiast and want to track your progress. You can record your height, weight, body measurements (neck, chest, arms, thighs, etc.) and helps you to calculate BMI, BF% and more. You can also visualize your data in graphics, helping you to track your body in a friendly way. The only thing I dont like is that it doesnt convert units and you cannot also combine metrics with imperials (cm and lbs) for calculations. Overall, this is a very helpful app and its FREE.
