The lights flicker. Your phone hums in your hand. Somewhere in the static, a voice is trying to come through. Are you listening? Ghost Hunting Tools is a full paranormal investigation kit running on your phone. Spirit box, EVP scanner, ghost detector, and EMF meter, all in one app. Built for first-time ghost hunters and veteran investigators alike. Free to use, with a Pro upgrade when you are ready to dig deeper. What's inside Spirit Box and Ghost Talker Open a session and the app scans for ghostly signals, pulling words from a curated dictionary in real time. Read them on screen, hear them spoken aloud, and watch as patterns start to form. The kind of one-word-at-a-time communication serious investigators look for, without the radio hiss. EVP Scanner Capture Electronic Voice Phenomena from the ambient noise around you. Phrases, fragments, names. Some you will write off as coincidence. Others will sit with you longer than you expected. EMF Detector (NEW on iOS) Brand new in version 2.21.4: a working EMF meter pulled straight from your phone's sensors. Watch the readings spike when something steps into the field. Cross-reference with the spirit box and you have two channels lining up at once. Sensor Dashboard EMF, motion, light. Your phone has more paranormal-detection capability than most people realize, and the dashboard reads all of it. Easy-to-follow graphs let you spot the moment everything goes quiet, right before it doesn't. The Word Bank A large dictionary of words the app surfaces during scans. No filler, no random noise for the sake of it. Just the vocabulary that paranormal investigators have reported reaching for them again and again. Pro unlocks a much bigger bank and lets you add your own words. Pro Version Remove ads, unlock the expanded dictionary, and add custom words of your own: names of the deceased, places of interest, anything you suspect might be listening. Pro purchases also fund continued development of the app, so the hunt keeps getting better because of the people who go pro. Why people keep this app on their home screen You do not have to believe in ghosts to enjoy Ghost Hunting Tools. You just have to be curious about what happens in the quiet moments. Open the app at a bonfire, in a basement, in an empty hotel room. Bring a friend. Tell us what you find. Ghost hunt safely Trust your instincts. Don't go alone to places you don't know. If something feels wrong, close the app and walk away. Tools are tools, and your judgment is what keeps you safe. A note on entertainment Ghost Hunting Tools is built for fun and curiosity. We can't promise you will talk to a real ghost. We can promise you will have a story.

Spirit Phone Innovations (SPI) — Experimental ITC Research Software Spirit Phone Innovations (SPI) is an experimental paranormal research application developed to explore new approaches to Instrumental Trans-Communication (ITC). Conceptualized by paranormal researcher Sean Austin, SPI is designed to analyze environmental audio using artificial intelligence in a way that differs from traditional ITC-style applications. At the core of SPI is SAM Mode, an experimental feature that analyzes environmental audio in real time and applies AI-based processing to identify and interpret audio patterns that may exist outside of normal human speech ranges. Unlike applications that rely on fixed word banks or pre-selected vocabulary, SPI is designed without predetermined phrase limitations, allowing for open-ended analysis rather than scripted responses. KEY FEATURES SAM Mode Audio Analysis: Experimental AI-driven analysis of environmental audio for potential anomalous patterns. No Word Bank Limitation: Designed without a fixed vocabulary list, allowing results to remain unrestricted by preset phrases. Session Logging & Word History: Detected words and session results are automatically saved to an in-app log folder, allowing users to review, compare, and document findings over time. Language Interpretation (Experimental): Optional translation of detected words when foreign-language patterns are identified. Estimated Voice Characteristics: Experimental analysis providing estimated age range and gender characteristics based on detected audio patterns. Community Activity Mapping & GPS Directions: Users can place location pins to document reported activity, view shared locations from other users, and receive GPS directions to reported sites. SPI was designed with the idea that ITC research benefits from documentation, pattern comparison, and shared exploration. The goal is not to provide predetermined answers, but to create an environment where users can explore potential patterns in audio and compare results across locations, environments, and sessions. SPI is intended for exploration and research. Results are not guaranteed and may vary. Spirit Phone Innovations is an evolving platform committed to continuously expanding and refining its tools as AI technology advances. SUBSCRIPTION INFORMATION SPI requires a subscription to access its features. Two auto-renewable subscription tiers are available — Standard and Ghost — each offered as monthly or yearly plans. Standard includes: EVP detection, frequency range control, and paranormal hotspot reporting. Ghost includes: Everything in Standard, plus age and gender detection and multi-language EVP translation. Payment will be charged to your Apple ID account at confirmation of purchase. Subscriptions automatically renew unless canceled at least 24 hours before the end of the current period. Your account will be charged for renewal within 24 hours prior to the end of the current period. You can manage and cancel your subscriptions at any time through your App Store account settings.

Verdict

The call

The clearest difference is rating: Ghost Hunting Tools at 4.2 against SPI's 3.4. Ghost Hunting Tools also leads on ratings volume (9.5K vs 127) and review sentiment (67% vs 58%). SPI's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, update cadence, in-app purchases and device support there is nothing between them.
