The first GPS bracelet — NO.1 F5, anything new about it

Recently NO.1 smartwatch releases a new model, the bracelet series NO.1 F5 Buy from here:

As a fitness band, F5 is built for sports. It has built-in GPS sensor, independently, you can use the GPS without your phone. NO.1 takes advantages of the GPS in the sports. Cycling, climbing, running, it will record your trajectory, speed, time, distance and of course, the calorie burnt. Check the pics below, my colleague went to cycling weeks ago with the F5. This is the trajectory the F5 recorded, you can check this on the companion app. In the left window, click the map, you’ll get the full trajectory, like the right one.


As for climbing, this bracelet is more professional. The built in GPS sensor can record your route, the altimeter can real time display the height, you can see the increasing altitude with your legs moving. Beside, the real time changing Air-pressure, this is also very important when you climbing the mountains, it is important for your health.

Last but not least, the thermometer. F5 has built-in thermometer, not like the previous products, which receive the data from internet, it can real time display the temperature, just like the Casio watch, with a fire nearby, the result will increase rapidly. You don’t need to worry about the wrong positioning, wrong data/temperature like the previous products. Real time temperature measurement will give you the a correct result.1_副本


As a fitness band, F5 supports Heart rate measurement, calorie burnt, steps record; besides, the app can record the sports data, as you can see the left one is the sleep quality, below is the heart rate; and the right one is the calorie burnt. It will help you achieve fitness goals.

With good hardware and companion app, what users need is a durable frame, a waterproof structure. The frame is not metallic, as we know, metallic frame will influence the GPS signal, so we use some light but durable material to build up this tightly, waterproof structure, so you can have a better user experience.

Any question please feel free to comment, I’ll reply as soon as possible.

    I used an F5 smartwatch for 1 month. The altitude meter shows below zero from the 2nd week but I live ~240 m above see level. The air pressure measuring is correct. How can I solve the altitude measuring error?

    Thank you very much,

    It’s a good idea to do:
    First, open the firmware source code: I need to fix some bugs and improve some features, especially gps and sports activities. when you open the source code, another user can help.
    second, open the bluetooth communication protocol: HPlus is not so good either.
    and both have infrequent updates.

    My no. 1 f5 smartwatch restarts automatically almost every day. This is happening after update manually from 1.63 to 1.66.15. Now when it’s restarts the whole activity resets to zero no back up, so everything is lost. Kindly advise me for the same. Also i have a minor scratch on glass so how to replace it. I think it is a screen protector.

    I got the F5 with firmware 1.58.7, I tried the app (HPlus 3.3.7) to update and it keeps telling me it is up to date. Now I have tried to upgrade manually to 1.66 and the following keeps happing: uploading (starting DFU-starting bootloader=disconnected-connecting-starting DFU-disconnecting)-upload failed, at the bottom of my screen the following message appears ( GATT INVALID HANDLE) and the watch resets.

    I have bought DTNO.1 F5 watch. Now I have it for a week. Batery is verry good. i have not turn off the watch yet, and it works. Baterry has not drained even a half and I use GPS and sport programs every day. I have a proposal to tell your engeneers to make this watch better together with HPlus software for phone.
    It could be very helpful to for me as a sportsman (I am a runner) to see seconds on watch, and on HPlus aplication, especialy in “Activity”. I can only see minutes how long I have run, but not seconds. Also stopwatch and counter (programabile) are missing in this watch. I belive that sportswatch must have this two things. One thing what is missing is possibility to store results on computer or in cloud.
    After running I have tried to share my run on public network with map, but I did not succedit. Only lane without map is wisible on picture, although in HPlus aplication I can see everything.
    In sportsprogram it could be good to put Gym and Fitness. Now I use in Gym program for Trademill but it is not that what I need.
    Sometimes, when I work in the night, I sleep during the day. Why I can not setup time for sleep monitor?
    Also it could be good to se batery in procent. Maybe only in HPlus aplication?
    Can I buy anywhere protective film or tempered glass to protect display for this watch?
    But I must say this is a great watch for this money. Other than That, great battery life. I hope I will use it for long time.

    I bought the watch in February 2018. In the same month I manually updated the firmware from version 1.58.6 to 1.60.5. Yesterday I wanted to update from 1.60.5 to 1.63.0.
    During the installation but (about 7%) the update failed.
    The display is off and the watch just buzzes and vibrates until the battery went out (it took about 5 hours). Buttons do not respond. I wanted to charge the battery again. When I connected the watch to the charger, it starts buzzing and vibrating again.
    After a poor update, the watch is down. What can I do with it?

      Hello there, sometimes it happened but don’t worry, you just need to use the firmware/app to connect the dead watch and then update the firmware. (Make sure your phone screen is lit) After the installation goes to 100%, the watch will be alive again.

    Too bad – could be good but the fact that all your data is not synced to an account means it can all disappear if you use a different phone or ever replace the F5. The app needs serious work, as does the firmware on the watch. For example, we need the ability to delete gps workouts.

    After two months of use in running, completely unfinished, like many Chinese products, simplistic Hplus application.

        Hi Jon, I am running this firmware, and it is good that the GPS is improved, but some more improvements are needed still. The tracking of activities is very limited (not what we see during the activity, but what we get in Hplus), and we need some kind of export (at least GPX, if possible TCX). The addition of “Find your way back” will also give a better usage of the GPS.
        I still like the watch, but replaced it by a Suunto. It’s not working well enough to replace a proper sport watch (even if I actually find it less buggy than Garmin :). Returned the Garmin, kept the F5)

    I’ve bought F5 on Gearbest they have told me that I can turn off bluetooth on them, but it’s not possible. I don’t use F5 with my smartphone since it’s not really necessary, I would love to see option to turn the bluetooth off and not radiate BT all day long without any reason. Could you please add option for disabling BT? It’s the only thing I don’t really like on my F5 and screen brightness is not working no matter if I set 1,2 or 3 it’s always the same 🙁 and also the display isn’t very straight placed it’s a bit askew, but it’s fine.
    I’ve also installed the firmware from guide you have posted and it’s much better, the new GPS interface is awesome. Is the Hplus app working for updates? I had 1.58 version and it was showing I that have the latest firmware, but in the guide there was 1.60… so OTA updates don’t work?

        I have latest Hplus, but it always says latest firmware, but even it’s not true.
        Also the brigthness function will you fix it? It’s not working for me at all no matter if I set 1,2 or 3 it’s still same brightness. Completly not visible on sunlight…
        Thank you.

          Hello Mattthev, I’m sorry, I don’t know if it is possible to add the option to turn off bluetooth. There will be a new firmware, it improves the GPS positioning interface. About the brightness, I’m afraid we can’t improve it, it is the hardware, the limitation of this kind of screen.

    I tried to record some of the activities, I tried the basketball one, saved it but I can’t see it in the phone app. Looks like the app only shows 4 activities (walking, running, hiking, biking), there’s no way to measure swimming on the watch, but on the app it shows as an option in the “Goal” section. On the watch, there’s option to record treadmill, basketball, badminton and soccer, but does not show on the app. Please let me know when the next update will be and if it will address these issues. Thanks!

    Hello. I’ve jus bought F6 and:
    1. Why there is no stopwatch? It is simple programming thing for this watch. And You can make tapscreen with this hardware platform You have like timex for example
    2. Why there is no timer? It is good for sport, for some exercise, good for sport rutines, good for interval training
    3. Why there is only one alarm? In proggrams You can do anything;)

    I have a problem with time format (there is only 12h possibility). F5 actual FW is 1.58.6. I have used your offered SW to upgrade FW to 1.60.5, but w/o any success. The final message was “upload failed: GATT INVALID HANDLE”. I have tried and APP HPlus (version 3.1.7) there is info that “latest version already”. Why I can´t upgrade the FW ?

    The firmware upgrade page leaves out steps and it wont work for me. Do you install the firmware APK through the DRU app by selecting “Application” as the type? I tried all options but the DRU app states the firmware APK is an “invalid file”. The upload button is never available. Please assist.

      I figured it out. You need to explain that the firmware is incorporated within the standalone app, in the linked APK. I installed the DRU app first and was trying to load the linked APK as the watches firmware – confusing documentation.

    Hi, I use F5 with on IOS 11.2.2 and HPLUS
    I think that the hardware could be good but the firmare must be very improved
    I find the following problems:
    •The recording of sleep goes on alternate days sometimes I find it, other times not, with the smartwatch always on my wrist
    •There is no export of the gps track towards Strava or other systems.
    •The recorded track does not show the map in Italy
    •You can not configure the altitude, on the smartwatch there is a reset but only at sea level and I instead live in mountain. Is it necessary configure the altitudine before each trekking but I can’t go to sea in order to reset.
    • Whatsapp messagese aren’t shown, you see only the sender

    I hope that my indications can be useful for the next release of the app and/or firmware

    • Jon

      4月 th, 2018 3:17 下午 Reply Hello Matteo, thanks for your report, about the map, please try our latest firmware. It is a pity that F5 can’t export the GPX file and the altimeter, it is a Relative height measuring. Yes, the whatsapp doesn’t show in the F5, it is the problem of the Hplus, you can try the HPlus Watch app. I heard that whatsapp notifications work well with it.

    Buongiorno ho installato manualmente l’ultimo aggiornamento del mio F5 v1.60.5 e ho notato un problemino. quando vado sull’orologio ad impostare la data e seleziono il mese il display inizia a lampeggiare in modo anomalo. Inoltre darei un suggerimento per il prossimo firmware, l’accensione del display con il movimento del polso attualmente ad ogni movimento il display si accende e si spegne questo procedimento non è molto funsionale quando si fa sport perche avvolte basta un movimento per far si che il display si spenga. io suggerirei che una volta acceso il display per il movimento del polso si debba attendere il tempo impostato per lo spegnimento, e non che a ogni movimento il display riceva un imput di accensione o spegnimento.

      The altimeter is a Relative height measuring. Not the same as the barometer measuring the Air-pressure.
      Although F5 is IP67 waterproof, we are not recommended to take it for swimming, because the barometer sensor, we could not create a highly sealed frame for it.

    Hello there. I just received my NO. 1 F5 and I have a problem with my notifications in android .. I can see notifications from almost every aplication except from whatsapp. I cannot see any coming to my phone… Any suggestion? It is a bit confusing. Thanks

    One more issue I have found is that it is almost impossible…. (Almost is very optimistic) to see the screen outdoors….. Today it’s not a sunny day and I cannot see anything outside…. Any expected firmware to. Solve this issue? Otherwise is useless outdoors. Thanks

    One more issue…. The gps {after more than 30 minutes test outdoors} does not recognize my position at all. It says I am in Africa while I am in America…. Also the GPS time is 17:40 while my actual time is 12:40. Any idea how to setup properly the gps? Thanks
