  • Great battery life, love the bright easy to read screen
Color: Carbon/Graphite
I am a long time Fitbit user. I upgraded from the Fitbit Charge 3 because I couldn't read the Charge 3 screen at all in the sunlight. The Fitbit Sense is easy to read even when it's sunny out. Great battery life & charges super fast. Sleep mode is very helpful. I really wish that you could fully read text messages & emails on the Sense. Also wish you could see your full reply when responding to someone via voice to text. Sense isn't useful/helpful when you have to use your phone to see full text messages, emails or your voice response to make sure there aren't any wrong words in your voice to text before sending. The purpose of those features are so you wouldn't have to rely on using your phone. Also, sometimes when you press on a notification Sense will occasionally clear other unopened notifications. It doesn't happen often but is frustrating when it does. In exercise mode I wish there was an option to see the current time in addition to elapsed time, distance, pace & heartrate all on the same screen. It would be helpful when doing 5k races or training for a race. I do like the current option of seeing those on separate screens too but would prefer the ease of seeing all on one screen. Golf mode has shut itself off a few times when I've used it. That's disappointing when you're trying to keep track of total play time & total steps specifically during the hours of playing golf. Wish I could get the "Golfpad" app on my Sense then I could use my Sense instead of the app on my phone. Also wish there were more free clocks similar to Spectrum that showed current time, date, steps, sleep & heartrate on one screen with a nice picture background that was easy to read. Overall I love the Fitbit Sense. I plan to try more of the other features such as music soon & hope I can listen while keeping the walking exercise mode running during a race without a problem. Hopefully I'll be able to switch back & forth quickly & easily. I bought the screen protector for my Sense & have been using it since. So glad I did as it's protected the screen many times from being bumped or accidentally dropped when trying to put it on. Wish Fitbit would sell the screen protectors. Would also like more color options for the sport bands including an all black band and breathing holes. The sport bands & Sense are very comfortable to wear even while sleeping. I recommend the sport brands if you play a lot of sports or are very active to ensure it stays on. I love the square face of the Sense. It's large enough & bright enough to read indoors & outdoors yet delicate looking for a small wrist. One last thing, wish Fitbit gave a better way to sign up for the extra extended coverage. The option popped up on the app on my phone but unfortunately while I was at work & didn't have the credit card on me I would have used to pay for the coverage. So unfortunately I didn't get a chance to sign up for that. The Sense is rather pricey so worth waiting until it's on sale. ... show more

  • Personalized and Informative Value
Color: Carbon/Graphite
Fitbit Sense has a lot of personalized information to help you reach your goals and also improve your health. Resting and current hear rates, personalized notifications, sleep quality and quantity so you can improve areas. Average Pulse ox readings for overnight and discussion with your healthcare provider if needed for a more detailed look if needed. It has been invaluable and the battery life is great. ... show more

  • Nice features - needs work
Color: Carbon/Graphite
I’ve been a Fitbit user since 2012 and having used at least 7 different devices over those years (Zip, One, Force, Charge HR, Charge 2-4) - long enough to know where they’ve hit the mark and where they’ve missed it. The Sense was an upgrade from my Charge 4. Where it excels: - Watch face: allows you to choose the face with many free and paid options ($0.50 - $1.50) - Built in GPS (same as Charge 4, handy feature) - Sleep tracking: includes optional SPO2 monitoring with an additional free app installed to the watch - Apps: you have a number of different apps that you can download to the watch - Exercise tracking: Charge let you add your top 5 exercises to your watch for quick add. Sense has the complete list already on it - Water logging: can be done right from the watch (awesome!) - Weather: you can add an app to see the weather on your phone. Supports multiple locations - Music control: right from your watch (Pandora, Spotify, Deezer) - Voice assistant (Google or Alexa), EDA scan, find my phone, answer calls from your watch, full text message viewing, and ECG are new additions from the Charge 4 - notifications to drink water during the day (optional setting) is helpful - Alarm will monitor your sleep to wake you at the most opportune time (not in the middle of REM sleep for example but before/at the time you set) Now for the bad… - Claims to hold a 6 day charge but with basic use and some daily exercising, I find myself charging it every few days - watch faces are nice but you can only keep 5 on hand in your app. If you accidentally write over a paid face, its a pain to get it back without paying for it again - watch disconnects from your phone very frequently requiring one to open the app constantly and sync to restore the connection - find my phone (one of the features I was really looking forward to) rarely works because the watch disconnects from the phone so frequently - ECG regularly says the results are inconclusive despite remaining perfectly still - Missed notifications (calls. texts, calendar, drink water) - a constant issue because the watch doesn't stay connected to the phone - Doesn't seem to sync in the background despite all the settings on the app, watch, phone indicating it should Aside from the frustration around stuff constantly not working because watch disconnects from the phone, the vibrations on the watch are sad - even with vibration turned to “strong”. Additionally, the Charge 4 had different vibrations depending on the notification (reminders vs calls vs texts, etc). The Sense notification vibrate are all the same, and can barely be felt. I don't rely on the watch to wake me up whereas my Charge 4 was an awesome alarm as the vibration was so strong. Am I happy with this watch? Eh. It has a lot of potential if these main issues are addressed by way of software updates or hardware upgrades in v2 Side note: all my complaints are echoed on the Fitbit Community pages which tells me its not a problem with the device I received, its issues with Fitbit Sense in general ... show more
