A Great Smart Watch!
This is a really nice watch for a very reasonable price. Before writing this review I played around with it for five days and tried out just about every function it has. They all work. All you need to do is give it all the permissions that it requests. There’s a page in the app that you download on your phone that requests permissions. I was initially concerned that allowing it to constantly run in the background of my phone would drain my battery, and the app said that was a possibiity, but I noticed no difference in my phone’s battery function. In fact, it used only 6% of the battery. Setting it up the first time was a little confusing. There was one screen that had a button that should have taken me to my phone’s settings and it didn’t work. I tapped the “ignore” button to get out of the screen and went to settings myself. The problem is that every phone’s settings are different. I have a Samsung S23. My husband has a Samsung S24. The settings are completely different. So it’s really impossible to provide instructions that will be accurate on every phone. One last tip is that when you get to the point where you’re setting up your profile (gender, height, weight, etc) the button you need to tap to proceed to the next screen is in the center at the bottom of the screen. It’s very light. If you don’t know it’s there, you won’t see it. You are also given the option to set it up for metric or imperial measurements. Once you get through the initial setup, everything works great. Like I said in the first paragraph, just give it all the permissions it wants and it will work great for you. Now the fun stuff. I guess I’ll start with the appearance. It came in a very attractive box which would make for a very nice Christmas gift. The watch has 440 watch faces! I took screenshots from the app of some of them to give you an idea of what’s available. With that many watch faces you have to be able to find something you like. You can also customize watch faces if you like. It comes with two different styles of watchband. Both are silicone, one has a normal watchband buckle and the other allows you to tuck the excess band between the watchband and your arm. The band size is 20mm so if you want to purchase different watchbands you can. Regarding the functionality, first I want to remind you that it’s connected to your phone via bluetooth so you have to keep your phone near your watch, otherwise the connection will be broken. If that happens, the watch vibrates and the dial displays a message indicating that you’ve lost the connection. As soon as you are back within range of your phone it automatically reconnects. I found that notification feature to be useful in preventing me from leaving my house without my phone. I’ve done that a few times in the past and it’s very inconvenient. This watch will make sure you don’t do that. The watch has so many functions that there’s no way I can describe, or even list, all of them. I took a lot of pictures, though, so you can see for yourself what functions are available and what they look like on the watch face and your phone. I will discuss a few, though. You can set it up to receive all your text messages as well as notifications from social media apps like FB, Messenger, WhatsApp, Nextdoor and more. Other apps you can receive notifications from include Instagram, YouTube, Gmail, Snapchat, X and Pinterest. That list is probably not all inclusive. I tested the text message function as well as the four social media apps I just mentioned and the watch did not miss a single notification. 100% accuracy for five days! You can also answer your phone using the watch. I had my husband call me and I was able to answer the phone and speak to him through the watch while my phone was in my pocket. He said my voice came across crystal clear! I was also able to make phone calls using the watch. I didn’t import my contacts because I have a lot of them. I just dialed my husband because I know his number by heart. The speaker on the watch works very well. I set seven different alarms just to test how many it would allow me to set and I can safely say you can set at least seven to go off every day. I got bored after that and didn’t try to set up anymore alarms. I doubt anyone would need to set up more. The alarm goes off whether you are wearing the watch or charging it and it’s loud enough for you to hear. It’s a really nice function. The sleep monitoring function is my favorite. It shows on the watch and your phone. I’ve included photos of both. It also records your heart rate, blood oxygen record, stress record, emotion record, steps, calories burned and kilometers covered. It can be personalized to record for may different kinds of exercises including but not limited to pushups, situps, gymnastics, tennis, walking and running. It also provides weather reports as well as two different games. Like any new device you’ll have to play around with it to get used to it and to discover all the functionality it has to offer. You can swipe up, down, right and left to get to different menus. I’m very happy with this watch. It has so much more functionality that watches that cost much more and it’s even waterproof. You can’t go wrong with this watch. I really think you’ll love it.

Watch is nice and came fast !
Smartwatch Review: A Perfect Blend of Style and Functionality The Smartwatch has exceeded my expectations in every way. It strikes a perfect balance between sleek design, robust functionality, and impressive performance. Here’s why I absolutely recommend it: Design and Build The watch boasts a modern, minimalist design that complements any outfit. The high-resolution AMOLED display is vibrant and responsive, making it a joy to navigate through apps and notifications. Its lightweight build ensures comfort during all-day wear, while the durable materials make it sturdy enough for active lifestyles. Performance and Features This smartwatch is a powerhouse of features. The fitness tracking options are comprehensive, offering metrics like heart rate, sleep quality, blood oxygen levels, and even stress monitoring. The GPS tracking is accurate, making it ideal for runners and outdoor enthusiasts. I was particularly impressed by its seamless integration with my smartphone. Notifications, calls, and texts are easy to manage, and the voice assistant feature works like a charm. The watch also supports a wide array of third-party apps, enhancing its versatility. Battery Life One of the standout features is the battery life. It comfortably lasts 4–5 days on a single charge, even with moderate use of GPS and other features. The fast-charging capability is a lifesaver when you’re in a rush. Customizability From interchangeable bands to customizable watch faces, this smartwatch allows plenty of personalization, making it truly your own. Conclusion The Smartwatch is more than just a timepiece—it’s a personal assistant, fitness coach, and style statement all in one. Whether you’re a tech enthusiast, fitness buff, or someone looking for a reliable smartwatch, this device is a fantastic choice. Highly recommended! Rating: ★★★★★

The battery lasts me a full week on 1 charge!
I wanted a watch that would look nice on my small wrists, be comfortable to wear, and from which I could make a call if needed. And tracking my steps and my sleep. This fits my wrists, with a nice size that doesn't look too large, and it is so lightweight and comfortable to wear that I forget I even have it on! Looks? It said the band was gray in the description. To me, it's a warmer tone, more like an oatmeal color, and I think it's perfect with the gold! I'm super happy with the fit and the look! It comes with 2 bands, each a little different in style and the way the band fits under itself or on top with the loop. I had missed that myself. I love the one that fits underneath on my wrist, like my Samsung watch did. I have yet to try the other! They are both the same color. It has a variety of watch faces to choose from, and I found what I liked. It connected to my Samsung phone easily, and the app is pretty simple. I've tested both making and receiving calls, and both work great! It has many different sports to choose from, but as I said, I only need something to track my steps, treadmill walks, and my sleep. It also reminds me to get up and move sometimes. It seems to be accurate. The only thing I've disliked so far is the tone of the ring or notification. It has a tinn sound. I know I'm a bit picky but I didn't care for that. So I turned off the sound. I deducted 1 star for that reason. The #1 most favorite part for me, besides the look, fit and comfort? The battery lasts me a week! I don't have to even think about charging it for a week, and it's so refreshing! I had a Samsung watch, which I loved, but I didn't love having to charge it every day! This watch was a great value on sale! All things considered, I think it's a great watch for someone who needs certain things from a smartwatch and has a limited budget. To only have to charge it 1x a week is amazing! Yet I don't call from it or use other features that others may use. I gave it 4 stars!

Great Product!
I recently purchased this Keeponfit smart watch, and it truly impressed me. First, it was charged and ready to go when I unboxed it, and the app was easy to download. It linked to my phone via Bluetooth with no issues, and all of its features work exceptionally well and intuitive to navigate. I have had a lot of difficulty with heart rate monitors on other smartwatches, but this one is able to measure it accurately and provide useful data. There’s also a built-in pedometer and several workout modes that track information about different physical activities. I was also easily able to personalize the watch face and the notifications it sends me. I receive calls, texts, and app alerts on my wrist, which saves me from having to find my phone or log onto my computer when I’m busy. (It can also help me locate my phone, which is super handy because I’m always losing it!) Even with all the activity from the features I use consistently, the battery keeps its charge for an impressive amount of time. I can forget to charge it overnight and still have power in the morning. Speaking of sleep, I was excited about its sleep monitoring function because I have sleep issues. It can help me figure out how much sleep I am getting and log helpful information for my doctor. However, this is the only feature I have not yet figured out. I’m sure this has nothing to do with the design of the watch, ‘cause I’m old and can’t always figure out new technology without help! My daughter returned home recently after being away for several weeks, and I’m sure she will be able to help me figure out what I’m doing wrong. (She also told me she is jealous I have it because of its trendy style. This is a huge compliment because she is rarely impressed by what I wear lol) Overall, it’s a great watch at a fantastic price. I have absolutely no complaints and am happy I bought it. AND it came with two different watch bands! (I love having choices :)

lightweight, comfy and pretty accurate.
It is so comfy that I could sleep with it without feeling it, sleep tracking seemed to be very accurate compared to my Gear 6, Heart rate also matched my Samsung watch, Oxygen Saturation might be a bit iffy but mostly due to being in movement, the sound is incredibly good, call clarity is actually way better than my Samsung 6 watch to my surprise, I could talk without even aiming my voice to the watch and the person receiving the call was not even aware I was on my watch until I let him know. The app is very easy to use and understand if you ever had a smartwatch before, it is also very simple. 2 things I do not like about it: 1st there is no always on display (easily added with a firmware update), 2nd the watch faces are not stored on the watch, after you selected one that you like, there is a lot of them to chose from, it will be used on the watch, but as soon as you change it for another one it will be forgotten and if you want to use it again, you have to install t again from the app, it is saved on your used watch faces, but it takes a few seconds to upload to watch every time. Conclusion: extremely capable watch for the price, so comfortable you can wear it to sleep and will not be bother by it, material is very smooth and will not make your wrist sweat. if you want a decent smartwatch and not willing to shell $200 plus for a brand name one, you can not go wrong with this one, if they add the always on display with an update, this watch will be 6 stars for its price and capabilities.

Worked only one month.
UPDATE: The return window closed 3 days ago and the watch no longer works at all. There is no damage and it wasn’t dropped. Lasted only a couple days past one month. First, I truly adore the look of this watch. It looks great with casual to dressy outfits. I purchased it to find out if I want to invest a lot more into a smart watch. I wanted to find out if I am a smart watch person. I found out I am. Second, a few of the main reasons I want a smart watch are to keep up with my fitness. It does a good job of that. But, I also want to be able to review my incoming texts while I am at work and can’t look at my phone to find out if one of my children needs me. If so, I’ll break protocol and get to my phone ASAP. They are my priority. One other reason is to locate my phone. I misplace it frequently. Unfortunately, the watch frequently unpairs with my phone so those two features aren’t dependable. I truly need them to be. Out of the last 4 times I’ve needed to find my phone, it was connected only one time. That is frustrating. But, I have learned I do want a smart watch while using this entry level watch.

If you want functionality and reliability as a smart watch, this isn't it
PROS: +works fine as a fitness tracker CONS: -only compatible with a limited amount of apps for push notification purposes. No way to add preferred apps. -unreliable connectivity, does not notify of disconnect. VERY big deal, if you are relying on this watch as an extension of your smartphone for time-sensitive communication notification purposes (I paid for this very dearly when I missed a critical, time sensitive message. Lesson learned). -unclear instructions, does not use universal icons, especially RE basic function (case in point: no bluetooth icon on watch for easy pairing. Where is it? Instructions do not indicate. Finally found under the "phone" icon in the watch menu, the last option on the menu, under the unlocked padlock icon labelled "switch" (why did they put it there??? Not very clear or accessible, for a feature that is so essential for the functioning of a smartwatch, and one that needs to be accessed SO OFTEN). As a side note, the English language in the instructions, watch, and app are not translated very well, which can add to the confusion. -Bluetooth range on this watch is not great. Like, the next room over is too far, and if the watch disconnects, not only will it NOT notify you, you'll have to reconnect it manually when you realize it's disconnected (and hopefully you weren't relying on your watch for critical communications the whole time it was disconnected- uh oh, *panics* better check). CONCLUSION: For a fitness tracker, it's great. For a smartwatch, it's not, at all. If you need functionality and reliability, this isn't it.

Pretty watch, but buy a fitness tracker if that’s what you’re looking for
Let me start by saying that I don’t have a lot of needs from my watch. I need to be able to tell time, count steps, and track my heart rate. For that purpose, it’s a good watch. It would be nice to record my workouts, but this watch and corresponding app aren’t very good for that function. The data doesn’t translate to the app in any way that’s useful. However, I’ve had the watch for a few months and I suspect that it doesn’t track my heart rate accurately based on my workout equipment at home. Are my steps being counted accurately? Not sure. I’ve never used the messaging or notifications on the watch. Turned that off as soon as I got it. For the money, it’s a good watch but if you’re looking for a fitness tracker, invest in something better. For perspective, I used to have a Fitbit and track all of my activity and workouts. So I went from that to this watch. Things I do like-you can personalize the watch face, the style (it doesn’t look cheap), there are a lot of features that I just don’t use like weather, music, alarm, and the watch itself is easy to navigate through all of the options.
