Frequently Asked Questions
Q: What is BIOLOCK?
A: BIOLOCK is a wellness tool for iPhone and Apple Watch. It reads three signals — voice, motion, and heart-rate variability — and combines them into a single steadiness score between 0 and 1. The score updates ten times per second.
Q: How does the app work?
A: BIOLOCK runs a closed measurement loop at 10 Hz on the Apple Watch. It computes a steadiness score from your voice, motion, and HRV signals. When the score becomes unsteady, the app computes a small corrective signal. A session completes when the score holds at 0.85 or higher with low drift.
Q: Is BIOLOCK a medical device?
A: No. BIOLOCK is a wellness and research tool. It does not diagnose, treat, cure, or prevent any disease. Always consult a licensed clinician for health concerns.
Q: What hardware do I need?
A: iPhone 12 or newer running iOS 17 or later, and Apple Watch Series 10 or newer running watchOS 11 or later.
Q: Does the app need internet?
A: No. BIOLOCK contains no networking code. Nothing leaves your device. This is enforced at compile time by a build-phase script that fails the build if any networking symbol is present in the source tree.
Q: Do I need an account?
A: No. There is no sign-up, no login, and no cloud sync. The app starts working as soon as you open it.
Q: Where are my sessions saved?
A: Sessions are saved locally on the device that ran the session, as JSON files in the OS application sandbox. You can view them in the Result and History screens on iPhone or in brief form on Apple Watch.
Q: Can I export my sessions?
A: Yes. The app provides a local file URL for each SessionRecord. You initiate any sharing through the native OS share sheet. The app itself does not transmit anything.
Q: Is there an in-app purchase or subscription?
A: No. v1 is free with no in-app purchases.
Q: How do I uninstall?
A: Press and hold the BIOLOCK icon on your Home Screen, then select Remove App. Removing the app deletes all locally-stored session records.
Q: Where can I see the patent and citations?
A: Visit www.myyogameditation.com/biolock/citations.
Q: Why does the app use a 0.85 threshold?
A: 0.85 is the closure threshold specified verbatim in the patent (Patent Application No. 328645, §6.6). The app does not compute or claim a clinical significance for this value; it is the locked closure constant of the patent specification.
Q: Why does the app use prime numbers for timing?
A: The patent specifies that the correction emission is gated to prime-indexed temporal windows (Patent §6.4). This is part of the patented method.
Technical requirements
-
iOS 17.0 or later (iPhone 12 or newer)
-
watchOS 11.0 or later (Apple Watch Series 10 or newer)
-
HealthKit permission (for reading HRV)
-
Motion & Fitness permission (for reading motion stability)
-
Microphone permission (for voice input)
Troubleshooting
The Watch app won't start a session
-
Open the iPhone Health app and make sure HealthKit permissions are granted to BIOLOCK.
-
Open Settings → Privacy & Security → Motion & Fitness and make sure BIOLOCK is enabled.
-
Open Settings → Privacy & Security → Microphone and make sure BIOLOCK is enabled.
The session never reaches closure
The four conjuncts must all hold simultaneously at a prime-indexed temporal window. Try holding the device steady and breathing calmly. Sessions typically complete in 1–3 minutes.
Heart rate readings are zero or missing
Make sure the Apple Watch is worn snugly on your wrist and that you've granted HealthKit permission for heart rate data.
