Hello, i can do it using bootstrap along php-MySQL and highcharts, have done a lot of them here, so you can check my reviews.
Have a couple of question, on first_screen_and_set_new_goal page, the dropdown, you will provide all the options to be there?
And the movement box, what it should store? numbers to be displayed later on the chart?
Also, the other dropdown menu (in green, without text inside), what is it?
On next page: main_screen, what are those 2 dropdown menus?
I think you would have to help me understanding the 'flow', but i can do this for sure.
Thanks!
