The MediBio Health and Fitness Tracker is marketed as a budget-friendly wearable that tracks heart rate, steps, sleep, temperature, blood pressure, and oxygen levels. But users quickly discover that the device is difficult to set up, lacks a working official app, and often arrives with no charging cable or functional instructions.

Based on dozens of real user comments, this product is fundamentally flawed. It often arrives with no charging cable, lacks any real instructions, and cannot be reliably synced to a functioning app—making it impossible to use as intended. Many users reported broken units, language issues, or virus alerts when attempting to set it up.

This guide combines the original MediBio manual, online research, and independent user reviews to give you the most accurate, step-by-step instructions available.

What Is The Medibio Health And Fitness Tracker?

The Medibio Health and Fitness Tracker is a small electronic device called a smart band that’s worn on your wrist and designed to help you monitor health and fitness progress by using basic technology to count your steps and measure things like heart rate and blood pressure. 

The data collected by the tracker is then sent wirelessly to an app on your smartphone or tablet where it can be analyzed in real-time. This allows you to track your progress over time and make adjustments as needed in order to reach your health and fitness goals.

User reality:

• Many users reported the official app doesn’t exist, is full of broken links, or prompts virus and subscription warnings.
• A few succeeded using the DayBand app instead—“synced and worked fine”.

What the band is meant to do

• Count daily steps and estimate distance
• Estimate calories burned
• Measure heart rate during the day or on demand
• Attempt basic blood pressure and blood oxygen readings
• Track nightly sleep
• Show time, date, battery and step count on the main screen
• Offer simple sport modes such as walking, running or cycling
• Vibrate for calls or messages when paired with an app

Important facts before you start

• The band is not a medical device and readings are not clinically validated.
• Time and date cannot be set on the wristband itself. They only update when the band is paired with an app and synced.
• Most units do not include a separate charging cable because the USB plug is built into the band.

How To Use Medibio Health And Fitness Tracker

Use this section as a quick overview of daily operation. Later sections give detail for each step.

To use the MediBio Health and Fitness Tracker, start by removing one side of the wristband to expose the hidden USB charging prong—this is how the device powers on, as it has no physical power button. Plug it directly into a USB port to begin charging. 

Once powered, pairing the device with a phone can be tricky, as the official app appears to be defunct or unsafe, with multiple users reporting virus warnings and broken download links. However, some users have successfully synced the tracker using the DayBand app on Android, which allows access to basic features like step counting, heart rate monitoring, and sleep tracking. 

Setup instructions are not included in the box, and there is no official website or tech support available, so users must rely on trial and error. If you’re able to charge the device and connect it via DayBand, you can adjust settings like units and time through the app—though not all users have had success with this.

How To Charge A Medibio Health And Fitness Tracker

The most common problem users have is simply figuring out how to charge the tracker. Follow these instructions exactly.

Despite what the box suggests, the MediBio tracker does not require a cable.

Correct Charging Method

1. Remove one strap

• Identify the charging side. 
• Look at both ends of the band where the strap meets the body.
• On one side you will see a slightly looser joint. This side hides the USB plug.
• Remove one half of the strap
• Hold the tracker body firmly in one hand.
• With the other hand, pull the strap straight down and away from the body until it slides off. (Do not twist sharply to avoid breaking the plastic.)
• Expose the USB charging plug
• This is designed to plug directly into a USB port. No separate cable is needed.

2. Insert directly into a USB port

• Laptop
• USB phone charger
• Power bank
• PC USB port

The metal charging pins must face upwards inside the USB slot.

3. Charging indicator

• The screen should turn on and show a battery symbol or charging animation.

If nothing appears:

• Flip the device and reinsert
• Try a different charger
• Clean the metal contacts
• Make sure the correct strap was removed
• If it still doesn’t charge the tracker is defective — extremely common with this model.

4. Leave it connected for at least 2 to 2.5 hours the first time.

User tip: If you store the band for a long time, give it a top up charge every three months so the battery does not die completely.

How To Turn On Medibio Health And Fitness Tracker

Generic online instructions sometimes talk about a power button on the side of the watch. The MediBio band does not have an external power button. It turns on automatically when it has enough charge.

To turn it on correctly:

1. Charge the band until you see a battery icon on the display.
2. Remove it from the USB port after it has charged.
3. Tap the touch area at the bottom of the screen. (The tracker has no power button)
4. A single tap wakes the screen.
5. Repeated taps move between modes.

If the band does not respond to tapping even though you saw the battery icon earlier, reconnect it to USB for another 30 minutes and try again.

If the screen never lights up while connected to USB, the band is not receiving power and is most likely a dead unit.

Medibio Health And Fitness Tracker Set Up

Setup has three main parts:

• Charge and power on the tracker.
• Install a compatible app on your phone.
• Bind the tracker to the app so that time, date and data can sync.

Once these steps are complete, the band will display correct time and begin recording steps, sleep and other data in the background.

Medibio App Download

There is a lot of confusion around which app to use. Some packages mention an official Medibio app or include QR codes that lead to broken or unsafe links. You can safely ignore those.

For most MediBio smart bands, the best options are:

Wearfit 2.0

Download Wearfit 2.0 only from official stores:

• Android: https://play.google.com/store/apps/details?id=com.wakeup.wearfit2
• iOS: https://apps.apple.com/app/wearfit-2-0/id1291710737

DayBand (Android only)

Download DayBand from Google Play:

• Android: https://play.google.com/store/apps/details?id=com.topstep.dayband

When you install either app, it will ask for permissions such as Bluetooth, Location (on Android), notifications and background activity. These allow the app to search for the band, keep the connection open and show alerts on your wrist.

If you are concerned about privacy, you can grant only the minimum permissions you are comfortable with, but connection and notifications may not work fully.

How to Connect Your Medibio Health And Fitness Tracker

Once the band is charged and an app is installed, follow this connection process carefully. Pair from inside the app, not from your phone’s Bluetooth menu first.

1. Turn on Bluetooth on your phone
   1. On Android, also make sure Location is turned on because the system uses it during Bluetooth scanning.

2. Open Wearfit 2.0 or DayBand
   1. Create an account or sign in if needed.

3. Go to the device binding section
   1. In Wearfit 2.0 this is usually under the Device tab or under Profile → Add device.
   2. In DayBand it is under the Device section.

4. Start scanning for devices
   1. Keep the band close to the phone, within about 20 to 30 centimeters.
   2. Wait while the app searches.

5. Select the correct device
   1. It might appear as Smart Band, Bracelet, Y39 or another generic name.
   2. Tap the device name to start pairing.

6. Confirm any pairing prompt
   1. Accept the Bluetooth pairing request when your phone asks.
   2. The app should show the device as connected.

7. Wait for first sync
   1. Within a few seconds the correct time and date should appear on the band.
   2. The steps and health data fields in the app should start filling with numbers from the band.

If the band does not show up in the device list:

• Make sure the band has enough charge and the screen can turn on.
• Move away from other Bluetooth devices that might interfere.
• Close and reopen the app, then scan again.
• On Android, check that the app has Location permission, as this often blocks scanning if it is turned off.
• If the band still cannot be found after several attempts, it may not be supported by that app or may be faulty.

How to Set Time

Time and date cannot be adjusted directly on the MediBio band. There are no time setting menus on the watch itself.

To set the time correctly:

1. Connect the band to Wearfit 2.0 or DayBand using the steps above.
2. Once the device shows as connected, keep the app open on the main screen for a minute.
3. The band reads the phone’s current time and date and updates automatically.
4. If the time is still wrong after one minute:
   • Pull down in the app to trigger a manual sync if that option exists.
   • Disconnect and reconnect the band.
   • Restart both the phone and the band (by plugging the band out of and back into the charger)

Whenever you move to a new time zone or correct the time on your phone, open the app again while the band is nearby. It will resync to match your phone.

Medibio Blood Pressure Monitor Instructions

The blood pressure feature on the MediBio tracker is intended only for casual wellness tracking. It does not replace a proper upper arm blood pressure monitor and is not approved as a medical diagnostic tool.

To use it as safely and accurately as possible:

1. Wear the band correctly

• Place it about one finger width above your wrist bone on the inside of your arm.
• Fasten the strap so it is snug but not painfully tight.
  

2. Sit still for a few minutes
   • Rest your arm on a table at roughly heart level.
   • Avoid talking, moving or crossing your legs during the reading.
     
3. Start a blood pressure reading
   • Tap through the screens on the band until you see the blood pressure symbol.
   • Press and hold the touch area to begin measurement.
   • Keep your wrist still until the numbers stop changing.
     
4. Read the result
   • The display will show two values, similar to 120 over 80.
   • You can also open the app to see a history of previous readings if syncing works.
     
5. Interpret with caution
   • Use the readings only as a rough indication of trends.
   • If the numbers look very high or very low, do not rely on the band. Check again with a validated home monitor or speak to a healthcare professional.

User tip: If the band repeatedly shows the same blood pressure results regardless of what you do, assume the readings are not accurate.

Medibio Health And Fitness Tracker Manual & Instructions

Use this section as a checklist of everyday functions and troubleshooting.

Daily use:

• Tap once to wake the screen.
• Tap repeatedly to move between time, steps, distance, calories, heart rate, blood pressure, blood oxygen, sport modes, sleep and settings icons.
• Press and hold on a screen to start a measurement or enter a mode.
• In sport mode, press and hold to start tracking and press again to pause or stop.

General tips and reality based advice:

• Always start by charging the band fully before trying to pair it.
• If the band stops syncing, unbind it inside the app and bind it again instead of only deleting the app.
• Remember that sudden changes to step count, heart rate or blood pressure may reflect sensor errors, loose fit or motion, not true health events.
• For long term tracking, focus on overall trends over weeks, not single readings.
• If you ever see suspicious download links, pop up ads or strange QR codes, ignore them and return to the official Wearfit 2.0 or DayBand links listed above.

Reality-based tips:

• The manual isn’t clear enough: there is no power button—device powers on after charging.
• Charging requires partial removal of the band.
• No reliable official app—best success has been with DayBand on Android.
• Company support and website are defunct; manual links lead nowhere

Conclusion

The MediBio Health and Fitness Tracker is best understood as a very basic wellness gadget. It can work reasonably well for counting steps and giving rough estimates of sleep and heart rate, but it is not a medical device, and setup is more confusing than it should be.

To get the most out of it:

• Charge it correctly by exposing and using the built in USB plug.
• Accept that there is no physical power button and that charging is what turns it on.
• Use Wearfit 2.0, or DayBand on Android, as your main app and install them only from the official app stores.
• Pair the tracker from inside the app so that time, date and data can sync.

Treat heart rate, blood pressure and blood oxygen results as rough guides and always double check important readings with proper medical equipment.

If you find that your unit never charges, never shows in the app or constantly disconnects, it is reasonable to return it or switch to a better supported tracker. Established brands that work with serious platforms, including the clinical software built by Medibio Limited, will give you more reliable data and a far smoother experience over time.

Users appreciated the concept, but many describe it as poorly built, useless without an app, or full of manufacturer errors. Reality-check suggests most people see better results with established brands—Mi Band, Amazfit, Fitbit Inspire—especially if you value reliability, tech support, and app integration.
