Hi there! I understand your Withings app version 7.6.0 is either not detecting your blood pressure monitor (BPM) or it crashes on both Android and iOS 7.0 devices. Let me help you get this sorted out.

To start, could you tell me which specific BPM model you're using? Also, have you tried any troubleshooting steps so far, like restarting Bluetooth or the app itself?

Meanwhile, here’s a step-by-step approach we can follow to tackle this:

1. Restart Bluetooth and the BPM device:
- Turn off Bluetooth on your phone and then turn it back on.
- Press and hold the button on your BPM for about 3 seconds to turn it off, then turn it back on.

2. Force close and reopen the Withings app:
- Close the app completely (remove it from recent apps).
- Open it again and check if the BPM is detected.

3. Check the app permissions:
- Ensure the app has the necessary permissions to access Bluetooth and location (required by some Android versions).
- On iOS, make sure Bluetooth access is allowed in Settings.

4. Try syncing the BPM manually:
- While the Withings app is open, start the BPM and see if it syncs.

5. Update or reinstall the app:
- Check if there's an update available for the Withings app.
- If problems persist, uninstall and then reinstall the app.

If after these steps the app still can’t see your BPM or crashes, the issue might be more specific to the app version or device compatibility.

Please let me know what happens after trying these steps, or if you have already tried some, which ones, so I can offer further guidance.

Also, if you want, I can share some links to official Withings support resources that address BPM device connection issues. Would that be helpful?
