Hi! I see you're noticing a change in the bone mass criteria in the Feelfit app around October 2023, specifically from a threshold of less than 5.6lb being "inadequate" to now greater than 4.6lb being considered "above average." That does sound like a notable shift, and it's important to understand so you can interpret your measurements correctly.

Could you share a little more about where exactly you're seeing this criteria change? Is it a notification or update within the app, or perhaps in your measurement reports? Also, are you comparing your readings over time, or did you just notice the new thresholds recently?

In the meantime, I can explain that apps like Feelfit sometimes update their health metric standards based on new research or recalibration of device sensors to improve accuracy. The different thresholds might reflect refined categorization or changes in population data used as references.

Here’s what we can do next to clarify and adjust:

1. Check App Update Notes: Look in the app store or Feelfit app’s update history for October 2023—developers usually note changes to measurement criteria or algorithm updates.

2. Review Your Profile Settings: Sometimes the app adjusts criteria based on age, gender, or other profile data. Confirm your profile info is up to date.

3. Recalibrate Your Device: Sometimes recalibration or updating the app resets measurement standards. Try syncing your device again and see if the categories adjust.

4. Contact Feelfit Support: If change details aren’t clear, reaching out to Feelfit support can clarify exactly what the new bone mass criteria mean for your readings.

Would you like me to walk you through checking your app update notes and profile settings step-by-step? Or assist you with recalibrating your device on AndroidOS 10? That way we can ensure your bone mass data interpretation is accurate and useful.
