1. What Causes HiWatch / HiWatch Pro Not Connecting?

There are several potential causes:

• Bluetooth permission not enabled
• Watch already paired to another device
• App installed incorrectly
• Wrong “time zone” or “location permission”
• Phone’s Bluetooth cache issues
• Battery saver interrupting connection
• Outdated firmware
• Too many devices stored in your phone’s Bluetooth history

Many new users think their watch is broken, but 95% of issues can be fixed with simple settings.

2. Before You Start: Quick Checklist

Before diving into advanced fixes, confirm the basics:

Make sure:

• Bluetooth is ON
• Watch is at least 30% charged
• Phone is within 1 meter of the watch
• You are connecting inside the HiWatch app, not only through the phone’s Bluetooth page
• The watch is not paired to another phone
• The HiWatch app has Location + Bluetooth + Notification permissions

If all these are fine, start the connection steps below.

3. How to Download the HiWatch App Properly

Incorrect app installation often causes connection failures.

✔ Recommended (official download):

👉 https://hiwatch.app/
(This avoids fake apps, wrong versions, and malware.)

Install the correct app:

• HiWatch / HiWatch Pro → “HiWatch” official app
• HiWatch Plus → branded variant compatible with your device

4. How to Connect HiWatch on Android

Follow these steps:

Go to:
Settings → Apps → HiWatch → Permissions

Enable:

• Bluetooth
• Nearby Devices
• Location
• Notifications
• Background activity

If Location permission is off, Android will NOT allow Bluetooth scanning.

Step 2 — Turn Off Battery Optimization

Android often kills smartwatch apps.

Go to:
Settings → Battery → App battery management → HiWatch → Allow background activity

Step 3 — Connect Through the HiWatch App

Do NOT pair through Bluetooth settings first.

Open:
HiWatch App → Device → Add Device → Search

Select your watch model:

• HiWatch
• HiWatch Pro
• HiWatch Plus

When a pairing request appears, tap Pair / Allow / OK.

Step 4 — If It Still Fails

Try clearing Bluetooth cache:

Go to:
Settings → Apps → Show system apps → Bluetooth → Storage → Clear Cache

Reboot your phone.

5. How to Connect HiWatch on iPhone

iOS normally pairs smoothly. If it doesn’t:

Step 1 — Enable Bluetooth, Wi-Fi, and Background App Refresh

Go to:
Settings → General → Background App Refresh → ON

HiWatch relies on this for syncing.

Step 2 — Allow Permissions

Settings → HiWatch → Enable:

• Bluetooth
• Location
• Notifications
• Mobile Data

Step 3 — Connect via App

Open:
HiWatch App → Device → Add Device

Select your watch when it appears.

Step 4 — Fix iPhone Not Showing the Watch

Go to:
Settings → Bluetooth → Forget All Old Smartwatch Devices

Reboot your iPhone.

6. Fix HiWatch Not Showing Up in Bluetooth

If your watch does not appear when scanning…

Try:

✔ A. Restart the Watch

Long press power → Restart.

✔ B. Restart Phone

Simple but effective.

✔ C. Reset Bluetooth (Android Only)

Settings → System → Reset Options → Reset Wi-Fi, Mobile & Bluetooth

✔ D. Turn On Location Permission

Required for scanning devices.

✔ E. Remove Distance

Place the watch right beside the phone.

7. Fix HiWatch Pro Disconnecting Randomly

If the watch keeps disconnecting:

✔ Tip 1 — Lock the App in Background (Android)

Swipe up → Hold HiWatch → Lock icon (prevent closing).

✔ Tip 2 — Avoid Using Battery Saver

Battery saver cuts Bluetooth automatically.

✔ Tip 3 — Keep App Updated

Outdated versions cause unstable pairing:

8. Reset & Re-Pair Your Smartwatch

When all fails, reset the watch:

On the watch:
Settings → Reset → Confirm

Then:

1. Turn off Bluetooth on your phone
2. Forget the watch in Bluetooth list
3. Re-open the HiWatch app
4. Re-pair again

This solves 80% of pairing issues.

9. Firmware Update Guide

Outdated firmware can break Bluetooth.

In the HiWatch App:
Device → Firmware Update → Download & Install

Do not turn off your watch or phone during updates.

10. When Nothing Works

If you’ve tried everything:

✔ Check if your smartwatch is a clone version

Some sellers distribute modified firmware versions.

✔ Try a different phone

If it connects on another device → your phone’s Bluetooth stack is the issue.

✔ Contact the seller

Or return/exchange the device.

11. Final Tips to Keep Connection Stable

• Keep your phone’s Bluetooth ON
• Allow HiWatch to run in background
• Disable battery saver
• Update firmware regularly
• Restart your phone weekly
• Keep the watch within 10 meters
• Avoid connecting too many Bluetooth devices at once
