Hello sir,
I'm badarinadh working with PHP technology from the last 3 years. I'm capable of creating responsive websites. I have some ideas which can be useful for your project. We can make use of graphs, where users will enter their details(weight,height,.....etc) on weekly basis and we will give them the report in graphical way so that they will be attracted. There were some more ideas to implement.
please give us a change and i'm sure you will be satisfied with the output for sure.
regards,
badarinadh
