Your Smartwatch Setup Guide: A Walkthrough for the G53, Apps, and Notifications
Update on Oct. 31, 2025, 6:35 p.m.
So, you’ve just unboxed your shiny new smartwatch, and it looks fantastic. But let’s be honest, the tiny, folded paper manual it came with is… less than helpful. You’re probably wondering how to get it connected, why your notifications aren’t showing up, or how to find the right app.
Don’t worry. This is the part that trips most people up, and it’s completely solvable.
Think of me as your patient guide. We’re going to ignore the marketing jargon and just focus on getting you set up, step-by-step. We’ll use the RUXINGX G53 Smartwatch as our main example, but these steps will work for almost any modern, app-connected smartwatch.
Let’s get this working.
Part 1: The “Golden Rule” of Smartwatch Apps
Here’s the most important secret: The app is the true ‘brain’ of your watch. The watch itself is mostly a screen and a set of sensors. The app on your phone does all the heavy lifting—the calculations, the data storage, and the settings.
This is where 90% of setup problems happen.
Users often go to the App Store or Play Store and search for their watch’s brand, like “RUXINGX.” Sometimes this works, but often (especially with flexible-brand watches) you’ll find nothing, or a dozen confusingly-named apps.
This is the solution:
- Do Not Guess: The only app that will work is the one the watch is designed for.
- Find the QR Code: Turn your watch on. Before it’s paired, it will almost always show a QR code. If not, check the back of that tiny paper manual.
- Scan the Code: Open your phone’s camera and scan that code. It will give you a direct, non-negotiable link to the exact app you need to download. For many watches, this might be a popular hub app like “Da Fit,” “VeryFitPro,” or “GloryFit.”
Searching for the “ruxingx smartwatch app that works” is frustrating because the app probably isn’t named “RUXINGX.” It’s the app the QR code points you to. Trust the code. Once you’ve downloaded that specific app, you’ve completed the most difficult step.
Part 2: The Two-Part Bluetooth Handshake
Okay, you have the app. Now, let’s get connected. Most users think there’s one Bluetooth connection, but for watches that handle calls, there are two. This is critical.
Think of it as one handshake for data and one for audio.

Connection 1: The App (For Data)
- DO: Open the app you just downloaded.
- DO: Go to the “Device” or “Add Watch” section inside the app.
- DO: Let the app scan for your watch. When it finds the “G53” (or your model), tap to connect.
This first connection syncs your steps, heart rate, and notifications. It’s the “data” handshake.
- DON’T: Do not go to your phone’s main Bluetooth settings and try to pair it there first. The app must initiate this first connection.
Connection 2: The Phone (For Calls & Audio)
If your watch, like the RUXINGX G53, can make and answer calls, it needs a second connection.
- On your watch, swipe to find the “Call,” “Phone,” or “Audio” setting and make sure it’s turned on. It may be called “Call Audio.”
- Now, go to your phone’s main Bluetooth settings (not the app).
- Look for a new, second device to appear. It might be called “G53-Audio,” “Watch Call,” or something similar.
- Tap to pair this device as well.
Once you have both “G53” (in the app) and “G53-Audio” (in your phone’s Bluetooth) connected, your watch is fully operational. You’ll be able to see notifications (from Connection 1) and answer calls (from Connection 2).
Part 3: The Notification Puzzle (And the “Texting” Question)
“My watch is connected, but I’m not getting texts!”
Welcome to the Permission Puzzle. Your watch doesn’t get texts. Your phone gets texts, and the app needs your permission to “read” that notification and “push” it to the watch.
You need to grant permission in two places:
- In the App: Go to the app’s “Notifications” or “Message Push” section. You will see a list of every app on your phone (SMS, WhatsApp, Facebook, etc.). You must manually toggle on every single app you want to receive notifications from.
- In Your Phone’s Settings: The app will need high-level “Notification Access.” Your phone will (and should!) warn you about this. You must allow it. The app also needs permission to run in the background, or your phone will “kill” it to save battery, and your watch will stop getting data.
Now, let’s answer that big question: “Can you text on the RUXINGX watch?”
Here’s the clear, simple answer: No.
Watches in this category are designed as notification mirrors, not mini-phones. You can read the incoming SMS or WhatsApp message, which is incredibly useful. But you cannot compose a reply, send a new text, or (usually) even see emojis.
This isn’t a bug; it’s a design choice to keep the device simple, affordable, and battery-efficient. The “Make/Answer Call” feature is for voice, not text.
Part 4: Your Health Data (What It Is and Isn’t)
Now for the fun part. Your watch is covered in sensors. The original RUXINGX G53 product page, for example, talks about heart rate, blood oxygen, and sleep. But what are you really measuring?

Heart Rate & Blood Oxygen (SpO2)
On the back of your watch, you’ll see little flashing green and red lights. This is an optical sensor called a photoplethysmograph (PPG).
- How it works (in simple terms): It shines light into your skin. Blood absorbs light. As your heart pulses, the amount of blood in your wrist changes. The sensor measures the reflection of that light to figure out your pulse. For SpO2, it uses different light (red/infrared) to see how much oxygen your blood is carrying.
- What it means for you: This is not a medical device. Do not use it to diagnose a condition. The value is in tracking trends over time. Is your resting heart rate (when you first wake up) generally going down as you get more fit? How does your heart rate respond during a walk? That’s the data that matters.
Steps & Activity
The watch uses an internal motion sensor (an accelerometer) to count steps. It’s looking for the rhythmic, back-and-forth swing of your arm.
- The “Stroller Test”: This is a perfect example of how it works. If you are pushing a stroller or a shopping cart, your arm isn’t swinging. Your watch will think you are standing still and will not count your steps. This is normal! For the most accurate count when pushing something, you might have to put the watch in your pocket (though you’ll lose heart-rate data).
- Sport Modes: The “70 Sports Modes” mentioned for the G53 are basically different-timers that assume a certain level of calorie burn for that activity. The “Yoga” mode doesn’t know you’re in downward dog, but it knows you’re active and tracks your heart rate in a way that’s different from the “Running” mode.
Sleep Tracking
This is a combination of all three sensors. The watch measures:
1. When you stop moving (accelerometer).
2. When your heart rate drops (PPG).
3. When your body is still, but your heart rate and breathing patterns suggest “REM” sleep.
It’s a fantastic tool for checking one thing: consistency. Are you getting 7-8 hours a night? Are you going to bed and waking up at roughly the same time? That’s the health-changing data you’re looking for.

Part 5: Making It Yours
You’re all set up. The data is flowing. Now you can personalize.
- Watch Faces: All the watch faces (like the 400+ options for the G53) are stored in the app, not the watch. Go to the “Device” section of the app, find “Watch Faces” or “Dial Gallery,” and pick your favorite. You can even upload your own photo on most.
- Bands: The RUXINGX G53 comes with three bands for a reason. The silicone bands are for exercise and sweat. The woven or metal bands are for style.
- Other Features: Explore the app! You’ll find “Sedentary Reminders” (to tell you to stand up), “Find my Watch,” and female health cycle tracking. All of this is controlled from the app.

Your “Final Exam” Checklist
You’re now a pro. Your watch is no longer a confusing piece of tech; it’s a tool.
- You found the right app by scanning the QR code.
- You connected the watch inside the app, not in your phone’s settings.
- You connected the “Audio” profile in your phone’s Bluetooth settings to enable calls.
- You went into the app’s notification settings and toggled on SMS, WhatsApp, and everything else you want to see.
- You understand your watch is for reading texts, not sending them.
- You’re looking for trends in your health data, not diagnosing yourself.
Congratulations. You’ve just mastered your new smartwatch.
