Great all round performance!
I recently picked up the TOZO S3 smartwatch, and I’ve been seriously impressed. For the price, it packs a punch! The first thing that caught my eye was the large 1.83-inch HD screen. It’s so clear and easy to read, even outdoors. Navigating the menus is a breeze, and notifications are displayed perfectly.As someone who’s trying to be more active, the health and fitness tracking features have been a game-changer. The heart rate monitor is accurate and gives me a good overview of my heart rate throughout the day. The sleep tracking is also really helpful â I’ve learned a lot about my sleep patterns. And with over 100 sports modes, it covers pretty much every activity I do, from running and cycling to more niche workouts. It’s great to have all that data at my fingertips.The battery life is another huge plus. I’ve been getting almost a week of use on a single charge, which is fantastic. I don’t have to worry about constantly plugging it in. Plus, it has all the basic smart features I need, like notifications for calls and messages, and music control. Itâs super convenient to be able to control my music without pulling out my phone.Honestly, for the price, the TOZO S3 is an amazing value. It has all the essential features of a much more expensive smartwatch without breaking the bank. If you’re looking for a reliable and feature-packed smartwatch that won’t empty your wallet, I highly recommend checking out the TOZO S3. You won’t be disappointed!

Great smart watch!
I have upgraded from Tozo S2, which I already liked, and this one’s even better – really happy with my purchase so far.I find the user interface on the watch itself very fast and responsive, no weird lag. There are multiple things you can track with this watch, most of them I don’t really bother with but it’s nice to have an option to track sleep quality, heart rate, etc. For everyday, it’s mostly steps and distance I track.The app is decent, it allows you to choose from a variety of watch faces, though my only complaint is how I’d like to customize them, for example some faces don’t have a step count where I’d like to add it, others have a lot of other info that I’d like to remove as it can look too busy. For the price point this is more than adequate though.Battery life is very good, only had to charge once per week so far.It is large enough and comfortable, I like the minimalist design, and the strap has a nice quality, not the tacky kind of silicone that catches every speck of dust and grime. It’s a classic strap with a metal fastener, rather than the type where you push a little knob through, and while it may at first feel fiddly, I prefer this since there are a lot of holes with tiny spaces between, which means you can find the perfect setting for your wrist.Overall, would definitely recommend.

Lovely watch – just be aware of a few minor things before you buy
Wife’s review as followsCame quickly. Charging is going to be a pain as the cable is magnetic and doesn’t actually fit into a section, it rests on top.Strap was a nuisance to get on initially but nice and secure once on. Easy to set up and download app. You can change your home screen and allow calls messages etc.Battery was 100% when I got it but dropped to 20% so I fully charged it and it seems OK for now – I will see how long the battery lasts.I bought this instead of a fitbit due to them taking away the group challenges and so far I’m happy given the price point.The strap is comfortable and the watch isn’t huge but the strap is annoying to attach. Overall very good so far

Excellent value for its price, providing a solid set of features for everyday fitness tracking!
The Tozo S3 Smartwatch offers excellent value for its price, providing a solid set of features for everyday fitness tracking and smart connectivity. It has a sleek, lightweight design with a clear, responsive touchscreen. The fitness tracking options, including heart rate monitoring, step counting, and sleep tracking, are accurate and reliable. The battery life is impressive, lasting several days on a single charge. It supports notifications for calls, texts, and apps, though some users may find the app interface a bit limited compared to more premium models. Overall, it’s a great entry-level smartwatch.

Breaks when u just open it
The worst watch i have ever bought in my life. Doesn’t even keep turned on for more than 60 seconds before u need to rest the whole watch to fix it. So exited to receive it for it to be a complete joke and waste of my money. would not even give it a one star if i could give it a zero i would

exceeded my expectation
Itâs a great budget smartwatch. display can be changed, notifications are accurate, I can even answer calls with sound audio. The battery life is pretty good, the straps are silicone and solid. it does have settings to record walking, running, strength, dumbbell exercises. Overall it seems to be doing its purpose really well.

Great
Easy to use and connect to Tozo health, the screen display can be changed which is really cool, notifications are accurate, I can even answer calls through the watch!! With a sound audio. The battery life is good but it seems to run down even when you’re on the tozo health app and really quick; however since I just use it too check the time and track exercise and stuff it’s perfect. You’ll only need to use the app to adjust settings anyways. Was a bit disappointed that I couldn’t link my Spotify to it though but oh well. It fits perfectly fine, the straps are silicone so are solid. I’d say it’s pretty accurate but obviously don’t know to what extent, I wished it calculated calories based off heart rate for things like exercises at the gym and stuff though, although it does have settings to record walking, running, strength, dumbbell exercises etc.

I have been a customer for several of Tozoâs excellent earbuds, and was offered the opportunity by Tozo to try out their S3 smartwatch. I took them up on their offer and would like to offer my take on the watch and how it compares to another smartwatch I have, the Fitbit Versa 3.Let me start out by saying that the Tozo S3 is an amazing deal. At a price that is a fraction of the price of the Fitbit, it is hard to believe that Tozo can put out a watch of this quality at the price at which they are offering it. While there are a few things that the Fitbit can do that the Tozo cannot, for the most part the Tozo can do everything most people are going to need.Here are some positives and negatives:POSITIVES:1. The battery life has been great. It is at least double what I get from the Fitbit. I know there are a lot of factors that influence battery life, and there are some things that the Fitbit can do that impact battery life that are not an option on the, such as the ability to have a power saving setting that still shows the time constantly. I do use that setting, and Iâm sure that impacts the Fitbit battery life. But that feature is probably not needed by most people anyway, and the battery life on the Tozo has been very impressive.2. The display is crisp and clear and set up logically. The physical button on the Tozo makes it easy to get into the menu system. Although it does not appear that you can tap the screen on the Tozo to wake it up like you can on the Fitbit, the wrist action setting works well.3. The app is excellent, and there are lots of option in the app to add many different exercise routines. More than what is available on the Fitbit.4. The Bluetooth phone connection works very well, and I was able to place and answer calls without a problem. Not unexpectedly, the sound is tinny due to the tiny speaker involved, but it was still clear and very usable.5. They have many nice watch faces available for download for free, and I found one that shows all the information on the main screen. Itâs nice that they give you so many options.6. The Bluetooth connection was easy to make and works well. No problem making or maintaining the Bluetooth connection.NEGATIVES:1. I like to keep track of my heart rate, and while the screen does show the heart rate on the different exercise routines, the heartbeat readout is very small, whereas it is much larger and easier to see on the Fitbit. It is not easy to see without having to bring the watch closer to you. On a personal level this is probably the biggest complaint I have with the watch, although it would not stop me from buying it. If Tozo sees this review I hope they will consider increasing the size of the heartbeat readout, since it appears that there is plenty of room to do that.2. There is no GPS. I am listing this as a negative here only because this could be an issue for some people who are walking outside and want an accurate distance calculation beyond what the watch can do on its own. The Fitbit does have GPS. Of course, Iâm sure that is one of the things that accounts for the big difference in price. For me the lack of GPS is not an issue at all, since my exercise is all done indoors. If that is your situation, then you would just be paying for something you donât really need with the Fitbit.3. The Fitbit has a read out that shows what they call âActive Zone Minutesâ, which takes into account your heartbeat level to determine how good a workout you are getting. I like that because I can tell at a glance how good a workout. While the Tozo does show you what percentage of time you spent in each heart rate zone, it doesnât have this additional calculation to show you a combined score using what Fitbit calls their âActive Zone Minuteâ readout. While this is certainly not a dealbreaker by any means, this would be a great addition to the Tozo if they could do it.I donât want to put this as a positive or negative, but potential purchasers with small wrists should be aware that the watch is fairly large. That, or course, is a positive in terms of the amount of information you can put on the screen, but if you have small wrists (like I do) you might want to consider one of the smaller Tozo smart watches if you plan to wear this all day. I only wear the watch when I am exercising, so itâs not an issue for me, and I like having the larger screen. The watch and the band are both comfortable. Just something to keep in mind if you have small wrists.Overall I think this watch is an incredible value. I donât know how they can put out a smartwatch this good at this price. As long as you donât need GPS I would certainly recommend giving this watch a try. I have been impressed with Tozoâs earbuds, and what I found with this smartwatch is consistent with that. I recommend this product highly.

This is a great smart watch. I’ve had others that have a great battery life but wear out too quickly. This watch is right in the middle of battery life, and very resistant to wear and tear with more abilities. They chose to use better materials for sure. The silicone band is actually better quality than any silicone bands I have tried before. I choose not to use every app function to find a nice middle of battery life. I get over ten days of battery, and more like 20.Two things I wish was different is that the alarm count is only five. All my other apple watch alternatives allow for 10 alarms to be set. I think that should be added in an update. The second thing I didn’t like is that the watch would use a flashing green light sensor when sensing my waking up in the morning before I was actually up. The light would flash and wake me and my spouse up. I would prefer the sleep detection wake up sense function to not use bright lights that peak through any gap of my wrist and watch.The last thing I have been used to is being able to wake the watch up, but then click the button to sleep the screen. My watch does not let me sleep the screen after I check the time. It would be nice to when its early morning and can quickly shut the bright screen down.All in all I would use this watch in spite of these few little things. Plus I think Tozo would care to make changes in updates. I think this watch is great on a budget of a watch that can do a lot of useful health monitoring, app functions, and durability.Update. Ive had the watch for almost a year and still love it. They have made good firmware updates and app updates that help maximize functionality. Still want updates for sleeping the screen, more alarms than 5, and a calculator. Another issue is that if my watch is connected to my phone and I go to use speak to text. It will randomly only use my phone and the watch makes an odd beep noise. It is not consistent when it chooses to do this. It is still hands down the best watch before paying more for apple or other smart watches at a much higher bracket. I don’t worry about this watch with rough work. It keeps on going and looks almost like the day I got it. You wont be disappointed. The company has great customer service as well!

Because there are so many reviews about the functions and finish of this product, I want to review a function which is not described by other reviews.Recently, I started running with GPS of my mobile, but it has been always painful to take out my mobile to start and stop GPS tracking. So I started looking for a smart watch to start and stop GPS tracking function of my running app.I did some search and I found that there is a smart watch from TOZO. I could see a few reviews from Youtube, but there are no reviews if this S3 can start / stop GPS tracking. So I was not sure, but I gave it a try. And to my surprise, this watch can start / stop GPS tracking of my mobile! So I did some quick check with the app and indeed, TOZO app could save GPS information. This is exactly what I have been looking for. It also saves other information like heart rate, pace or etc. And it also has a function to export the data to Strava platform.At this moment, I don’t understand why TOZO doesn’t advertise this feature more aggressively. If you want to start running with a limited budget, try this TOZO product.PS 1. Of course, I’m happy with other functions too. But like I said, I will save my talk because there are other reviews too.PS 2. I saved my own information from the photos to protect my privacy.
