Measure real magnetic-field changes with SpiritTrace, a paranormal EMF instrument powered by your iPhone’s built-in magnetometer. REAL SENSOR. NO SCRIPTED SPIKES. The meter reacts to genuine magnetic-field readings from the same sensor used by your phone’s compass. Bring it near speakers, wiring, motors, magnets, metal, and electronics to see the field respond in real time. FOUR SENSOR-DRIVEN DISPLAYS Switch between Analog, Digital, 5-Bar, and Dual displays. Every face uses the same live sensor data. CAPTURE THE MOMENT Export the previous 15 seconds as a shareable evidence clip with readings, peak level, graph, and timestamp. FEEL EVERY CHANGE Optional Geiger-style audio and haptic feedback intensify with the field, so you can investigate without watching continuously. BUILT FOR PARANORMAL EXPERIMENTS Use SpiritTrace for ghost-hunting atmosphere, field experiments, and exploring how everyday objects affect the magnetometer. IMPORTANT SpiritTrace measures magnetic-field strength. It cannot verify paranormal activity or identify hazardous electromagnetic radiation. It does not replace professional safety equipment. Paranormal interpretation is for entertainment. SUBSCRIPTION The complete app requires an active subscription or introductory trial. Eligible new yearly subscribers receive three days free.

Dead Channel is a spirit box instrument built around eight voice banks. Tap Start and they begin: broken syllables, breaths, and pieces of English words, deep men and high women, forward and backwards, a few at a time with silence in between. Ask your question out loud, then listen. When a longer, clearer word or a whispered sentence comes through, the phone taps once and the screen flushes red. • Eight voice banks, each with its own tone, played in clusters with silence between • Echo, reverb, and a white noise bed that dips under the voices • Sweep rate from slow and sparse to fast and crowded • Every session is recorded with the effects you used and saved to the Library • Works offline, with no account and no ads, and it never uses the microphone Every sound is free to try for 48 hours. After the trial, a single one-time purchase unlocks Dead Channel for good. There is no subscription. Dead Channel is an instrument. It plays generated audio, and it does not prove the paranormal. Some voices are generated with Piper from the LibriTTS-R corpus (Koizumi et al., CC BY 4.0).
