Before you start using your Letsfit ID115U Fitness Tracker you will need to charge your device for 10 minutes. To do this pull apart the watch strap from the middle section, the USB is under the touch key button.

You will then need to download the app that works with the Letsfit ID115U, the app is called VeryFitPro and is available from the app store for iOS user and the Google Play Store for Android users.


The Letsfit ID115U has some system requirements of iOS 7.1 and above or Android 4.4 and above.

After 10 minutes you can remove the fitness tracker from the charger.

You will need to ensure you have enabled Bluetooth devices on your smartphone, this will be under your settings section and look for Bluetooth and ensure that it has been enabled.

Search for “ID1115U” and pair the fitness tracker to your device.

Next open the app on your phone and set up an account, you can input details without creating an account, but if you later set up an account it wipes the previous inputted data. So, it’s best to create an account to start off with.

    I can’t seem to get the sleep mode set up… so I can’t monitor sleep… not sure if I’m doing something wrong? .


      (2nd February 2018 - 9:09 am)

      Hi Patricia,

      Thank you for your comment. Have you created an account on the VeryFit Pro App? Also have you tried to refresh the app when you open it up? I have found sometimes the data has not been synchronized across automatically and needs a manual refresh in the app, to do this press and hold and in a scrolling down motion the page will start to synchronize, you should see the sleep data appear if successful. Hope this helps you, if not feel free to come back to me and i will see what i can do to help.



      (5th April 2020 - 5:04 pm)

      I received my Letscom Fitness Tracker from Amazon yesterday and the day and time are wrong. I have unbind the device, turnoff the Blu tooth, and all steps that I found on YouTube, lol. But seriously, I still get it to change. Please help, Iike it so far. It’s just the date and time thing is getting annoying


        (6th April 2020 - 12:22 pm)

        Hi Tasha,

        The tracker uses the exact time of your device. In order to correctly display the time you need to bind it to your device. Every few days you’ll need to refresh the app whilst to transfer data and maintain an accurate time.



    (15th March 2018 - 7:29 pm)

    Bought this as it said “waterproof” as I swim a lot. Disappointed that now it’s arrived, it’s only waterproofed enough to wash your face or to wear in the rain.


      (19th March 2018 - 1:31 pm)

      Hi Marie,

      Yes, you’re right, they do list it as Waterproof on Amazon, I wrote my review and listed it as Splash-proof as the IP67 rating only allows you to immerse the product in water at around 1M for only 30 Minutes.
      Have you tried to contact Letsfit? they might be able to help and even accept a return.
      Hope this helps.


    (19th March 2018 - 3:19 pm)

    Does it automatically record your steps and distance or do you actually have to manually put it on that setting?
    I don’t want to change settings for basic steps.


      (20th March 2018 - 1:17 pm)

      Hi Sonia,

      The Letsfit ID115U automatically collects data for steps, calories burned, and distance travelled. This data is transferred to the VeryFitPro App for you to see.

      Hope this helps



    (20th March 2018 - 5:21 pm)

    Transferred via Bluetooth?


      (21st March 2018 - 9:47 am)

      Hi Sonia,

      Yes, all data is transferred via a Bluetooth connection.


    (25th March 2018 - 3:42 pm)

    How do i change the time now the clocks have gone forwards?


      (27th March 2018 - 9:47 am)

      Hi Helen,

      Thank you for your comment. The time should be updated automatically as the fitness band is synchronised up with your smartphone.


        (27th March 2018 - 12:27 pm)

        Hi darren

        I expected this to happen but it hasn’t. the phone time is correct and the tracker has synched with the app to download steps but the time has not changed.


          (27th March 2018 - 12:42 pm)

          Hi Helen,

          Can I ask what device are you using? Have you tried the following method Open VeryFitPro App > User Icon (On Bottom Bar) > Synchronize Now.

          You can always reboot the device too; your data should be saved onto the App and the device will reset itself. To do this follow this method Open VeryFitPro App > Device Icon (On Bottom Bar) > More > Reboot the Device > Confirm



    (9th April 2018 - 9:49 pm)

    The tracker is sayingvthat today I have done 25,345 steps and although I have done a 3mile walk I definitely haven’t done 25,000+ steps. Why is it tracking way more than Iv done?


      (10th April 2018 - 9:22 am)

      Hi Lucy,

      Could you’ve have been swinging your arm more that day? The tracker works of motion from the arm to detect a footstep so sometime depending on the activity of that day the step count can rise.


    (21st April 2018 - 4:44 pm)

    My calorie tracker says I burn about 197kcal daily and I’m not sure if that means just 197 calories daily or 197000 calories daily but either way it seems really off? Not sure what to do about it? Any ideas?


      (26th April 2018 - 1:42 pm)

      Hi Mike,

      It will mean 197 calories based on exercise motions only!


        (26th April 2018 - 6:23 pm)

        Hey Darren,
        Thanks for the reply, It’s definitely still way off. Unless “exercise movements” means flailing your arms chaotically. I run and have a daily 1 hr routine workout but I only burn 197 calories? Not likely.

    How often do you need to sync the device to your smartphone? My daughter has been wearing the device for a week, but when I synced it today, it only gave me the information for today. Do you need to sync it daily?



      (26th April 2018 - 1:45 pm)

      Hi Lawrence,
      Have you tried to contact Letsfit? They might be able to assist with your syncing issues.


    (22nd May 2018 - 4:05 am)

    Am I able to see the number of steps and calories via the display on the tracker or only on the App?


      (11th June 2018 - 12:01 pm)

      Hi Janet,

      You can see the information on both!


    Jeff Albaugh

    (30th May 2018 - 11:26 pm)

    It works fine but the time is t correct, is there a way to set the time?


      (11th June 2018 - 12:01 pm)

      Hi Jeff,

      You’ll need to refresh the tracker via the App, then the time will be correct.

    Just back from holiday abroad and the app won’t stay open for any length of time to sync or reboot


      (20th June 2018 - 9:58 am)

      Hi Shirley,

      Please contact Letsfit via email, the address is support@iletsfit.com

      I would like to change the intensity if the lighting while I’m outside so I may see the screen better, is it possible and If so how? ( I have an 115 plus HR)


        (28th February 2020 - 10:49 am)


        I’m afraid not.



    (12th July 2018 - 7:47 pm)

    I got this watch yesterday. It came with a purple band. I got the hang of this watch except for one thing the heart rate it won’t work for me and I don’t know why.


      (17th July 2018 - 10:55 am)

      Hi Mallory,

      The Letsfit ID115U does not come with Heart Rate functions.


    Vicki L Anderson

    (18th July 2018 - 2:07 am)

    My watch will not turn on. When plugged in I have no light


      (19th July 2018 - 11:03 am)

      Hi Vicki,

    Can you change the home screen on the watch?


      (1st April 2019 - 1:35 pm)

      Have you tried to press and hold the multi-function button when on the homescreen?


      (9th September 2019 - 1:44 pm)

      How do i reset my steps for the day so it starts at 0? I woke up this morning with step count from yesterday.


    (13th April 2019 - 10:19 am)

    Do you have to set your step size? If not – what does it estimate your stride is?


      (15th April 2019 - 12:28 pm)

      Hi Anya,

      The step count is done automatically and uses the swinging motion of your arm to calculate each step, hope this helps.



        (16th April 2019 - 8:02 am)

        Hi, Can I maually put in steps done like when i worked out?


          (16th April 2019 - 1:00 pm)

          Hi Sariza,

          You need to be wearing the tracker in order to track your movements, there is no way to manually record this.



    (30th April 2019 - 8:34 am)

    I have the ID115U. tracker is counting approximately an average of 345kCal burnt from waking to sleeping, errmm I burn on average in excess of 2000kCal per day. What is the reason for this reading being incorrect, all is set up properly. Does this tracker not count all calories burned?? It clearly claims that it counts Daily calories burned OR at the very least it does not clearly state that it doesn’t?? ………….. Daily Health Snapshot Check your daily steps, calories burned, active minutes, and miles covered to get a general idea of your progress towards your goal. ???


      (30th April 2019 - 12:48 pm)

      Hi Ash,

      I don’t have that kind of information available, I just reviewed the product and don’t know how it fully works. For that information you’ll need to contact Letsfit via email support@iletsfit.com

      Have a great day!

    How do you change the distance from kilometres to miles. I bought two fitbits at the same time and one measure distance in miles and the other in kilometres and I would prefer it in miles but cannot find how to change.


    (23rd June 2019 - 9:44 am)



    (15th July 2019 - 7:06 am)

    Hi, How do you reset the sleep settings, so it will record your sleep during daytime hours. I work at night.

    (26th July 2019 - 9:09 pm)

    I’ve followed the instructions to switch my display to go from vertical to horizontal but when I press more the display icon doesn’t show up. How would I be able to change the display?


    (9th August 2019 - 10:39 am)

    Hi I have this watch but it keeps saying I have done many more steps than i have done. Is there a way to correct this pleaseee

    Sandra crusco

    (14th January 2020 - 1:33 pm)

    Hello. I’ve just bought letsfit tracker and I would like to reset it as I have notas yet done a proper work out and it has recorded steps I have not done while sitting in my chair. Please advise.


      (20th January 2020 - 1:19 pm)

      Hi Sandra,

      The tracker ‘records’ steps by recording the swinging movement of your arm, you can however use one of the programs before your start an activity to record your progress whilst doing that activity alone.



    (14th February 2020 - 5:58 pm)

    Hi. Is there a way to turn off the flashing green light on the back? At night it’s quite annoying. Flashes both if I’m charging or not charging it. Thank you.


      (28th February 2020 - 10:39 am)


      That light cannot be switched off, it’s what is used to monitor your movement.



    (3rd August 2020 - 7:43 am)

    This is a really useful page – thank you. I have a Letsfit ID115U and on several occasions have accidentally started the timer / stop watch feature but cannot work out how? or what I do to stop it? Do you know how to start or stop timer function?


      (3rd August 2020 - 1:10 pm)

      Hi Caroline,

      Yeah, that happens sometimes. To stop and reset the timer you’ll need to scroll through the menu until you locate this programme, then press to stop and press and hold to reset.



    (3rd August 2020 - 2:49 pm)

    Thank you for such a prompt reply – do you know how I can deliberately start the timer, so that I can then test whether I can stop it?


      (13th August 2020 - 12:58 pm)

      Hi Caroline,

      You need to scroll through the menu until you see the timer, press and hold the multi-function button to start the timer, and press and hold it agian to stop it.
