Fitness Tracker for Men and Women,Fitness Watch Waterproof with Activity Tracker and Sleep Monitor,Smart Watch for Android and iOS Phones

Shows time, date, steps on the main page. Other pages give more personal information- heart rate, blood oxygen, skin temperature, etc.It holds charge about 3 or 4 days. You can charge it over night by plugging the face of the watch in at night when you notice the battery going down. Good buy!

I don't write many reviews, but I am so unhappy with this tracker that I wanted to warn others. The only redeeming quality it has is that it does keep track of the date and day of the week. Other than that, nothing else works correctly. These are the following problems I have had with it:1. Doesn't remotely count steps correctly.2. Loses time and has to be charged frequently.3. Whatever material is on the face of the watch is so inferior it gets marred easily. I can wake up after a night's sleep and find marks on it.4. It frequently changes the settings on it and it is not intuitive on how to change them back.5. The mobile app leaves a lot to be desired.6. It is so inaccurate, it can tell me my blood pressure numbers without the watch even being on my wrist.7. It's supposed to give you the time by lifting your wrist, but frequently that doesn't work and you end up having to scroll through all the options just to get the time. That is my #1 pet peeve! It is VERY frustrating.Bottom line, don't waste your money. I should have sent it back at the beginning, but now it's too late. It's just trash!

Nice fitness watch, love the color and narrow band. Works well

For the price I'm pleased. You do have to sync it manually everyday. I just wait till the end of the day. The information that goes over to Google fit doesn't match but that could be a Google issue so I don't worry about it. I just broke the one I have so I hope this next one works as well as this one has.

I bought this watch because I wanted to explore a fitness watch at a low entry point until I can decide if I want a more capable and more expensive watch. This particular watch requires the use of the Runmefit app to get the most out of it. This includes more complex activities such as recording and displaying sleep data during the night, but also simpler tasks such as setting the watch to display temperature in Fahrenheit and to select the watch face appearance, so the app both receives and transmits to the watch.I had a lot of problems with the app I downloaded for my Android phone. It (not me!) disconnected Runmefit from bluetooth and when I tried to reconnect to bluetooth I kept getting the message that it needed app location permissions turned on … which they were! It at least showed that it still recognized the watch as a “device.” Until I tried to remove it as a device and then reconnect it, thinking maybe that was necessary to get around the bluetooth problem. When I tried that, the app wouldn’t recognize the watch (“device”) at all.So I downloaded Runmefit to my iPad, to see if it would run better there. It immediately connected with no issues. Thank you "Walled Garden"!One other thing to know that you don’t find out until you stumble across the S5 Operation Manual several layers deep into the app, is that the way to move through the various functions on the watch is to tap the little rectangle on the bottom of the face. Also, when the Android app no longer recognized the device (let alone establish bluetooth connection) it would no longer show me the Operation Manual, probably needing to know what kind of device to know what kind of manual … I guess. That makes sense if the app is written for more than one kind of device. Probably works the same on my iPad, but you can bet I’m not going to remove the device from the app just to find out.I have no measurement comparison (other than my thermometer for temperature) for some of the various medical data (heart rate, blood pressure, blood oxygen) but I’m hoping to collect that data on my next doctor visit for comparison. The documentation says that data is “for reference only and cannot be used on a medical basis” which I interpret to mean there are no guarantees or even tolerances (e.g., +/- 20%) for those results. Maybe those are in a specification sheet … somewhere. But that’s okay, as long as the results are reasonably consistent I can record my numbers on a daily or weekly basis or whenever I think of it, and compare the results myself to see if anything is changing in a sinister fashion.The Sleep measurement shows that I slept 8 hours 40 minutes last night. My cpap machine says I slept 8 hours and 45 minutes. That’s amazing, the watch is getting that (and the heart info) from sensors on the back of the watch. The watch shows me the instantaneous values of things like blood pressure and then the app can display a graph showing how they changed during the month. I’m guessing my blood pressure spiked when I was trying to get the Android app to work.I’m not reporting on the various exercise functions, I haven’t tried them out. The watch does tell me how many steps I’ve taken and how many calories I’ve burned during the day with no setup required from me.And maybe the Android app is just fine, maybe I just bungled the initial setup and couldn’t dig my way out, silly me :-( . I’m reporting my misadventures to help out anyone with similar difficulties.*** edited 5-13-23 *** I visited my dentist and after the hygienist measured my heart rate and my blood pressure I compared the measurements she took with those of the watch. Very nearly identical. However, blood pressure measurements seem particularly iffy. Just now I took six consecutive measurements and measured 111/73, 121/83, 126/80, 114/64, 114/64, 108/70.*** edited 6-13-23 *** First watch I've ever owned that I can't read outside in the daylight. Frequently the app will disconnect from Bluetooth, and it is a simple matter to reconnect it in 'Devices.' The clue is that you can't read any chart data on the app because it can't connect to the watch without Bluetooth. And the app won't show the display face options if it is not connected to Bluetooth.*** edited 11-2-23 *** Some temperature data I collected when I wasn’t feeling well, a bigger variation than I was hoping for.Oral thermometer: 99.6Infra-red forehead: 98.6Watch: 97.8Consecutive morning battery voltage levels (as reported by the watch) from a full charge: 100%, 97, 78, 54, 45, 34 and then it quit later that day; so I got almost 5 1/2 days on a charge.*** edited 2-2-24 ***. The watch strap broke! The strap comes in two pieces, one attaches to the top of the face and one attaches to the bottom of the face. The bottom strap is the one you remove to recharge the face piece. The top strap has the buckle and is the one I never remove. Until now.This might be my fault if I was grabbing onto the top strap as leverage when I removed the bottom strap for charging. If I was doing that, I might have broken the glue bond to the top strap. In the future I will be sure and only hold the watch face and not the top strap when I am trying to attach or remove the bottom strap. I glued the top strap back to the top of the watch face with a super glue. It seems to be holding fine.*** edited 8-4-24 *** . My watch would no longer link to the app. I switched to a new, unused watch that I bought recently and it connected fine. I had to update the app and also the watch firmware.*** edited 8-31-24 *** I’m getting shorter charge duration with the new watch. From a full charge: 100%, 78, 48, 21 and then it quite early in the last day. I got just over 3 days of use on the charge.*** edited 12-9-24 *** Select the watch display and the 'How to use' options such as 'Device connection' and 'S5 User Manual' work again. Yay!

This is a great product for the price!! I accidentally broke my first one after two years and re-ordered the very same thing. This device gathers as much information as those on the market that cost much much more.Please contact customer service if you have any problem setting this up. I did have a little trouble getting it set up, but customer service worked with me until it was figured out. This is what I finally did and now everything is working as it should. I removed the app from my phone, deleted my device from Bluetooth, and started over. This linked all the information between Bluetooth, the Runmefit app, and my device. I couldn’t be happier. 😉
