    1. I've been using this App for a while now and suddenly it doesn't register sleep at all. Fix this. 2. You updated the app and asked that I read The User Agreement carefully. It is in Chinese, not English. Fix this. 3. Oxygen is valuable, but only appears on watch, not in the App. Fix this. 4. BP is not 200% accurate. Fix this. 5. BPM and 02 very close.

    app verbindet nicht This app is terrible! Last update 2 days ago updated privacy policy and user agreement, it's not in English. I can't read it so I don't know what I'm agreeing to. Device won't connect via Bluetooth it says no device found, when it's been working perfectly fine for a year. When you click on lefun health app it brings up adds for Asian tiktok which I also can't read. Please fix it.... *Edit update* Device won't connect, deleted app lost a year of data. Reset device back to factory setting, fine 🙄

    uhrzeit einstellen Why won't my band stay connected to my phone? When are workout, I try to get my blood pressure and heartbeat recorded. But it's always offline. It buzzes off and on during the day. But when I need it, it's not there.

  4. tribal human-avatar

    uhr I am Do run and intense exercise atleast for 45 min........ My other tracker shows heart beat upto 145-150 but this tracker shows only 74 bpm, I do burn 300-350 calorie during workout and its shows only 70 Kcal. In such case what the use of this band and this application? Completely worth less.

  5. Jason McVetta-avatar

    test Malware. App requests 7 different permissions from Android, none of which is necessary or even useful for a smart watch. Obviously snarfs up all your messages, phone calls, pictures, and other personal data - to be sold to unknown but doubtless unsavory buyers.

    deutsch Does not respond to touch screen to search. Does not respond to touch screen DOES NOT KEEP CORRECT TIME AND. DOES NOT SYNC TO CORRECT THE TIME!!!!

  7. Zora Cooper-avatar

    google fit The watch counts I don't know what as steps. I laid it on my table next to my phone and had over 1000 steps in an hour. Not good. The app seems great.

  8. Richard Rowe-avatar

    download Just received my "smart bracelet" and installed this app. Right away I'm having problems. The biggest and most annoying is the bracelet constantly losing connection. A few times I had to take it off to keep my sanity! Maybe related to the device, or my phone, rather than the app so I can't fully blame the app. The other problem is not receiving call or SMS notifications even after enabling SMS app and granting permissions. If these were fixed I would like this app. The UI and layout is good!

  9. mandielml-avatar

    uhr koppeln Lefun has been no fun so far. I bought the kids tracker mini2. I love the functionality of the tracker itself. But utter useless in connecting bluetooth. It's driven me crazy installing app, uninstalling then reinstalling (lots how many counts). Update: I contacted the company I purchased from, even sent them a video so they could see. They are sending me a replacement. So let's see, fingers crossed the next one works.

    alternative Good app so far, needs heart rate monitor and Sp02 monitor. Edited to 2 stars, started disconnecting and requesting pairing at 1 am, on and off. Edit, I wish I did not have to give any stars, do not waste your money on Sw03 smart band, not because it is bad but because this rubbish app is the only 1 available for band, connected but will not sync, waste of time and data. Play store should allow flagging for removal due to been useless.

  11. Nancy Sotile-avatar

    I'm going to buy a regular Fit Bit or something that is compatible with Google Fit. The "smart" watch actually works fine, but this app is nearly worthless. You have to constantly tell the app to synchronize because it won't automatically do so. At least 75% of the time I tell the app to synchronize, I have to either force stop the app, reboot my phone or, on two occasions, uninstall and reinstall the app. And I've only had it 3 (three) days!!!!. I'm VERY unhappy with Lefun Health.

  12. Phil Strawn-avatar

    App initially half synched to the tracker. So it appeared to be working but only half the functionality. I force stopped the app and remaining functions activated. What i have now realised is the App does not retain daily data. So each new day you loose previous days data. Fairly pointless for a health tracker. So its visually fun and has tonnes of potential, but very probematic. Further edit. After 2 days the app refuses to see the tracker at all. Might be Bluetooth issue with the tracker

  13. Anthony Morais-avatar

    Each two days I have needed to reinstall the Lefun Health App just to restart the real clock. Always missing the real date and real time in the Smart Bracelet. This is so boring.

    No longer connects to my bracelet, everytime I try to open the app it take me to Japenese/Chinese version of tiktok, what's happened?

  15. Eugene Jason-avatar

    Both the app and wristband are faulty. Gives false data. Misscounts steps, blood pressure, heart rate and looses Bluetooth connection even when the phone is on my hand. You have to sync data manually every time you connect your phone to update data. Such a waste of 💰 😭

  16. Hayden Ng-avatar

    Worst app ever. No connection to watch most of the time. Sometimes will connect to the watch. Totally useless 😡😡😡

  17. Adam Morrice-avatar

    App doesn't connect with the device. Doesn't seem like there is any way to change the time to the correct time either.

  18. Santos Sampang-avatar

    I was updating the band and suddenly it stopped working and the band display is now black.... I can't see or do anything... please help me fix this!!

  19. Jonathan Stitt-avatar

    Update: As of this morning 5/25, the band is tracking sleep patterns again and now has a blood oxygen test on it, but no way to track it on the app. Got the update a few days ago, there doesn't seem to be any new functionality and the watch is no longer tracking sleep patterns. Also drops connection even with my phone less than a foot away. L

  20. Dave DownUnder-avatar

    At first app and watch connected straight away and everything seemed to work as claimed l was surprised but after 3hrs connection was lost and no matter how many times I install/uninstall and try everything i can think of no conection with any other devices that I have tried. Waste of $$$$$ ,I wish I had spent the money anywhere else

  21. Ashley Harden-avatar

    Just like other users my sleep is not being tracked at all and steps are way off. I restarted phone and watch and still nothing. I even have synchronized app to phone. Other stuff gets tracked but apparently I don't sleep at all. The main point of this was to track sleep. But such a bad app and cheap watch. I would honestly be fine with watch if app actually worked. I read all reviews and don't see any app creator commenting on anything. Makes me believe no ones cares about how bad the app is.

    i've seen app has new changes this is so good, but i have give you 4 stars becouse app is updating after very long time on play store(add new versions less times), i have 2 lefun watches but when i check twice, there aren't any new software versions, add new features for watches (music control, all phone notification reminder, and other good features)

  23. WEX tex-avatar

    For a €10 pedometer bracelet it does remarkably well, all connected smoothly, synchronized better than much more expensive and reputable brands (something about being fit and doing your bit). Very generous in counting steps. But three days into the process now the hour is 6 hours in advance. So slight problem. No clue how to fix

  24. harikrishna korlepara-avatar

    harikrishna korlepara


    Too generous step counter.Even without moving a step it recorded 240 steps and then compared to my phone step counter a difference of 600 steps for a mere 200 step. Not sure about other features, just first day of use. The app is to use though

  25. Aletta Mes-avatar

    It took me a full day to connect it and I still cannot find the oximeter function. I am also wearing my older smart bracelet on the other wridt for comparison, thst one has worked well for over a year but did not have the oximeter function. The readout is larger and brighter on my other watch, but time will tell. A lot of my fitbit friends have problens too. I think the oximrtrr ptoblem is a matter for the software, right?

    really struggling to connect, have re loaded app several times without success.

  27. Vishal Gopal-avatar

    Sir/ma'am please make sure that the connection of this app with band is strong, because as I was looking play store ,I saw that this app 's update was available. Then when It was finished I connected my band with this app, then I saw that the band can be upgraded then I pressed "get version info" then it showed "wait" and then my band's connection with the app was broken and I tried and tried but the band is not upgrading. I humbly request you to make changes in the app which I had told you.

    Not working correctly and clock time is incorrect. No quick start up.

  29. Prince Caspia-avatar

    Good apps & device.,but try to use findphone feature on ur smartwatch. Ur phone will sound alarm to located itself but i didnt find the way to shut it off. Just uninstalled to shut it off & install this apps back to use it...😅😅😅

  30. Yashman Zarrin-avatar

    I used mi band 3 to find app to search my phone. After using the app my phone started ringing but i couldn't stop the sound which was coming from it. I tried a lot, also off the bluetooth but it did not stop. So, at last i had to delete the app to off the sound.................. 😡

  31. Paul Henderson-avatar

    Was good but after a month I can't pair with my watch says incorrect pass key I've deleted app and reinstalled it which makes it ok for an hour but then it stops so what now as a watch that can't tell me the time is useless so it's only good for the bin 😡

  32. Khor Shau Wen-avatar

    The pacing is not accurate. I'm 6mins pacer, but the result shows only 6km after I have run for 1 hour. The distance is still like walking after I have selected Sport → Run.

  33. Scotft Lehmann-avatar

    I love the graphics of the app. But please do an up date. It keeps disconnecting bluetooth, and it's a nightmare to get started agian. Will get a 4 or 5 star if the problem gets fixed.

  34. Pete Sellar-avatar

    I have an Android 10 operating system, app is running in the background but will not open on the screen of my phone. Makes the app and the smart watch I purchased useless. Not Happy.

  35. Marg Martin-avatar

    My band keeps disconnecting and reconnecting Also a version that recorded all data like heartrate, not just when you use the phone app but from watch at all times would be good.

  36. Peter Key-avatar

    V2.02 loses all historic data i.e. tomorrow it won't know what I did today. Proved it to this version by uninstalling and going back to the previous one. Doesn't explain why the watch no longer updates the time or alarms, notifications etc.

  37. Hugo Lunar-avatar

    Could not find the smart watch it works with and most of the functions in the app did not work

  38. Josué Chávez-avatar

    The smartwatch disconnects it self randomly, and the notifications does not work, says that my phone does not support it... So much to improve.

  39. D. V.-avatar

    App is ok. It auto connects with the device via bluetooth. It sync and stores data from the watch. It automatically set the correct time and date on the watch.

    would be great if a tracker (monitor) was added for blood pressure and heart rate. like a timer. which mesdures blood pressure or heart rate every (duration like 30 minutes less or more) also add in settings all english

  41. Hamidah Hamid-avatar

    This app is always good when i wear the band. Then when i lost then found it was a bit broken but now it was fine.

  42. Bob R-avatar

    Won't sync with watch after many tries...so watch time is wrong..and none of the promised benefits of phone integration. One benefit is that spyware concerns didn't pan out. Will uninstall useless app..and return watch.

  43. Bob Porter-avatar

    Have downloaded the app but can't get it to link up with my android phone. Getting very frustrated.

  44. kobietasza-avatar

    Can not restart my daily data.. because of that i know how many steps I did over weeks.... really pore app ! But it could be good with some updates

  45. Na'Shota Lytle-avatar

    1st day all seems well. Walked over 7k steps. Next day, only the 1st few hours of me wearing the device synced. Basically before my walk. Frustrating because I need to track data for a class. Will purchase something else.

  46. Sara Mimbula-avatar

    Just got my bracelet this morning but it won't connect to the app. I have BT on and my location, but the app keeps searching and nothing happens. Is there any other way to connect your device?

  73. max rich-avatar

    What absolute garbage this app and the m4 wrist watch thing are. Tells me I've done over 400 steps, when I haven't even got out of bed. Tells me I've had over 9 hours sleep when in truth I slept from 4am to 10am. The only good thing is the heart beats per minute and the blood pressure. However, I don't even trust them, with how inaccurate everything else is. Very cheap Fitness band, doesn't keep charged, you're lucky if you get 12 hours, then have to charge it back up, 0 stars.

  74. CRAZY OPEN-avatar

    The user experience is not bad But.there is no feature for reading messages from Instagram Please bring this feature on this app on next update
