## What is Membrane Health?

Membrane Health helps you know how stable all your systems are today.

Built on Apple Watch and Apple Health, Membrane Health reads the signals your watch already measures and computes how coherently your body is holding together under today’s load. Your result is a clear daily read — go, caution, or recover — calibrated to your own physiology.

Membrane Health is not another single wellness score. It reads your whole system at once: heart, sleep, breath, metabolism, temperature, oxygen, movement, recovery, and activity, organized against your own rolling 28-day baseline.

The free home screen gives you an honest assessment at a glance:

• Daily status and recommendation
• Go, caution, or recover
• Watch-out areas for the day
• Mode detection: Sleep, Stress, Rest, Flow, or Nova
• Membrane Resilience: how much buffer remains between today’s load and your edge

Basic opens the reading into more depth:

• Personalized baselines
• Health Dimensions
• Body Load
• Raw Metrics
• Coherence, timing, phase, amplitude, drift, and recovery context
• Stability, ETA, and capacity tracking

Pro is for when you want to see what is driving the number:

• Live Pro Dashboard
• Membrane Integrity
• Capacity Budget
• Tolerance
• Health Potential
• Energy
• Manifold Integrity across autonomic, circadian, metabolic, and mechanical systems
• My 28/60/90 Analysis
• Professional Sharing for clinicians, coaches, trainers, or other trusted professionals

Membrane Health is built around timing: not just what your body is doing, but when. It helps you see whether today’s load is organized, where recovery is needed, and how your systems are holding together through change.

Your data stays where it belongs. Membrane Health reads from Apple Health with your permission. Fieldflux does not sell your personal information. Sharing is consent-driven and only happens when you choose it.

Membrane Health is not a medical device and does not diagnose, treat, or prevent disease. It surfaces patterns in your own health data to support better day-to-day decisions about effort, recovery, and timing.

For best results, use Membrane Health with an Apple Watch worn consistently, especially overnight.

### 5/5 — A great way to start the day!

*2026-08-24*

Gathers my metrics from Apple Health Kit in the morning then interprets and provides guidance in a way that is easy to understand. If you’re someone who loves tracking metrics to optimize performance, integrating information in a meaningful way, you can dive deep into the information provided- or you can keep it simple. Amazing app, one of a kind! Great way to know your potential in real time.

### 5/5 — The guidance i’ve been looking for

*2026-08-22*

This app helps consolidate your health information and provides real insight and guidance into your specific rhythms. Instead of trying to sort you into “type” this app analyses your individual trends and makes personalized recommendations. This is incredibly helpful because instead of just presenting you the data and numbers, it puts into context what they actually mean for your day. I have previously relied on Oura, but this gives a lot more detailed information and guidance. One of my favorite features it’s its ability to help you maximize your energy by being most active during the time of day that is best for your own body! If you would like more actionable information from your wearable tech, you should try this out. If you’re interested in more than just the numbers, and what to learn how to really live in your rhythm, this is a great place to start.

### 5/5 — Extremely helpful

*2026-08-19*

After using many health apps, Membrane Health stands out because it doesn't just throw raw data at you - it explains what your body can actually support today. Being able to see resilience, timing, and load capacity at a glance gives instant clarity on when to push and when to let the body adapt (even against what I think I should be doing). Decision based on metrics helps me plan my weekly workouts. Easily the best Apple Watch companion apps i have found.
