    Before I begging let me tell you; this watch is definitely the BEST WATCH OUT THERE. We have been using this watch for over 14 days.

    Battery: battery really last a long time on a single charge. One single charge and battery is still going.

    Screen: The screen it has a large screen, bright and easily to move around. It also allows you to choose your own image as a background.

    Apps: it really tracks lots of features very accurately like sleep, steps, heart beat, it also has many nice features.

    Phone app: it’s very simple to look at your data and understand it. Phone synchronization it’s very easy to do.

    Did I mention waterproof.

    Out of the box: watch, instructions manual, charging cable. You will need a 2ah square charger (not included)

    This is a nice fitness tracker and so much cheaper than an Apple Watch!

    It has a lot of good functionality like step counter and heart rate tracker.

    I like that the screen is big and colors stand out well. It’s very vibrant

    I just got this and set it up. I’m not a tech person AT ALL and this was very easy to set up. The instructions were laid out very well with lots of cool tips and features to opt to use. I have an Android phone and used Google play to set up the app. I especially love the period tracker but I mainly bought it for the step counter and reminders to walk and drink water.

Please login to post questions.


How to set a time and date?



The date and time of the tracker will automatically synchronize with your phone after your watch is successfully paired with your phone in the App.


How to connect to a smartphone?



1)Search and download the APP Fitcloudpro from Apple store or Google play or scan the QR code in the user manual. 2)step 1: Enable Bluetooth on your mobile phone. Step 2: Launch Fitcloudpro on your mobile phone and register an account. Step 3: Follow the in-app instructions to create your profile. Step 4: Tap Mine> Device> Search on your mobile phone, then tap the model name to connect.


How to charge the smartwatch?



Insert the USB end of the charging cable into a USB adapter, power bank, or a USB port. Hold the other end of the charging cable to approach the charging pins on the back of the watch until they attach magnetically. Note: If the charging cable can not magnetically attach on the charging pins of the watch, please change the direction of it.


Can I set the watch display time?



We can't set up the display time. But you can enable "raise to wake" in the app, then the display will light up when you up to your arm.


Does the data not accuate?



1)If the watch data is not accurate, Wearing the watch so it’s secure, but not too tight, and wearing the watch higher on your wrist (about 2-3 finger widths above your wrist bone). It is better to fill-in personal info including height, age, tall, etc in the App Fitcloudpro. 2)If the data on the APP is not accurate, please keep the APP connected to the watch, and you can try to swipe down on the dashboard of App to get fully synced. Then all of your data will be synced to the app manually. 3)If the step data is not accurate, we would like to give you some tips. The devices use a 3-axis accelerometer to understand your motions. The device has a finely tuned algorithm for step counting. The algorithm is designed to look for intensity and motion patterns that are most indicative of people walking and running. When working at a desk, cooking, or doing other arm movements, a device on your wrist can pick up some extra steps if it thinks you're walking. Many of these situations—such as working or cooking—do include a few steps in-between stationary periods so the device tries to give you credit for those steps. For the vast majority of customers, the amount of stray steps accumulated is negligible when compared to the entire day. 4)If the BP data is not accurate, user wears the watch and keep it close to skin, then green light flash, press and hold touch button and wait 8-10 seconds, results comes on. For blood pressure testing, may need to wait up to 8-10 seconds. Besides there are some tips need to pay attention: Keep body relaxed and still while testing. Keep device at the same height as where the heart is, and don’t talk while you are testing.The watch will automatically test blood pressure. After syncing, the results captured will be presented at the blood pressure interface in the app.


Why the watch can not receive messages?



Please confirm if the watch is connected with the App FitCloudPro. If yes, go to check if the SMS is turned on in the App. The watch only works and reminds after the SMS notification has turned on in the App. Then go to the settings of Mobile phone>Notifications>Find the Messages>Allow Notifications.
