Very useful
I’ve just recently started using this method and this app (mac and iOS) is the best of the three I’ve purchased. Since I am mostly using this while coding the Mac version gets the most use of the two (or three if you want to count the watch separate). It would be nice for it to share its state between the phone and Mac. Other than that I really like it and use it every day.
