Started at 3 stars, now after a few weeks of use I'm upgrading my review to 5.Well it doesn't do everything I want a smartwatch to do (acknowledge Duo Security prompts, have a Google voice app on the watch), it does just about everything else and does it amazingly well.Without having a Google Pixel watch to compare it to, but only an Apple watch of my partner's, I can say from my experience that this is as close as you'll get to an Apple watch for an Android device.Day 4: Google Assistant on my watch - so easy to set timers and reminders. Audio cues when running - SO nice to not have to look at my watch. The ability to download Spotify playlists and play them on my Bluetooth headphones while running - magic.Day 1 impressions:* The initial setup was a convoluted multi-step process, especially as I didn't even have a Samsung account.* The Galaxy Wearable app is faster and MUCH more useful than the Fitbit app. Unlike the Fitbit app, where there are some settings that you can only change from the watch, you can actually change settings in the app which are pushed to the watch. SO nice compared to flicking through a tiny screen to set settings.* The default band is too small for a larger wrist, so I'm already shopping around for replacement bands.* Unlike Fitbit, where everything is in one app, you need to install another app (Samsung Health) to look at health data. BUT it's looking like I won't have to pay for advanced data, unlike Fitbit Premium, which is $80 a year if you pay annually ($10/mo if monthly).* Compared to the Fitbit Sense, the Galaxy 5 battery is crap, but that makes sense considering how much more "active" and engaging the UI is (which is more akin to the Apple Watch). With my Sense, I only had to charge the battery every 3 days - I'm already getting a sense that the Galaxy 5 will have to be charged every day.* The UI on the 5 is SO much better than the Sense. And faster. OMG, I love this thing compared to the Sense.* So far, sleep data is NOT accurate. I know I got about 8 hours of sleep last night, but the 5 says 5 hours.* Apparently, WearOS 3 is NOT compatible with Duo Security - so you can't acknowledge Duo notifications from your watch. BOOO!
