Body composition and weight tracking

Include sections to track body weight, body fat percentage, and lean mass trends over time to monitor progress alongside nutrition and activity.

Change body fat percentage

I would like to see the high body fat range change from obesity to high or very high. While obesity is associated with high body fat, BMI is a better indicator for obesity. I for example use a smart scale which is known to be potentially inaccurate for body fat. I am considered obese due to my high body fat reading however my BMI is not in the obese category. For reference I’m 5’10 190 pounds and I am a male.

I would like to view the body mass index (BMI/BMI) in the BIOLOGY dashboard

Request: Expanded HealthKit Body Composition Metrics (Visceral Fat, Segmental Muscle, Hydration, etc.)
Chris Johnson
Hi Bevel team & community,
As more of us adopt smart body scanning scales and similar devices, the data they provide is far richer than what HealthKit currently allows apps to store. Right now, Apple Health supports only a handful of body composition metrics (Weight, BMI, Body Fat %, Lean Mass, Waist Circumference, Height).
But modern scales can deliver dozens of clinically relevant metrics:
• Visceral fat % / rating
• Skeletal muscle mass
• Segmental muscle/fat (arms, legs, trunk)
• Bone mass
• Total body water % / hydration
• Muscle-to-fat ratio
• Metabolic age
• Basal metabolic rate (BMR)
• Phase angle (bioelectrical impedance)
Unfortunately, these don’t have first-class fields in HealthKit today — meaning apps like Bevel (and others in the ecosystem) can’t write them in a standardized way.
⸻
Why This Matters for Bevel:
• Better sync & storage: Users who rely on Bevel as their hub could see the full picture of their body composition, not just weight + fat %.
• Cross-app compatibility: Other apps reading from HealthKit would also get access to the richer data.
• Future-proofing: As body scanners and smart scales evolve, Bevel will be positioned as a leader in full-health data integration.
⸻
What We Can Do:
I’ve already submitted a developer feature request to Apple asking them to expand HealthKit’s supported metrics:
Apple Developer Forums thread here: https://developer.apple.com/forums/thread/802918
If you’re interested in seeing Bevel support these advanced metrics, I’d encourage you to:
1. Upvote/comment on that Apple Developer Forums post so Apple sees there’s wide demand.
2. Add your voice here in Bevel’s feedback forums, so the Bevel team knows it’s a priority for us.
⸻
Summary: Adding these HealthKit metrics would let Bevel take advantage of the new wave of body scanning tech and give users a truly complete health dashboard.

Body dimensions

It would be a nice addition to be able to fill in measurements of different parts of the body. Such as the arms, legs, chest, stomach, etc.

Shall we park segmental body analysis under this thread or create a separate one all together?

Automatic lean body mass calculation
Simon Rejzek
It seems like a feature that should’ve already been in Bevel, but isn’t. Bevel should automatically calculate my lean body mass of off my body fat percentage and weight. This wouldn’t even take that long to implement in the app (est. less than a day).

Add Muscle Body Mass to Bio
Panagiotis Pentsidis
in ihealth app i have that metric how can be shown in the app? Maybe u can plan to add that too in biology section

Hi Koan, this is something we can add in the future as a variable pulled through Apple Health. I'll add it to the roadmap!
Koan
Hi Amanda thank you very much! As far as I know by now Apple Health does not track the visceral fat but maybe there are ways to incorporate devices from WithingS like you did with the brands for bloodglucose but even be able to tracking it manually would be awesome!
