All controls come with a "UserData" field. I would use that, In "startupFcn" initialize to zero
app.Button.UserData = 0
Then in the button pushed function
app.Button.UserData = app.Button.UserData + 1;

See attached GUI. When you press the Go button, it counts up and put the result into a text label on the GUI. When you press the Stop button, it stops.
