Amazfit GTS 4 Mini Smart Watch for Women Men, Alexa Built-in, GPS, Fitness Tracker with 120+ Sport Modes, 15-Day Battery Life, Heart Rate Blood Oxygen Monitor, Android Phone iPhone Compatible-Black

This is a fabulous watch. The display is bright and vibrant and there are a lot of watchfaces you can choose from. The battery life is great. There are ton of features you can turn on or off though the app. It was simple to pair to my phone. I like being able to see my text messages without having to pull my phone out of my pocket. There are a few third party watchface apps that you can use to get even more faces than the Zepp app.

Amazing product, the functions and all the sports that can be tracked are very good, great design minimalista and pretty, the size is very reasonable nor very large and big enough to navigate through the options.The most outstanding feature is the insane battery, I almost got two to three weeks depending on the activities done, measure almost all the movements, sleep, stress pretty decent job ver very recommended the price is great!

I've been using this watch for about a week now, and there are things I am impressed with and some things that leave me wanting. The display is clean and crisp, and while the included watch faces leave a little to be desired, they are OK. Battery life is good, but if you have it do all the tracking and leave the display on etc., it is about 3-5 days. it is lightweight and comfortable on my wrist.A couple of things I don't like. The Zepp app is not perfect, and finding some settings takes some getting used to. Overall it is decent but could use some tweaking. Probably my biggest complaint is with the step tracking. It is just not very accurate. I went online and tried to find some ways to tweak it, but nothing matched up to my watch settings. They base the counter on arm swings. The problem is I do things where I am walking, but my arm is stationary. In those cases, it is way off. The other health monitor things seem to work fine, at least as good as I would expect from a watch. For $89.00, it is a great deal; I just wish they would tweak the app and make the step counter more accurate. Those two things lost them a star.

I've had the following watches: Moto 360, ZenWatch 2, Galaxy Watch (1 & 3).Most of those met an untimely end due to ONE issue, the firmware would get updated and the device would become unbearably slow. Google Watch OS or Tizen OS, didn't matter. The Moto, however, had display issues that Moto wanted me to pay for fixing (under warranty).These are a breath of fresh air. No fancy gimmicks or useless gizmos. They did a great job including features that are useful but not wasteful. Most importantly, the OS (i think it's RTOS) means it's never slow.The battery life is great. I went on a week long trip to my sister's place and didn't need to bring a charger. Used AOD 50% of the time (timed to turn off after 8pm, back on at 8am).If you want a smart watch that you can receive notifications with, but that doesn't require you to watch the battery percentage all day, this is fantastic at it.Couple of caveats (forgiven at this price point):1. Glass isn't very durable, I've got a few chips in mine.2. OS isn't super stable. I've seen it crash and reboot a few times, but the reboot time is very fast.3. Watch faces aren't really that great on the market. I attempted to make my own and you have to upload an individual picture for each number, for each position. Who designed that???4. AOD will not have the numbers line up exactly with the watch face. This is by design to save the screen from burn in.5. It should be easier to have maps display route guidance (just next turn direction and distance is all you need). Currently you need to install a companion app (which requires permissions it doesn't need) and if you put your watch down for too long (you know because you are driving...) it will put the app to sleep and you need to go back in to open it again. At the very least, remember what app was open and open back up to it.6. Duplicate text notifications. I believe this to be an API limitation from Android. However, you can solve this in software by keeping track of recent texts and double checking they aren't the same before displaying them. I've programmed a system like this before for Twitch's API due to mirror update lag. It's not beyond capability.7. The companion app (required for a lot of stuff to work) seems to collect and sell your data to offset price on watch. I'm personally fine with this, but you should know that before you buy.

After buying and returning at least 8 activity tracker over the past year. I finally found one with perfect battery life, easy to charge, and wonderful working features. The only down is that it has no blood pressure measurement available, but I really don't know how accurately blood pressure can be measured on a watch. Very happy with this purchase. Great value. Easy to read display and effortless and accurate synching via Bluetooth. Not happy with band color, so I replaced it with a more appealing color to me

I have had this watch almost a year now & it has lost the ability to receive text messages or Facebook messages, it just stopped working. It tells me there is a call only sometimes. It only ever charges up to 92% for some reason, no matter how long i charge it. The bands are very difficult to switch out, I had gotten a different band but I couldn't get the tiny pins to work, so I sent that back. It does do all the fitness things well. It gives accurate heart rate. I like the watch faces alot. & I have gone snorkeling in the ocean with it on for over an hour with no trouble. It works well to remind me to get up & walk. & has an alarm feature that also works well. The battery lasts about 2 weeks. I just wish it would still give me my messages. For this reason alone I'm going to buy a different watch.

Super loved in this watch! The battery life is very long, I used this for almost 2years now I even dont have a problem with it the battery will stay at least 5 days for me. I recommended this watch to all who love a watch specially those love doing fitness it will track everything from the health. Just download a Zepp App. and it will connect to your phone. Has a lot of free wallpaper also it can connect to your Alexa. And yeah! I love it so far.
