Hi! I see your QWatch Pro app won't turn on despite the device being fully charged. Let’s try a few things to get it working again.

First, can you confirm if you mean the QWatch Pro device (the watch) itself is not turning on, or is it specifically the app on your Windows device that’s not opening? This will help me guide you better.

Assuming you are talking about the watch device not powering on fully, here are some steps you can try:

1. Force Restart the Watch: Press and hold the power button (or the main button) for around 10-15 seconds. Sometimes this forces the device to reboot even when it appears stuck.

2. Check the Charger and Cable: Even if it shows fully charged, ensure the magnetic charger and the back of the watch are clean. Dirt or residue can interrupt charging or power signaling.

3. Reconnect the Charger: Place the watch on the charger again and see if the logo or any screen appears. Sometimes, the watch needs to detect the charger before powering on.

4. Try a Different Power Source: Use a different USB port or charger adapter to rule out issues with the charging source.

5. Check for Physical Damage: Make sure there's no visible damage to the watch or charger port that might be causing the problem.

If you are referring to the QWatch Pro app on your Windows device not opening:

- Try closing the app completely (use Task Manager if needed) and restarting your PC.
- Make sure your Windows 10 is up to date.
- Reinstall the QWatch Pro app to fix any corrupted files.
- Check your internet connection, as the app may need to connect to servers.

Let me know which scenario applies or if you have already tried any of these steps! We can take it from there.
