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.
