Myoware sensor visualize data

Im looking at creating a tshirt that measures muscle engagement of a user via LEDs. From my research I know you can use a myoware muscle sensor combined with an LED shield. This is something I am looking at however my question is how would I be able to visualize the activity? in say an app?

As in for example if a user were to do a bicep curl the bicep area of the t-shirt would light up in a specific color depending on how much of the muscle is engaged.

How would I then be able to record this data via an app or something?
