Hi there! I understand your Da Fit watch isn’t connecting to your iPhone. Let’s work through this together to get you up and running.

First, to better assist, could you tell me if you’ve already tried connecting before? For example, did you already enable Bluetooth on your iPhone or try restarting the devices? Also, do you see the watch in your iPhone’s Bluetooth list, or is it not showing up at all?

While you gather that info, here’s a straightforward step-by-step that tends to resolve many connection issues:

1. Toggle Bluetooth Off and On:
Go to your iPhone's Settings > Bluetooth, turn Bluetooth off, wait a few seconds, then turn it back on again.

2. Restart Both Devices:
Restart your iPhone and your Da Fit watch. This refreshes their system and clears minor glitches.

3. Unpair and Re-pair the Watch:
- Open the Da Fit app and unpair or forget your watch if it’s already paired.
- On your iPhone, go to Settings > Bluetooth, find the watch, and tap “Forget This Device” if it’s there.
- Then, in the Da Fit app, try pairing the watch again following app prompts.

4. Lock Da Fit App in Background:
After connecting, on iPhone, swipe up to show the app switcher and make sure the Da Fit app stays locked in the background (not closed), so the connection keeps active.

5. Check for App and Firmware Updates:
Ensure the Da Fit app is updated to the latest version in the App Store. Also, check within the app if your watch firmware has updates and install them.

If after trying these your watch still won’t connect, please let me know exactly where the process fails—does the watch not show up on Bluetooth? Does the app give an error? Any detail will help me assist you further.

Looking forward to your reply!
