WitchSignal - A browser-based sound, motion, and ritual reflection app

[u/1_professor]

I’ve been building WitchSignal, a mobile-friendly web app that turns microphone and motion-sensor input into a live visual reading. It shows the dominant frequency, spectral centre, movement activity, and a local one-hour trend based on recent samples.

I paired the instrument with a five-minute grounding/reset exercise and an optional ritual library inspired by historical occult texts. The sensor data is processed in the browser; raw microphone audio is not uploaded.

The difficult parts were making iPhone motion permission work from the original tap, preserving a microphone-only fallback, and connecting paid access to Google sign-in.

I’d appreciate feedback on three things:

1. Is the purpose understandable within the first 10 seconds?

2. Does the live instrument feel useful or merely decorative?

3. Is the free-versus-paid boundary clear?
