Lefun Health for PC

The device works great and can be used as a fitness starter band. It's a great device, but I am considering upgrading to the galaxy watch. The Galaxy Watch has many more features and is better at tracking your health. You can also access more detailed information about your health, including weight loss, exercise and reports. It's an excellent fitness start/beginner band. Anyone who is interested in a more healthy and fit lifestyle would benefit from it.

It doesn't merit any stars. I just got mine and am excited. My Fitbit has never been a problem, but I wanted to upgrade so that it could track my heartbeat and do other functions. It won't even set the time properly, so it is useless. It keeps saying it can't locate the device

It worked great for the first few days. My watch will not be connected to my smartphone by the app. However, the smartband's Bluetooth is recognized + paired with my mobile phone without any problems. Although I tried several times to remove the app, restart my phone and then install the app again, I am still unable to link the two devices. I can't get the app to sync up with my band. Both the phone and band show Bluetooth on, but there is no shared data. The sleep tracking has stopped working. Can't get HR & BP in app. It will tell you that you should try again when you attempt to complete something, regardless of how many times you wait. I'd give negative or zero stars.

Ok, now it's frustrating. The app works with a wristwatch that measures pulse, blood oxygen, and blood pressure. Only the app can control the watch. The app is the only way to control the watch. The watch becomes useless when there are too many ads on it. The adds won. I tried several times to uninstall and re-install the app.

Pros: Distance is measured in feet instead of miles. Although the unit system is set to IN LBS it still displays ft. The Watch Display does not turn on when I raise my wrist to verify the time. There is no workout session data - dist, cals and time, but only daily stats. Keep the stats and not erase them when there is a change. It is a shame to lose your day's data. The pros: It is easy to switch from Military Time (12-HR) time. Colorful app layout. I have not yet compared the heart rate and BP. If they pass, I will update.

The band becomes useless. App doesn't sync all data. The sleep tracking has stopped working. Cannot access HR & BP via app. 12/31: A new watch face was unveiled overnight. It looks great. It's great to have intermittent connectivity and sync. Manual sync fails often, as does HR and BP. 12/29: It worked great up to the last update. It won't sync data with band now. Band is already connected. Bluetooth connectivity is visible on the band. I tried all the troubleshooting suggestions from the Help section but to no avail.

The app doesn't sync R8 and BP. Multiple attempts to record manually. The number of goals set is too low. It is difficult to shut off. To run background 24 hours a day, leave icon in the notification bar. Why? Why? The M3 Intelligen Health Bracelet is my favorite. Beware! Be careful! It will still work if you put it back together. Micro USBs are longer than other types of devices. It comes with the correct cord.

Okay, I am glad that I don't have to experience this problem alone. But it is not my fault. When I open the app, an advertisement appears each time the app closes. It is impossible to get in. After a while, it stops working. The ads start and then the app shuts down. Already uninstalled, I reinstalled the app once. I don't want to do it everytime. If it weren't for the ridiculously useless and ineffective app, then my watch works perfectly. This problem must be fixed.

The wristband was okay, and it was effective. But this app is horrible. It is difficult to use the app, and it crashes frequently. There is no way for me to convert temperature units from Celsius to Fahrenheit. If you are able to read Chinese, there's no online help.

It works for most of the time. The F3 watch I purchased from eBay was advertised with Android devices. It could control and manage your Android device's mp3 player, handle calls, etc. Although the app displays your phone's status and a SMS reminder option, it does not display music controls. Unfortunately, the text-to-phone notification function hasn't been implemented yet. Referring to the above, I have an Android at&t phone called a TETRA and am running the most recent Android version. It does detect the camera shake to click and syncs steps, blood pressure, heart beat, etc. The app says my heart rate is incorrect, but it doesn't know what to do. It's a random algorithm, 99 percent of the time. It's not expensive. If you want precision, invest $200 in a Fitbit. My main interests are time, steps and resistance. If you are frustrated by the military time, go to Personal Setting to change the 24 hour range, and then sync again. Sometimes, your phone might need to be reset to reconnect.

Here is an updated review that I wrote in June 2019. The app was rated 2 stars at the time, as most functions were not working. After that, I tried all previous versions and got the same results. I reached out to developers but was not answered. The app is not working so you can uninstall it. You could also use the smart band to track your steps. Everybody knows that smart bands are only as useful as the apps that support them. This one doesn't do anything. .

It is not worth it. Poor product. Installed apps on the phone are a step. Calorie counting is better. It does not connect to the device. It is not accurate in displaying steps, distance, date, hour, etc. It is annoying to need to disassemble and recharge the wrist band in order to use it again.

Correct the steps, they show an extremely high number and a short distance. The sleep function does not work correctly. It shows 10 hours sleep but gives no breakdown. Apps cannot be loaded or worked on without your permission. You must delete or force stop the app before you can reload. It also takes you to an unspecified site when you search for updates. If you can fix it, the app offers many possibilities.

The app and bracelet are both disappointing. When the Bluetooth connection is lost, the bracelet will automatically reset. Displays the heart rate in beats per minute. The Sleep Mode does not detect a sleeping cycle and it is no longer available as a choice. App asks user to accept terms in Chinese. Nearly all of the functions are manual and not automatic. Settings don't stay set. You can keep going.

Watch and app are not in sync and have never been able to keep track of any activity. No sleep history or steps. Every other week, maybe once a month I will get an SMS notification from my phone. It is switching from a 12 hour to a 24 hour time system. The app is useless at the moment. It will only change the time automatically. EXTREMELY DISAPOINTED. WASTE OF MONEY
