I can make that charts in Tableau software and it has free mobile app that will enable you to track it.
I have official license of tableau so you do not need to buy it, and the mobile app is free.
I offer you to make this dashboard mobile app for free, and if you satisfied with it , you pay for me
Also, I am data analyst using Python ,Tableau and excel, and I am holding MBA so I will make data analysis for you
from businesses point of view.
Kindly contact me to show you my previous work in Tableau , and discuss more details
