I just won an Apple Watch (Series 4) from a contest at Cherwell Software, but I don't use an iPhone as my primary phone. This blog post is the first in what will be a series of blog posts about how effectively I can use an Apple Watch with or in spite of my Android Phone.
Recently my primary phone is a Samsung Galaxy S8 and I've worn a Fitbit (secondhand and free) for the past year. Primarily, I use it to track steps and sleep. I don't do particularly intense exercise or sports, so the Fitbit's been a glorified pedometer and sleep tracker. The Apple Watch tracks steps natively, but to track sleep the way I have been on the Fitbit requires a separate app, like Pillow. At least for now, I'll test out Pillow and see how it compares to the Fitbit.
Another thing I'm curious about is the charging schedule I'll need to use. This was something I was concerned about when I started using the Fitbit as well, because most people seem to charge things while they sleep, but sleep is one of the things I track. Instead, I've typically charged the Fitbit while I watch TV in the evenings or while I work on side projects -- some point in time when I'm fairly sedentary so I'm not missing out on valuable data. The Fitbit only needed to be charged approximately once a week, so it was only a periodic inconvenience. Hopefully the Apple Watch will live up to the high bar the Fitbit has set.
Finally, I'll be curious to see if there's any way at all I can manage the Apple Watch from my Android phone. I'm not holding my breath on this one, given the general lack of interoperability between the two ecosystems, but that won't stop me from looking anyway.
