I LOVE LOVE LOVE this watch. I hate to say that about anything but I have to be truthful.My husband bought me what I asked for, a Fitbit for MD. It worked fine, user friendly and all but the flimsy ratchet band is its weak link; I broke it easily the first day. That and the pins to fiddle with and be lost when replacing the band, smh—stupid design. So he returned it and I order a Huawei watch3 which, if I’m honest, I liked better than the Fitbit in looks and and strength in the band—but again that awful ratchet thing. It’s biggest problem was the screen wouldn’t swipe easily which I dont know if it was a defect or what, and the app is no bueno. Returned it and guess what? The Apple Watch 3 was on sale, only a few dollars more than the original Fitbit I had received. Now I am a long time Apple user—iMacs, iPads, iPhones, MacAir, etc, kind of sickening really—so I shouldn’t have been surprised they are up on their game. (Though I still use iPhone 7+ and don’t see I’m missing anything in my dtrs Xr.)I haven’t swam with it which was my prime motivation for a fitness watch but will update when I do. You have to download a sleep app and that worked great I’m sad to say—sleepless night last night. I hiked with it this morning and it seemed accurate, easy to use. I return texted my dtr on it all last night just to do so—you can speak your text or write it with your finger, both work great.I actually haven’t used the music or radio functions which require a Bluetooth headset but mine downloaded 11 minutes of my favorite music. It has a camera function which I find it misleading to say it has a camera—it is essentially a remote for the camera which is on your phone. Of course I couldn’t imagine a real camera being this tiny but I couldn’t figure out how it worked either until I heard my phone snapping pictures of the counter from across the room.I quite like the Breathe app which sounds ridiculous but we are a nation of shallow breathers because we don’t exercise enough (well I swim three hours a week and hike two but most people don’t.) Yet I like being reminded to focus on breathing and I set it at the longest intervals so I will deep breathe—good to lower blood pressure.I love the many faces of this watch and after playing around with them, even using a recent picture looking down into my Betta fish tank and the mandala made of its colors decided on the traditional look ( all above) with my monogram.I will eventually get more bands and a cover but for now the white matches my iPhone so I’m happy. Someone said you’ll never need another watch and I’d say that’s correct—until series 6 or 7 maybe.Oh one thing more, I don’t know about the battery life yet and some people complained you can’t wear it to sleep because you’re charging it every night; my question is why? Do you not sit and watch tv before bed when it could be charging, or are you going to rate that too somehow? Or charge it in your car on the way to or from work. Time management people is all I can say—no pun intended but it’s a good one huh?Update June 12, 2019: I have swam with this watch multiple times and love it. It not only tracks your laps but tells you which ones you did—even an ‘unknown’ lap when I was dolphin kicking but making nonsense arm motions just to get it to track bc it won’t track when you’re arms aren’t in motion. It gives calories burned as well as split and auto sets. I keep my heart rate on that screen too because that’s most important to me as I do intermittent cardio while swimming. (I do see now that the step counter is quite off for me. I do not believe I often walk 15,000 steps a day just around the house or even shopping. )Sadly I did find the battery has a very short life if you use it as it is factory set. I was having to charge it twice daily but then I found how to adjust settings for battery conservation on the Apple site. Now it lasts a good 27 hours or so without charging. I have to tap to get the time but the constant glowing face in the dark when flicking the wrist was annoying anyway so that works well for me.I really like the flashlight on the watch as I often go to bed after my husband so I can see and still use my hands unlike a phone or handheld flashlight. One more thing, the alarm on the wrist is particularly handy so you don’t have to wake the whole household when it’s only yourself getting up. (Well I only need a wrist shaking to wake up; if you need four alarms this won’t work for you, lol.)
