@Ruslan Avramenko - in the restart button callback, you will want to compare the number in the high score field with that in the current score field. Something like
function RestartButtonPushed(app, event)
stop(app.t);
app.Label_3.Text = num2str(max(str2double(app.Label.Text), str2double(app.Label_3.Text)))
app.Label.Text = num2str(0);
app.Label_2.Text = num2str(60);
app.t = timer;
StartButtonPushed(app,event);
end
I think that you could make these two fields, Label and Labe_3, numeric text fields so that you could avoid the conversion to and from strings.
