I recently stumbled upon a hidden gem in the world of smartwatches, and I couldn’t wait to share my excitement! The Tozo S4 is an absolute game-changer, combining a budget-friendly price tag with a plethora of modern features that left me in awe.First and foremost, let’s talk about the incredible value for money. I was pleasantly surprised by the affordable price of this smartwatch, especially considering the extensive list of features it boasts. It’s proof that cutting-edge technology doesn’t have to break the bank.The design of the smartwatch is sleek and stylish, making it suitable for any occasion. The vibrant and responsive touchscreen provides a seamless user experience, and the customizable watch faces add a personal touch. I’ve received numerous compliments on its appearance, and people are always shocked when they find out how reasonably priced it is.But what truly sets this smartwatch apart is its impressive array of features. From heart rate monitoring and sleep tracking to GPS navigation and call notifications, it covers all the essentials and more. The built-in fitness tracker has motivated me to stay active and maintain a healthier lifestyle. I also love the convenience of receiving notifications directly on my wrist, allowing me to stay connected without constantly checking my phone.Battery life is another standout feature. I was amazed at how long the smartwatch lasts on a single charge, making it a reliable companion for daily use over an entire week without recharge! Whether I’m tracking my workouts, receiving notifications, or simply using it as a stylish timepiece, the battery life never fails to impress.Setting up the smartwatch was a breeze, thanks to the user-friendly interface and clear instructions. It seamlessly syncs with my smartphone, and the dedicated app provides detailed insights into my health and fitness data. The Bluetooth connectivity is stable, ensuring a smooth and uninterrupted experience.In conclusion, the Tozo S4 has exceeded my expectations in every way. It’s the perfect blend of affordability, style, and functionality. If you’re in the market for a budget-friendly smartwatch with a wealth of modern features, look no further. This incredible device has truly redefined what’s possible in the world of affordable wearable technology. I wholeheartedly recommend it to anyone seeking unbeatable value without compromising on quality!

For years I resisted getting myself a smart watch because I didn’t think I would need it, use it, or like it. That all changed when I was gifted a Tozo S3 two months ago and tried it out. WOW! What a game changer it turned out to be for me. I never realized just how useful I would find it to be and how much I would love it. Fast forward 2 months later and I have gifted the S3 to my elderly mom, so she can wear it when she goes out on her evening walks with her dog. She’s a fitness fanatic so she finds all of the exercise tracking feature super useful, but in addition to that, I felt compelled to have her wear it for safety purposes. I love that the 1-touch phone 📞 option on the watch dial affords her the ability to make an emergency 🆘 call so much quicker and easier than using her smart phone. That’s peace of mind for me! It also allowed me to personally upgrade my smartwatch to the dazzling S4 which I LOVE 💕 !! You can think of this upgrade similar to an iPhone upgrade where you immediately notice a faster processor, dramatically improved color visuals and graphics on the AMOLED screen (which geeks like me live for!), better phone call quality, extended battery life, able to read text messages quicker and easier, and a lot more. There are other upgrades that I won’t go into detailbecause your own user behavior and your specific preferences will dictate which upgrades are useful or significant for you. The combination of Tozo’s affordability, relative to other comparable products, combined with their amazing quality and customer service is why I keep buying their products with confidence. This is another big winner for me!

Great smartwatch! Love the Tozo products. We have several of their headphones and the smartwatch has not disappointed. It’s a great price and value. I compared functions of other smart watches and the functions on this are very comparable while saving a ton of money. The screen is very responsive to touch and movement. The colors are vibrant. The health functions are working. It tracks steps, oxygen levels, heart rate, and monitors sleep patterns. I like how it has a wide variety of great looking watch faces. You can even add your own picture to be one of the watch faces. Battery life is good and you can change the settings to save battery or use more (ie – brightness levels, etc). It just depends on how you use the watch. The app on the phone is great and connects easily to the watch (see screenshot).The call functions work great. I have received calls through the watch and I am able to talk and hear through the watch. The speaker is decent. I have also spoken into the watch for some google assistant things. Sometimes that is inconsistent. It allows media controls (pause, skip, etc) which is helpful if running or exercising with the watch. The clock functions have a timer and stopwatch. I also like choosing from the app, which app notifications on my phone to display on the app. As far as I can tell for text messages, you can only view the texts and not reply from the phone. But I’m fine with that as I don’t want to try to type on the phone anyway. It’s just nice to see what notifications are pinging me without having to pull out the phone.A few things Tozo could improve….It would be helpful if the time and stop watch could run in the background. You have to stay on those screens for them to run. The world clock allows you to add up to 5 cities. Again, an improvement for Tozo would be to add more cities in the search for world times. While the multitude of watch faces is nice, I haven’t figured out how to change out the 4 preset faces that are stored on the watch that you can rotate through. It only lets me add and change the 5th preset. It would be nice if I could choose all 5.Other than those few things, I am very happy. I have been testing this for a week now pretty heavily. I am very happy.

I’m a spreadsheet guy, to a fault, and my wife regularly talks dirty to me by asking me to compare products for her. When my most recent smartwatch finally crapped out on me after 2.5 years (Mobvoi TicWatch 3 GPS), I waited to see what was going to pop up on my radar so that I could get started on my next spreadsheet journey. I am firmly entrenched in the Google ecosystem so it was going to be either the TicWatch 5 or the Pixel Watch 2… but neither of them were really what I wanted. The TW5 is bulky and expensive and the PW2 is too small… and, also, expensive. I knew there had to be a budget smartwatch on Amazon that could get the job done until the next TW and/or PW came out so I started looking. I stumbled on this one, the S4, because I recognized Tozo as a maker of premium quality yet budget-friendly earbuds. So, I took the leap and here’s my review after 10 days.Battery life:When you unbox your watch, there’s a sticker on the face that advises you to fully charge the watch prior to turning it on and using it. I connected the charger and the watch was already at 94%, so I turned it on and let it rip. That was last Tuesday afternoon (January 9, 2024); my watch died sometime in the middle of the night this past Tuesday morning (January 16, 2024) between 2300 and 0630. When I went to bed it was still at 9%. My TW, initially, held strong at about 48 hours before it needed to charge and, eventually, it trickled down to about 7 hours right before it died. This thing does exactly what I expect it to, which is to simply notify me of calls, texts and emails, just like my TW did, and it lasted 7 days strong on one charge. Also, from totally dead to 100% battery only took about 75 minutes. I am very happy about this. *5/5UPDATE 01/28/24: I have had this watch for almost three weeks and I just charged it for the THIRD TIME today. Changing my battery life grade by giving it +1, so it is now *6 / 5.Accessories:The charging cable that the watch comes with is proprietary (bummer) and measures about 24.5 inches (WTF?). It is remarkably short. For comparison, the Mobvoi charger that my TW came with measures just shy of 36 inches. Additionally, the magnets that keep the charger attached to the watch are laughably weak. I could pick my TW up by the charging cable when it was attached and I couldn’t even MOVE the S4 itself while the charger was connected because the magnets aren’t strong enough to keep it in the right spot. *1/5, a one (1) only because they include the cable in the box, otherwise it would be zero (0). Continue reading to learn about the watch band…Comfort:The S4 comes with a high-quality silicone band with “Tozo” stamped on it. It’s very similar to what you might see on an Apple Watch, down to the band overlap going under the band to get out of the way. The watch itself, however, isn’t the most comfortable on the wrist and sits kind of weird, most likely due to how large it is. It is noticeably lighter than the TW3 though (for those of you who have one, or who were wondering), coming in at 1.4 oz compared to 2.3 oz (almost 40% lighter). *3.5/5Screen:The 1.78” AMOLED on this thing is bright – like BRIGHT bright. Luckily, it has 5 brightness settings that you can easily select from, either directly on the watch or in the accompanying app. You can also change the screen time-out intervals in increments of 5 seconds, from 5 seconds up to 30 seconds. The colors aren’t oversaturated and they’re quite crisp. You can also turn on Do-Not-Disturb and/or Silent Mode at night to keep it from making noise when it’s quiet. There really isn’t anything to complain about here. *5/5Watch faces:The advert describes 100+ watch faces and as of right now (01/19/2024), there are a total of 246 – 3 of which are “custom,” meaning you can use a photo of your choosing as the background. The other 243 fall into categories titled, “Simple,” “Personality,” “Colorful,” “Pointer,” “Business Style,” and “Festival.” The sheer number is a bit overwhelming, but then again, so are most of the watch faces. It’s a WYSIWYG shop here: there are no customizable complications and the vast majority of the faces are either distractingly colorful or needlessly busy. The one that I’m currently using, called “Intelligence – Future,” has a comparatively subdued black and blue color scheme but there are some confusing inclusions and omissions. For example: there’s a battery icon at the top right of the screen but there’s also a battery percent reading in the face. Additionally, there are three placeholders for complications; two of them are in use (the previously mentioned battery percentage and heart rate) but the one in between them is empty. Again, there’s no way to select a complication to place there… it’s just a black circle. One of the most frustrating aspects of this watch so far (which is relative, of course) is that there is no option to make your own face or modify the ones that are in the Dial Center. I’ve searched far and wide to see if any savvy devs out there have figured out how to jack into this OS, or even knows what type of OS this thing runs, but so far it seems like no one has had any luck. Hey Tozo – give us a watch builder or at least the option to add/modify complications! *3/5Processor and OS:Tozo advertises the S4 as having a “high-precision wear chip,” but there doesn’t seem to be any indication of what type of chip is actually running the watch. The same goes with the OS – my assumption is that it’s some kind of RToS, similar to what the One Plus Watch runs/ran, which explains how/why it’s so responsive. Honestly though, it doesn’t really matter because it’s snappy and rarely stutters in day-to-day use. *5/5Intelligent Message Notification:Coming from a WearOS device, I guess I was accustomed to a more robust notification system. Not that the S4 is lacking, because it will definitely let you know when you’ve received a message or email or phone call, but not being able to respond directly from the watch is kind of a bummer. It’s definitely not a deal breaker, but it would be nice to be able to use an on-screen keyboard or voice-to-text to quickly reply to texts and instant messages. In the Tozo Health app, you can create a few canned responses if you decline a call but they can’t be used to respond to any other type of communication. Additionally, you need to be sure to go into the Notification and Reminders section of the app, select “App messages,” then manually select which apps you give permission to notify you otherwise you’ll likely miss them until the next time you look at your phone. Another aspect that took some getting used to is the notification icons that the watch uses. It recognizes FB Messenger and shows the blue bolt-looking thing; it also recognizes Outlook and shows the blue email icon, but it uses a generic one for text messages that looks like a 4-leaf clover. This is just me being picky, I suppose. The main factor to remember here is that this thing concurrently notifies you when notifications come in. My watch vibrates, literally, at the same time as my phone. Also, the vibration motor in this thing is SUPER strong so you will definitely know when it’s going off. I couldn’t say that about my TW. *4/5Bluetooth Calling:I’ve only used this feature once so far, and it didn’t sound great (the caller’s voice was tinny and distant), but I was outside and the ambient noise level was pretty high. Obviously, this isn’t going to replace a BT or wired headset, or the speakerphone on your device – but to answer a call in a pinch until you can get to your phone, it is totally passable. You can add up to 10 frequent contacts in the app which will sync to your watch so that you can initiate a call if your phone is close by but out of reach. That’s a pretty cool feature that I don’t recall my TW having. *4/5Fitness Features:Gonna be totally honest – I didn’t buy this watch for the fitness features so I haven’t tested them, nor do I suspect that they would be accurate anyways. Standard on the watch, when swiping right to left, are the HR monitor, Sleep monitor, Stress monitor, Weather screen, and Activity monitor. Based on the comfort of the watch, I’m not interested in wearing it to bed to test the sleep monitor nor would I trust it to keep track of my HR. *X/XSoftware quirks: Some of the stranger software quirks that I’ve noticed so far are…*The rotating crown employs a satisfying mechanical haptic “bump” when you rotate it, and it does a serviceable job of assisting with menu and screen navigation but when the display is on, rotating the crown will cycle through the five watch faces that live on the device. So, if you’re wearing a long sleeve shirt, sweatshirt, or have short hands and put them in your pockets, you may inadvertently swap your watch face. I’ve done it a few times and it’s becoming quite annoying.*The screen has to stay on, and on the timer module, for the timer function to continue counting down. I recently set a timer for 5 minutes then clicked on the crown to return to the home screen and went about my business. It took me quite some time to realize that the timer should have gone off long before then and when I went back into my watch, the timer had reset / the function ended.Overall: For the price, and the features, I couldn’t be more pleased with this purchase. The S4 does exactly what I need it to, which is to help me keep my eyes off of my phone – and tell me the time every once in a while. It’s taken a little getting used to the shape (i.e., rectangular [APPLE – BARF!!!] vs circular [Google – HOORAY!!]) but, to be honest, it works much better for reading notifications and not having to worry about square notifications getting cut off by round bezels. The battery life is INSANE, the screen looks great, and it stays connected to my phone consistently. Anyone looking for a high-quality, budget smartwatch, should definitely consider this one.

The TOZO S4 AcuFit One Smart Watch was purchased to replace a FitBit Sense (purchased in Jan ’22 and still works fine). I have had several FitBits over the years and the community aspect was great in the beginning but my friends and co-workers have not kept up with the FitBit challenges amongst ourselves. Additionally, Google purchased FitBit and online account features have changed. Rather than stay within the FitBit community, I opted to try the TOZO S4 with TOZO’s free Health app installed on my Android phone. The $60 price is much, much less than current FitBit offerings though there are not additional purchases available for screen protectors, watch bands, and charging cable. Watch band and charging cable replacements were a necessity as long term use wore out these FitBit items. A charging cable could be requested if still under warranty. I have only had the S4 a short time so I cannot comment on its long term use. The screen itself is brighter and I appreciate the old school watch crown to cycle through watch face themes. There are more theme options to select under the Dial Center in the TOZO Health app. Not as many selections as FitBit but I’m also not seeing them cost money as some of the user submitted ones with FitBit do. Enough with FitBit comparisons. For BOTH the S4 and the Health app, I am enjoying the fresh, stats heavy displays of information. On the S4, it is focused on current day with high, low, average, and charting for that day. On the Health app, the daily historical data is saved and reported with options to review by day, week, and month along with general information on normal ranges and tips. I am hoping to spend some time reviewing MY data but I hadn’t taken much interest in the past with the Fitbit and it’s app so we will see if I become interested. I am curious about the Stress dataset, what it is measuring, and how I can improve that metric! If you don’t have or need a set of friends to challenge with steps, etc., the TOZO S4 is a solid, nice looking, stats heavy, watch to track and, hopefully, improve your health with. Enjoy!
