I went to the store this weekend to get the Nike Fuel, but they didn't have it. I bought the Garmin Vivosmart instead. The picture could be better, it was nearly impossible to photograph the display.
I took a chance that I could get BG data onto it in a usable way. To do this I'm just sending a notification from the iPhone. Three taps whenever you want to see your BG. The only negative is I can't control the buzzing(when the notification is received), other than to turn it off.
This is the perfect device for the gym. The watch is too bulky, and potentially dangerous to other people, and of course, people wonder why you are wearing it in the first place. Lots of people are wearing trackers these days, it's low profile, all rounded edges and it's just black plastic until you tap it. Have I mentioned the time someone asked me if my HR was really 185? ...
From the iPhone you configure it to only keep 1 notification, so the new one always overwrites the last. On the Vivo, there's a privacy setting where you turn alerts off, if you leave it on, you'll get a brief buzz every 5 minutes. If that option could be configurable by app, I could get this to do alerts. But, as it stands, it's all or none.
