Hello! I see your BIGGERFIVE app is not working after you used swimming mode and exposed it to a sauna. Let me get a few more details so I can help you better:

1. Which BIGGERFIVE device or model are you using?
2. When you say "it's not working," do you mean the device itself is unresponsive, or the app on your iPhone is not connecting or showing data?
3. Have you tried restarting your iPhone or reinstalling the BIGGERFIVE app yet?

From what I know, many BIGGERFIVE devices are not designed to be used in swimming or sauna environments due to water and heat sensitivity. Excessive moisture or heat can sometimes cause the device to malfunction temporarily or permanently. But let's try a few steps to see if we can get it back working:

### Step-by-step to troubleshoot:

1. Dry and cool down your device:
After sauna exposure, make sure to completely dry and cool down your device to room temperature before turning it back on.

2. Force restart the device:
- For the device, try pressing and holding the power button (or combo buttons depending on model) for about 10-15 seconds to force a reboot.

3. Restart your iPhone and the app:
- Close the BIGGERFIVE app fully from the app switcher.
- Restart your iPhone (hold the side button and volume up/down until you see the power off slider).
- Then reopen the app and try reconnecting.

4. Check Bluetooth connection:
- Ensure Bluetooth is active on your iPhone (Settings → Bluetooth).
- If the device isn’t appearing under paired devices, try re-pairing it via the app.

5. Check for app and iOS updates:
- Go to the App Store and see if there’s an update for BIGGERFIVE app.
- Also, ensure your iPhone’s iOS is up to date (Settings → General → Software Update).

If these steps don’t help, it’s possible the water or heat damaged the device internally. Unfortunately, BIGGERFIVE states that some of their waterproof devices are not suitable for swimming or sauna use3 9.

Please let me know the answers to my questions, and if you tried any of the above so far. That way, I can provide more targeted help!
