Safety

Strobotorch can produce bright and flashing light.

The app must show the exact visible warning phrase: not for human consumption.

It is a flashlight signaling tool. It is not a hallucination, meditation, psychedelic, medical, relaxation, brainwave-synchronization, or entrainment product.

It is also independent from Till Holzapfel’s scientific-advisor work for Brain Candy. Strobotorch is Android tooling for torch/camera APIs and visual signal experiments, not a Brain Candy product or research deliverable.

Do not use the flashing modes if you have photosensitive epilepsy, seizure history, light-triggered migraine, severe light sensitivity, visual snow/HPPD-like symptoms, or are sensitive to flashing light. Do not point flashing light at other people. Do not stare into the flashlight, especially directly, close up, in a dark room, or while intoxicated or otherwise impaired.

Stop immediately if you feel discomfort, dizziness, nausea, headache, eye strain, anxiety, confusion, afterimages, trails, visual snow-like static, disorientation, panic, or any seizure-like symptom.

Default Direct-Viewing Policy

• Maximum direct-viewing flash rate: 3 flashes per second.
• Maximum direct-viewing duration: 10 minutes.
• Foreground Activity only.
• Torch stops when the app leaves the foreground.
• Torch stops when the session ends, fails, or is canceled.

Point-Away And Lab Modes

Point-away and lab diagnostics are for measuring requested API behavior on a device. They are not for looking at directly and are not enabled as the normal user path. The app can request high-rate point-away diagnostics up to 60 Hz, but those requests are not claims about actual optical LED output.

Fractal-dimension controls are point-away signal-shaping controls. A reported Higuchi D or PSD beta value describes the app’s requested command trace, not what the phone’s LED optically emitted.

Audio-Reactive Safety

Audio-reactive modes do not map raw audio samples directly to torch commands. The app first computes low-rate features, then applies smoothing, safety caps, and command-rate limits.

• Calibration starts with torch preview off.
• Direct-viewing audio-reactive flashing remains capped at 3 flashes per second.
• Silence turns direct-viewing preview off.
• Audio capture and torch preview stop when the Activity leaves the foreground.
• Torch output in audio-reactive mode requires explicit point-away acknowledgement before the switch is enabled.
• Point-away audio-reactive output can use the selected requested frequency and brightness range, including requested rates up to 60 Hz.
• Fractal-dimension analysis in audio-reactive mode runs on the mapped command trace and is not an optical measurement.

Claims Boundary

This project does not make medical, therapeutic, relaxation, meditation, psychedelic, hallucination, brainwave synchronization, gamma stimulation, fractal phototherapy, or entrainment claims. It is a transparent Android torch-control and device-variance project.
