Ghostalker is a unique paranormal investigation app designed to convert environmental energy into spoken words, functioning as a digital 'Spirit Box'. The app utilizes over a thousand commonly used words and employs all available sensors in your device - including vibration, rotation, GPS, gyroscope, light, magnetic fields, and proximity sensors - to detect subtle changes in energy and translate them into meaningful words. Ghostalker displays and vocalizes these words, providing users with an innovative tool for spirit communication.

This full version of the app offers advanced logging capabilities, allowing users to review, save, email, or delete spoken word logs at their convenience. Logs include date, time, sensor change readings, and corresponding words, formatted in CSV for easy import into spreadsheets like MS Excel or Google Sheets. Additionally, the app features a customizable dictionary function that lets users create personalized word lists of up to 10,000 entries, making it suitable for both professional paranormal investigators and casual users seeking interactive supernatural experiences.

Ghostalker distinguishes itself through its sophisticated sensor integration and comprehensive feature set. The app's primary innovation lies in its ability to utilize raw sensor data from mobile devices, converting minute environmental changes into spoken words rather than relying on random selection algorithms. This approach creates a more authentic and responsive paranormal investigation experience, particularly valuable during extended sessions where spirits might learn to interact with the device.

The application provides several professional-grade features, including individual sensor management (from v0.2), which allows users to enable or disable specific sensors to prevent interference issues. The custom dictionary functionality supports various investigation methods, enabling specialized word sets for different scenarios - from simple yes/no/maybe responses to complex alphabetical or numerical selections. The built-in calibration system helps manage background variance while maintaining optimal sensitivity, and the comprehensive logging system creates detailed records for later analysis, making Ghostalker particularly valuable for serious paranormal researchers.
