How it differs
It never says "ghost detected"
There are four verdicts — explained, uncertain, unexplained, and high-confidence anomaly — and nothing beyond them. A spike that lines up with you turning your body, a passing lorry, a fridge compressor or a change in air pressure is labelled explained, because it is.
Three scores, never averaged
Anomaly strength, evidence confidence and evidence independence are reported separately. Averaging them would let a strong reading from one unreliable sensor look like solid proof; kept apart, you can see that it is one loud number with nothing corroborating it.
Absent sensors stay absent
Phones vary. If your device has no barometer, the app says so and drops that line of evidence — it does not fabricate a plausible-looking reading or quietly substitute another sensor.
Your recordings stay on your phone
Sessions, audio and sensor traces are stored on the device and analysed there. The only thing this server ever holds is your email address, so that you can sign in — and you can delete the account, and everything attached to it, from inside the app.
What it cannot do
No phone sensor detects the supernatural, and this app does not claim to. What it can do is measure the physical environment carefully, record what it measured, and be rigorous about which readings have a mundane explanation. Anything left over is labelled unexplained — which means exactly that, and nothing more.
