Which app shall I use for your device?

You should install our amazing app VeryFitPro

Is there a guidance on how to set the time and date on the device?

Simply pair the device with your phone, and the time will be set automatically – easy!

I love swimming, so I’d love to take this device for a swim - is it waterproof though?

Enjoy the swim then, because this device is totally waterproof! It can even withstand water immersion for up to 30 minutes at the depth of 3 meter, so you can do some diving with it in the swimming pool too!

What kind of notifications can I set-up to receive on this device?

There are plenty of functions on this device, enabling it to inform you about incoming calls, messages, reminders, physical inactivity, and even about your daily activity achievements, like for example – 10,000 steps challenge completed!

How long does the battery last?

The battery is great – it will last up to 7 days, which means that you need to charge it only on weekends!

What’s the process of charging the device?

It’s a very simple process, which only takes 2 easy steps: remove the device from its strap and plug the integrated USB connector into any powered USB port (laptop, wall charger, power bank, etc.)

How long does it take to fully charge the device?

Process is really fast - it takes only up to 1 hour!

How do I navigate the menu of the device?

For the device to start recording you don’t need to do anything – simply connect the app to the device and it will start recording and analyzing our activities automatically. To check the recorded data, this device’s touch-sensitive on-screen button allows for easy and smooth switch between the different modes.

How does this device calculate the number of calories I’ve burned?

The device first of all records the number of steps you’ve taken throughout the day and then multiplies it by the average number of calories burned by making one step! It also depends on your age, weight, height – don’t forget to fill all your data in app! Simple yet smart!

And how does this device calculate the number of steps I’ve taken?

This device uses an integrated accelerometer, which identifies every single arm movement we make and records our steps based on that. The same sensor is used by all newest smartphones, which proves it to be actually smart!

It says that there is a sport mode, but how do I activate it?

The process of activating a sport mode is super easy – simply touch and keep the on-screen button for 3 seconds, and if you want to exit it, do it exactly the same way! While the sports mode is on, it records and calculates the number of steps, travelled distance, and all the calories burned during your sport session.

I’d like to measure my heart rate, but how do I switch on this feature?

It’s very straightforward - simply tap the touch screen until a heart icon appear, and once the animation has stopped running, the heart rate measurement feature will appear on the screen – simple!

Is there a possibility that this device might have any inaccuracies in heart rate results and if yes, what might possibly cause them?

Unfortunately, it can, and it’s normal across all such devices. The key reasons for showing inaccurate results might be:
- the green light does not fully cover your skin, so the device does not get the full signal
- arm swings as well as the slight movements of the device while being worn loosely on your wrist
- don’t wrap it too tight though, as it might also cause inaccurate results! - any odd body movements, which might affect normal blood circulation, such as raising arm high and clenching your fist for example
In the end of the day, it’s still largely dependent on each person’s physiology, type of movements, location of the wear, regardless of whether you are wearing a wrist or a chest heart rate belt. The main thing to remember is – this device should not be used as an alternative to professional medical tools, and the data presented by this device should not be considered to be the most accurate indication of your health condition.

What if I don’t synchronize the device with the phone very often, will it record the data in its own memory?

Of course, it will, but only for a few days, so we highly recommend to manually synchronize the device with your phone at least once a week in order to avoid any loss of data.

I’ve noticed that the device is counting steps even though I am not even walking – is it something wrong with the device?

Please don’t panic, the device is totally fine! As it has been mentioned previously, the device uses accelerometer, which is triggered by any movements of your body parts, so if you are sitting on a chair and moving your arms, cycling, or travelling by car, it might still record these movements as steps. Don’t worry though, these small oversights have little influence on your daily activity results!

When the device’s battery dies, it switches off and automatically disconnects from my phone. Once I charge it back up again, do I have to go through the pairing process again?

First of all, we would highly recommend not to let your device’s battery fully die out, but if it actually happened, then simply charge your device back up, go to the app, and synchronize the device with your phone manually again.

I’ve noticed that the device records steps while I am driving the car – is it something wrong with the device?

Of course, it’s not! As it has been mentioned before, the device uses a sensor called accelerometer, which identifies your body movements and counts them as steps. While you are driving, you still move your arms to steer the wheel, and your body slightly moves too, depending on your vehicle suspension’s stiffness, which is why the device starts counting the steps. Don’t worry though, these small oversights have little influence on your daily activity results!

I’ve also noticed that the device counts steps while I am sleeping – how does that work?

Well, the answer is pretty much the same as to the previous question – while you are sleeping, you are probably turning around and tossing, which triggers the accelerometer and it starts counting these movements as steps. Don’t worry though, these small oversights have little influence on your daily activity results!

Why do different manufacturers' devices show similar numbers of steps but different distances travelled?

The answer is quite straight-forward – these devices are programmed to calculate steps and distances using a unique algorithm, and each manufacturer has its own unique algorithm developed, which is why the results tend to be different – it’s that simple!
