After 3 Days My aim was to buy a watch with fitness/workout/sleep tracking comparable to an Apple Watch but which was stylish enough to wear to work. I wear a suit to work in a Four Diamond hotel, so not just any watch would be fitting for my daily dress code. The Withings Steel HR Sport meets these requirements wonderfully (and, compared to Apple, cheaply)! Setting up the watch and syncing it to my phone was a breeze. The Withings Health Mate app has a great aesthetic, and the process was very straight-forward. The app does have you calibrate all of the dials (the crown on the watch doesn't turn - it's just a button - so you move the dials with the app on your phone), which felt tedious, especially for the small steps-goal %. Fortunately, you can re-calibrate at anytime through the app if you get it a little bit wrong. Withings recommends wearing the watch one finger-breadth above the bone on your wrist. This is to ensure the HR monitor isn't put at any funny angles and can't take readings. I've been wearing mine comfortably lower than that (closer to my hand), and I've had no trouble getting HR readouts. The HR monitor is really slick. Throughout my day, it's taking measurements (every 10 minutes, I believe), and I can pull up the app and see what has been measured. I can also use the button to initiate an HR reading at anytime (It will immediately display the results from the most recent reading, if it quietly took one in the background, and then take a new reading if you wait just a moment on the HR screen.), and then when you go into fitness mode, it monitors continuously (as well as initiates GPS tracking, when connected to your phone). The step counter has also been great to have on my wrist. Throughout the day, I have checked both the digital screen and the little dial to see how I'm tracking. And when you reach your goal, it vibrates and displays the step count to let you know. Tracking sleep data seems accurate so far. It does a good job of continuing sleep monitoring even if you get up for a short while in the middle of the night (such as when taking care of an infant). One morning though, I woke up, set the watch on the countertop while I took a shower, and found later it recorded my whole morning routing as 30 minutes of 'deep sleep' which inflated my 'sleep score.' You can go in and edit your asleep & wake-up times, though, so a quick adjustment made the data more reliable. Alarms are also based on your sleep cycle, trying to wake you up when you're not in a deep sleep. It has worked well for me so far. Also, the watch itself is hardly noticeable when I sleep (unless I don't turn notifications off), but the band it ships with isn't all that comfortable. I think I might get something fabric, not silicone, for sleeping. At first, I thought interacting with the screen would be frustrating. I thought that perhaps I would feel constrained. In fact, it's quite the opposite. It's almost a relief not to have a deluge of digital information on my wrist. The notifications have been great. I can see if a message/email needs to be checked right now or not, and if it does, I pull out my phone to deal with it (which is what all my Apple Watch-wearing friends seem to do anyway). The single-button design works really well, too. In the app, I can customize which screens the digital display can show. I admit, I haven't done much exercising with it - just a few long walks so far. I hope to have some exercise in before my next update to this review. After 1 Week The band included is really not that comfortable, I found, which is why I'm glad this watch uses a standard 20mm watch band. I ordered a different sport band, and the result was immediate. My wrist has been much, much more comfortable since.Gear Sport Band, KADES Soft Silicone Band Breathable Strap Compatible for Samsung Galaxy Watch 42mm/ Garmin VivoActive 3/ Ticwatch 2/ Ticwatch E/Amazfit Bip Smart Watch- White/Black Sleep tracking has worked really well. Sometimes, if I set my watch down shortly after waking up, the watch will think I'm still sleeping. I've been surprised a couple times to see that the app shows I was in a 'deep sleep' when in fact I was showering or brushing my teeth. Withings made it quite easy to go into the app and adjust the 'wake up' time, so that any sleep data collected while you were awake is disregarded. For the most part, the notifications on the watch have been really useful. Even though they're just short snippets of text that scroll by, they've still been useful. I much prefer glancing at my watch instead of pulling out my phone from my pocket to see who that text/email is from. Notifications only work, though, for applications which have been integrated by Withings. I wish there was some way to see notifications from other apps on my phone. For example, I use Waterlogged on my iPhone to help me ensure I'm drinking enough water throughout the day. I wish those notifications popped up on my wrist as well as my phone. There are no move reminders. If you sit all day long, your Steel HR Sport will not complain (unlike an Apple Watch or Fitbit, for example). Perhaps there's a way to use an iPhone app which can send such notifications, but I haven't found it yet. The battery life is incredible. I put this on the charger on October 10th (just to try it, not because it actually needed charging). It is now October 16th, and I'm at 58%. That includes several sessions tracking activities. Activity tracking seems to work really nicely. It even automatically detects workouts. I had a little impromptu soccer game with my two-year-old. I was running around, heart rate elevated, for about 15-20 minutes. As we walked away from the field, my phone buzzed with a notification "workout detected." It automatically categorized it as 'other' (which isn't surprising, soccer with a toddler is a pretty unique set of movements), but I could easily hop in the app to change the category and add notes so that it was recorded effectively to my log. I've been using this in conjunction with dieting to. The companion app Health Mate ties in with MyFitnessPal very well for comparing calories burned with calories consumed. One downside to mention is that I'm not sure the Steel HR Sport counts stairs climbed. On a walk I tracked, it counted elevation in the post-workout stats, but I'm not sure if that was from the watch's onboard telemetry or comparing GPS info to known topographical data from other sources. I've hit my 10,000 step goal a few times now. I love the little celebration notification that pops up. It's rewarding and well done. Finally, I really, really like the look of the watch (I have the white watch face). I've noticed at work a lot of folks wearing Apple Watches. To me, they know look large and clunky (especially with the extra armor/cases they put on to protect them). Every day, I'm quite glad to be wearing a watch that looks like a watch. After 1 Month I still love this watch. It seamlessly fits into my day-to-day as a pair of glasses or perhaps a favorite coat. I'm not often presently aware that I have it on, until I check the time or perhaps my heart rate. Notifications work better than previously thought. The companion application becomes 'aware' of a notification after it has appeared on your phone. Here's a step-by-step of how to get an app on your phone to show notifications on your watch: 1) Install app on your phone (this app will not show up in the watch's companion app yet). 2) Have the app ding your phone with any notification (now the app shows up in the watch's companion app) 3) Open up the Health Mate companion app, and enable your notifications. 4) Enjoy getting buzzed on your wrist. Additionally, it seems there is a correlation in battery life and notifications. If your watch is buzzing every couple minutes all day every day with notifications, the battery wears down more quickly. Even so, it still seems to last forever. The watch band that
