Mobile app

Hi! I am looking for someone to create a mobile app for me to use for my nutrition and fitness clients! I am a certified personal trainer as well as a certified nutrition coach, and would like to make an app for my clients to use. In this app, I would like to be able to communicate with my clients, as well as adjust their macros and calories. As well as create workout plans for them to use. I would like the look to be clean with nice geographical simple lines but also cute and pretty! Colors ranging in white, light blue, light orange, black, and darker blues and darker oranges.
