I just bought myself the latest Apple Watch! I had the original one - the Series 0 - and just upgraded to the Series 3 (without cellular support). I use my watch all the time - I keep track of my heart rate, exercise, and it is my main interface to my phone when I am out and about.

Recently it became really slow to start up the workout app on the watch. It would lock the watch up for a few minutes. This was extremely irritating when I was just starting a run, but would have to wait until the watch unlocked before I could start tracking it. I am hoping that the new watch will solve this problem.

I am also doing a lot more iOS development at the moment, so I am looking forward to building some Apple Watch apps!
