Has anyone else noticed that if you leave the house with wifi on your phone "on" that it seems to slow down your watch for some tasks? When I have my wifi on but I'm not in range of a network is the situation I'm specifically referring to. A couple apps that I use a lot on my Apple Watch when I leave my house are Runkeeper and Downcast. Since I'm running I use SIRI to launch or switch to another app. I started noticing that if I had my WIFI on that it slowed down these apps from launching fully. I suspect the slowdown was not totally the watches fault but also had to do with my iPhone looking for a wifi network first and then switching to cellular. I started turning my wifi off before going out for my runs and Siri seems much snappier. Also, asking Siri to text for me is much better with wifi turned off. Anyway, here's something else to try if you are frustrated with your watch response times.
