  • Terrific smartwatch and an amazing value
Color: Black
I have been a customer for several of Tozo’s 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 I’m 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. It’s 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, I’m 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 don’t really need with the Fitbit. 3. The Fitbit has a read out that shows what they call “Active Zone Minutes”, 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 doesn’t have this additional calculation to show you a combined score using what Fitbit calls their “Active Zone Minute” 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 don’t 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 it’s 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 don’t know how they can put out a smartwatch this good at this price. As long as you don’t need GPS I would certainly recommend giving this watch a try. I have been impressed with Tozo’s earbuds, and what I found with this smartwatch is consistent with that. I recommend this product highly. ... show more

  • GREAT Product!!
Color: Black
I have had this watch since December 28th and wanted to wear/use it a bit before posting a review. Today is January 11th so I've had some time to really see what it's made of. That being said, i cannot say enough great things about this watch. Of course the price is AMAZING but so are all the features! You you can call AND talk through iy as well as send quick reply texts and receive / monitor all messages and selected app alerts. The health features are great as well, from the step counter to my favorite the sleep monitor. It is super comfortable to wear and I literally have barely taken it off since receiving it and that goes for at night/ sleeping with it! There are a ton of different style watch faces to choose from right from the app, no having to download something every time you want to change it. All the features work great, it wears great and I couldn't be more satisfied unless it was free!! I'd be careful with the band as the pins used to attach the band are small and a bit delicate so this is not the watch you'd want if you work hard with your hands, etc. It would still be great buy you may be replacing the band. I would suggest a more rugged/industrial style smart watch. Also, if you have larger wrists this may be a bit small for you. I'm 6'3 and 215 lbs just to give you an example and I can only put it on the next to last watch banf hole. It is still comfortable though and I wear it constantly. Over all this an EXCELLENT watch at an AMAZING price with a TON of AWESOME features. If I could give it ten stars I would!!!!! ... show more

  • Great value for a budget smartwatch!
Color: Black
This is my first experience with a smartwatch, so I can’t make any comparisons to other popular smartwatches. But with that said, I can tell you that the S3 has quite a bit to offer for the price, but in my review I’m only going to touch on the features and apps that were most useful to me after using the S3 for a couple of weeks. 𝗣𝗿𝗼𝘀 • Price: About $50.00 or less if you catch it on sale (a fraction of what you’ll pay for a smartwatch from Apple, Samsung, Fitbit, etc.). • Fairly easy to use with a variety of built-in apps. • Comfortable to wear. • Very good battery life. 𝗖𝗼𝗻𝘀 • The companion app for Android & IOS needs improvement. • Minor functionality issues with some of the apps. 𝗚𝗲𝘁𝘁𝗶𝗻𝗴 𝗦𝘁𝗮𝗿𝘁𝗲𝗱: The S3 comes packaged in an attractive box and includes a watch strap, charging cable, and a small, printed user manual. The printed manual will prompt you to install the companion app (Tozo Health) on your mobile device where you are stepped through a setup routine that is pretty straightforward: creating an account for Tozo Health, pairing the S3 with your device, and entering your physical stats (i.e. height, weight, and age) – this data is used as a basis for some of the included watch apps. I had no problems paring the watch with my Samsung phone. 𝗛𝗮𝗿𝗱𝘄𝗮𝗿𝗲: Overall the build quality seems good: the watch is mostly plastic although I’m not certain about the watch crystal covering the screen (it could be glass or a high-quality acrylic material). The watch strap appears to be made of a soft, rubber-like material that was comfortable on my wrist (I could wear the watch for hours at a time without it becoming uncomfortable) – I also appreciated that the strap pins have these little protrusions that allow you to retract the pins with your fingers for inserting the strap into the watch itself (no need to use a knife or a spring bar tool – a very nice touch). I also appreciate that the watch is waterproof (“IP68 waterproof” according to the online product description) as I sweat profusely when exercising (especially outdoors in the Central Texas heat)! The S3’s screen can be controlled by touch and is quite responsive. The watch crown also has some functionality when you press it, although it does not appear to do anything when you twist it around (at least not in my experience – perhaps this will change with future updates). I also found the screen to be bright enough for viewing outside in bright daylight. The S3 comes with a charging cable that is different from anything else I’ve seen before: one end plugs into a standard USB socket (computer or USB charger) and the other end connects to the bottom of the watch via two metal contact points that are held in place with tiny magnets on the end of the charging cable. I’m not sure why Tozo went this route instead of using a standard USB-C connector – my concern here is that if the charging cable fails then you will have to obviously obtain another one from Tozo. In any case, I didn’t have any issues charging the watch with this cable and it didn’t take very long to get a full charge which lasted well over a week (with a mix of casual usage and running the exercising apps) before needing to charge it again. 𝗪𝗮𝘁𝗰𝗵 𝗔𝗽𝗽𝘀: The S3 has built in apps for various exercise routines, health monitoring (e.g. heart rate, oxygen, sleep, stress level), weather, music playback on your mobile phone, making calls on your mobile phone and viewing text messages/notifications, and other utility apps (such as an alarm, timer, and stopwatch). There is also a “Find Phone” feature that will ring your phone in case you misplaced it, but this only works if the Tozo Health app is running on the phone, so it may only always be useful. A calculator app would have been nice to have. Oh, and did I mention that the S3 also functions as a wrist watch? 😊 I do a lot of walking (both indoors and outdoors), so the apps for these activities were the ones that I used the most. When walking or running, the S3 will calculate and record your steps, calories burned, distance, average pace, average heart rate, and other metrics as well. When used outdoors with the Tozo Health app it should show you your location (based on GPS data) when the app is configured to use Google maps, but I just couldn’t get this feature to work even when giving the app all the permissions it required on my phone. If you choose not to take your phone with you while walking or running then the watch will still display and record your exercise data then later sync this data with your phone automatically when you reopen the app. Interestingly, I found that the outdoor walking app seems to overcalculate my steps. I tested this several times by walking to my neighborhood mailbox which is about 210 steps one way from the front door of my house (about 420 steps round trip, give or take a couple of steps). The watch consistently calculated this anywhere between 450 and 460 steps. My guess is that the S3 is calculating an average step size based on my physical height that I entered when setting up the watch. I tend to take larger-than-average steps when walking, so perhaps that is accounting for the difference. I also noticed that the watch didn’t seem to accurately monitor my activity when walking on my treadmill – I couldn’t figure this out until I read the following in the manual: “when doing outdoor sports without continuous arm swing , such as riding, please turn on the exercise interface in the app, which will record your exercise data more accurately”. So I take this to mean that the watch relies on detecting arm movement when walking or running – this is a problem for me because I always keep my arms stationary on the treadmill handrails, but the solution provided in the manual does seem to work as described, so overall this is just a minor gripe. The music control app worked fine for me but not with every music app that I tested on my phone (the S3 was able to control two of the three music player apps that I have installed). And using the phone call app on the S3 was a mixed bag: I was able to answer incoming calls using the watch and initiate outgoing calls using the dial keypad on the watch, but I could not initiate outgoing calls when selecting any of the 10 contacts that I imported into the watch from my phone (the S3 would act like it was dialing the contact but would then quit and go back to the contact list). I really liked the heart rate monitor and it seems fairly accurate (I tested this against taking my own pulse manually) and the watch will give you a constant average heart rate while exercising – very useful to ensure that you don’t go over your max heart rate for your age. 𝗖𝘂𝘀𝘁𝗼𝗺𝗶𝘇𝗮𝘁𝗶𝗼𝗻: My favorite option here were the watch faces that you can display on the S3. There are several built into the watch that you can instantly switch between as well as many others that you can import from the Tozo Health app, however, I was disappointed that the S3 only seems to allow you to retain one imported watch face from the app (i.e. it only seems to keep the last watch face that you import). I would like to see this improved as well as having more watch faces added to the app (animated watch faces would be nice). 𝗖𝗼𝗻𝗰𝗹𝘂𝘀𝗶𝗼𝗻: Overall I really like the S3 (especially at its price point) and have no problems recommending it as a budget smartwatch, but there is room for improvement and some bugs to be worked out, especially with the companion app since the S3 relies heavily on it. I’m hoping that Tozo continues to develop its line of smartwatches which I think are a great value. 𝗨𝗣𝗗𝗔𝗧𝗘 𝟬𝟵-𝟭𝟲-𝟮𝟯: I recently noticed that an update for the Tozo Health app was available in the Google Play store, so I installed it and found that the Google map feature now works in the app when walking or running outdoors. I still cannot make outgoing calls on my phone using the contacts that I imported into the watch, but at least it seems that Tozo is being responsive to updating the app, so I'm hopeful that some of these other minor quirks will be worked out in future updates. ... show more
