SPIRIT TRACE — GHOST HUNTING, REIMAGINED. Looking for a different kind of paranormal investigation experience? Spirit Trace is a ghost-hunting and EVP-style investigation tool with a unique feature: Trace Field builds visual formations from potential responses and connections throughout your investigation. Don’t just detect a strange word or sound. Follow the trail. Look for repetitions. Explore how potential responses appear across a session. THE DIFFERENCE: TRACE FIELD Most paranormal investigations involve listening, asking questions and trying to remember what happened. Spirit Trace gives you another way to examine a session. Ask a question. Listen for a potential response. Notice when words or speech fragments appear again. Trace Field brings potential connections together in a visual formation, helping you explore patterns across your investigation rather than treating every moment as an isolated event. It’s a different approach to ghost hunting, built around the question: WHAT HAPPENS WHEN A RESPONSE APPEARS AGAIN? ASK. LISTEN. TRACE. • Ask investigation questions by voice or text. • Listen during dedicated response windows. • Review potential speech fragments and repeated words. • Follow your session through an investigation timeline. • Explore emerging patterns and connections in Trace Field. • Record and revisit previous investigations. BLIND MODE — INVESTIGATE WITHOUT THE EXPECTATION Want to reduce the influence of what you expect to hear? Blind Mode lets you investigate without seeing certain detected information as it happens. Review your session afterwards and compare your experience with what was recorded. SKEPTIC MODE — QUESTION WHAT YOU FIND Not every unusual sound has a paranormal explanation. Skeptic Mode encourages a more critical approach to potential responses, helping you question, compare and review rather than immediately accepting a result. BUILT FOR PARANORMAL INVESTIGATIONS Whether you investigate at home, explore reportedly haunted locations, conduct EVP sessions or simply enjoy exploring the unexplained, Spirit Trace gives you a structured way to ask questions, listen carefully and review what happens. Use it during a session, then revisit the timeline to look for details you may have missed in real time. WHY SPIRIT TRACE? A single strange sound can catch your attention. A word that appears again can make you look closer. A sequence that seems connected to your questions can make you want to review the whole session. Spirit Trace is built around exploring those moments and examining the possible connections between them. DON’T JUST COLLECT STRANGE MOMENTS. TRACE THEM. IMPORTANT INFORMATION Spirit Trace is an experimental paranormal investigation tool. It does not scientifically prove the existence of ghosts, spirits, communication with the dead or paranormal activity. Potential words, speech fragments and apparent patterns can have ordinary explanations, including background noise, interference, environmental sounds, expectation and human interpretation. Treat results as possibilities to investigate, not verified paranormal evidence. Start an investigation. Ask questions. Listen carefully. See what patterns you notice. SPIRIT TRACE — DON’T JUST DETECT. TRACE THE CONNECTION.
