TOZO S2 44mm Smart Watch Alexa Built-in Fitness Tracker with Sleep Monitor,5ATM Waterproof HD Touchscreen for Men Women Compatible with iPhone&Android Black

This watch is fantastic. Big, nice looking watch faces, vibrating alarms, and super affordable. I liked it so much that I gave it away to a friend during a tripand bought myself another one when I came back.

Streamlined easy setup instructions and navigation of the app: once fully charged, the watch prompts you to download the apps to your phone. Open the app, 'Scan QR Code' (on the watch screen) then can add the device -- this is really SUPER convenient! Bluetooth connection is effortless. From the "Edit Card' of the 'Home' screen of the app, you can add/enable/disable the gadgets on top of those default ones. Navigate to 'Exercise' screen then you can start GPS enabled Hiking, Indoor/Outdoor exercises; switch to 'Device' screen, you will get the set up for enable/disable Notifications from your phone like email, SMS, messaging, phone calls, etc., and config for 'Alarm clock', 'Health', AND tons of Watch Face selections for download; go to the last screen 'My', you will get all your exercises and health data, goals, preferences, and other settings specific to youFunctions: don't want to repeat what's been already mentioned in the product website, and truly they are all in this smartwatch -- a ton, and fairly comprehensively a health tracker that can fit into a watch, I can't think of if anything else needed. For Heart Rate monitoring, I chose 'Intelligent monitoring' vs 'Real-time monitoring' -- the latter will consume more battery and not needed for me, and I also enabled 'High heart rate alert'Anything could be a bit better, at least for me: Blood Oxygen (spO2) would be nice if can be directly navigate on the watch the same way as Heart Beat or Stress -- currently you will need to go to 'Function' (press the button of the watch) in order to get to it. Also, battery wise, seemed to be like what the product says 7-10 days, but the 'wrist awake' and touch screen seemed not as responsive when the battery is about 20% left, so I rated the battery life as four starts. I haven't got to try the 'Sleep tracking' yet but will see how it goes.All in all, I gave it a 5-star rating - can't be wrong to buy this smart watch with such a great price! I bought my Fitbit wristband for $99 each for myself and my wife just about 2 years ago -- that just CANNOT be compared with this smart watch. As a matter of fact I like it a lot so that I just got one also for my wife -- it comes with rose gold wrist band, the model is S2, my black wrist band is S2 Pro, unsure what's the difference but I tried out all the functions, seemed to be the same

I've had this watch for almost two months, which seems a reasonable amount of time to have a good view of how well it works. It's important to note (in case the price point didn't make it obvious) that this is NOT an Apple Watch, and expecting it to be one will likely disappoint you. (I haven't ever owned an Apple Watch, so I can't do a direct comparison.)I have an iPhone, so I was hoping that the watch would fill in the gaps in my step count when I'm not carrying my phone. It does, to an extent, but the sync is iffy. Sometimes steps (and other data) don't seem to sync at all. Other times the count in Apple Health is wildly high, and when I look at the data sources, the Tozo data is shown multiple times. Re-syncing via the app usually fixes this, but it's frustrating that it can't just sync properly.When I've contacted Tozo support, which is usually very responsive, they tell me Apple Health is not supported, and yet... the Tozo Fit app is clearly available as a data source, and the steps usually sync just fine. What will not sync, oddly, is workout data. That has to be entered manually. The watch does seem to do a good job here, though when I use the rower, it seems to register each stroke as a step despite the fact that I've put it into rowing mode. I honestly don't mind getting "credit" for my workout that way, but if you're strict about your step counts, that may be an issue for you. I suspect it falsely records other actions as steps as well (there's no way I'm walking 45 steps to the bathroom in the middle of the night, for instance).Sleep seems to be pretty accurate, and is my favorite feature of the whole thing. I like that it shows a pie chart of time in light sleep, deep sleep and awake. Heart rate and pulse ox seem to be solid functions, too.I'm not into annoying bells and whistles, so I have anything that buzzes or beeps or flashes the screen on turned off (including the watch face--I'm not actually into watches and I certainly don't want the thing lighting up every time I move, which I find horribly distracting). I don't have phone calls or text messages hooked up, and I don't use Alexa, so I can't speak to any of those features. I am glad so many things can be silenced or turned off, though--otherwise I would never be able to tolerate the watch at all.The only reason I've taken a break from using it at the moment is that it's made me break out in a rash, which I suspect is not an allergy but just a result of constant contact with my skin. I've tried alternating wrists, but one is more sensitive than the other, so that doesn't help. Be aware that this may be an issue for you, too. There are several articles online suggesting ways to prevent skin reactions with watches/trackers that you may want to consult before you consider giving this sort of device a try.Overall, I'd say it's a good device for the money. It's not perfect, but for most people it's probably close enough.
