What customers say about "Key Specs"
Fitbit Ionic Charcoal/Smoke Gray, One Size (S & L Bands Included)
  • Apps that are available are actually pretty good! Doesn't include everything though.
  • They're really good at building fitness tracking hardware, and developing an incredibly solid app interface. Expanding to building a full operating system and managing an app store just seems like a bad move.
  • The current (rollout) features are very good, and I only expect them to get better as the system matures. Apps are scarce right now, but it looks like developers are adopting the tools and building for the platform in decent numbers.
  • The band is quite stiff though but perhaps I have to break it in.
  • I also like that Fitbit included two different sizes of watch bands instead of wasting everybody's time measuring their wrists.
Garmin Vivoactive 3 Black Stainless
  • Fits any quick release 20mm band and has plenty of downloadable faces so customization is huge.
  • The watch looks wonderful - I wear it to the office and I like that the diameter is smaller than other garmin watches. I previously used a Fitbit but now having used the garmin I won’t go back.
  • It also uses a Proprietary software instead of a OS. Battery life is real kickass. I have seen battery usage of 15-20% per day with bluetooth turn on/off as needed instead of having it turned on all the time.

  • The pictures in the description are very misleading. the screen resolution is significantly lesser quality than that of other smart watches.

What customers say about "Display"
Fitbit Ionic Charcoal/Smoke Gray, One Size (S & L Bands Included)
  • The display is easy to read while running and you can customize the displayed stats.
  • The screen display is bright and sensitive, and the watch itself was extremely intuitive to setup.
  • I switched from my old Fitbit Surge to the new Ionic and I absolutely love it! I find the display so much easier to read.
  • Screen saver timeout is not currently adjustable and only stays on for 2-3 seconds.
  • Only "run" activities are displayed in the Strava app on the Ionic. I do other activities too, it would be nice if they were displayed as well.
Garmin Vivoactive 3 Black Stainless
  • Display is good and the backlight is plenty bright. I have it 40% brightness and it's fine there.
  • Display is easy to read when under good lighting conditions due to reflective screen.
  • Display is good and the backlight is plenty bright. I have it 40% brightness and it's fine there.
  • Really the only thing that bugged me is that the display is not as sharp as Fitbit's. The back light washes out most colors and leaves a blue/indigo hue.
  • The screen is truly clear in the daylight or a well lit room, but like an actual watch its hard to read anything without the back light in a darker setting.

What customers say about "Features"
Fitbit Ionic Charcoal/Smoke Gray, One Size (S & L Bands Included)
  • Automatic sleep tracking - and, it can shut off notifications once sleep is detected
  • Sleep tracking is pretty good! Definitely better than an app you can get on Apple/Android watch.
  • The features are easy to use and access, A few trial and error and you will get how it works. Often use functions are just a few tabs away. You will familiar with it almost instantly. Love it
  • Slow performance from time to time
  • Can't connect to WiFi... any WiFi... Home, work, with or without password. Any firmware update needs to be done over Bluetooth and it takes 30 minutes to 1 hour. It is ridiculous.
Garmin Vivoactive 3 Black Stainless
  • Fairly accurate heart rate monitor, and activity and workout tracking
  • Ability to connect to external heart rate sensor is a huge plus in my opinion
  • Advanced dynamics on workout data are very informative
  • Gets notifications from your phone and can do some simple responses from the watch
  • Charging of the watch isn't wireless or anything... so there's a cable that you have to plug in to the watch to charge
  • Side scrolling can be overly-sensitive.
  • The gesture-operated back light algorithm is frustratingly slow. I turned it off and tap the watch when I need the time in dark rooms.

What customers say about "Power"
Fitbit Ionic Charcoal/Smoke Gray, One Size (S & L Bands Included)
  • Great battery life (4 days), very fast battery charging, reasonably accurate GPS, monitors your sleep, you can easily swap out third party watch bands, and recognizes when you go up stairs.
  • Long battery life - I made it from Tuesday to Saturday before it needed a charge.
  • Excellent battery life. Without GPS tracking, I left everything enabled and still charge every 6 days. All notifications are active.
  • In terms of battery life, it seems on par with my Blaze. Today is day 4 of owning the Ionic and it is still on the initial charge it came with (with notifications off).
  • I like to charge my fitbit when I shower (yes, I know I could shower with this one, but I like to clean my arm, too). I have a nice, convenient metal surface where I can stick the charger for easy retrieval.
Garmin Vivoactive 3 Black Stainless
  • Good-great battery life when only in smartwatch mode with optical HR monitor on -- I'm getting about 7 [updated] days in this mode. *BUT* once GPS is on, battery drain is poor
  • Had it on for a couple days and battery is still going strong without charging out of the box (70% when I opened it up).
  • Battery life is good, not as good as the original Vivoactive but still really good considering the size and what it does. After 24 hours off the charger and going on 1 four mile run, the battery is at 67%.
  • The battery life is advertised as being 7 days - this may be true if bluetooth is off and you don't use the watch at all, but as far as the real world is concerned, 7 days is kind of a fiction.
  • GPS battery life is definitely NOT 13 hours (as advertised). I get about 8-10 hours of GPS use for runs/bike.
