Web platform/app platform

Are there gonna be any portal with platform where I can compare athlete by athlete on a specific exercise ? For example I have two athletes squatting same amount of weight but they have different power output. I wish to compare their results.

Also it could work as a training log for us. Not just like in history I can only search specific exercise or set. I wish to find whole day. What exactly I have done exact day as a whole. Also a total tonnage of whole workout would be cool.
