Threshold vs SpiritTrace

Threshold: Spirit Box Lab is a focused paranormal investigation app that generates indexed word outputs from live magnetic-field and device-motion activity. Instead of releasing words through a simple repeating timer, Spirit Box Lab uses calibrated sensor activity, sensitivity-based triggering, cooldown behavior, and deterministic indexed selection from a carefully curated 2,048-entry production vocabulary. Configure a Session, Area, sensitivity level, and spoken-output preference before beginning a run. Generated outputs, timestamps, and available technical Trigger Details are saved for later review. SPIRIT BOX LAB • Generate indexed word outputs from live sensor activity • Choose Low, Medium, or High sensitivity • Enable or disable spoken output • View fused magnetic-field and motion activity • Follow trigger progress and cooldown status • Review recent outputs during an active run • Save completed and interrupted runs automatically • Organize runs by Session and Area TRIGGER DETAILS Review the technical context behind saved outputs, including available information such as: • Accumulator activity • Magnetometer contribution • Device-motion contribution • Cooldown state • Sensor-derived signature • Word Index Trigger Details help preserve the conditions surrounding each generated output for later comparison and interpretation. MAGNETIC FIELD MONITOR Monitor live magnetic-field strength and changes from a calibrated baseline. View: • Current magnetic-field magnitude • X, Y, and Z axis readings • Change from baseline • Peak activity • Responsive activity levels Nearby magnets, speakers, electronics, charging equipment, metal objects, and changes in phone orientation can affect readings. VIBRATION BEACON Use the iPhone’s motion sensors to monitor device movement and surface vibration. Choose a sensitivity level and observe: • Current movement level • Stable, movement, and strong-movement states • Movement event count • A responsive full-screen visual beacon For more stable comparisons, place the phone on a fixed surface and avoid unnecessary handling. SESSIONS AND AREAS Create Sessions for separate investigations and Areas for individual rooms, zones, or locations. Saved Spirit Box runs remain connected to the selected Session and Area so activity can be reviewed within its original investigation context. Runs may also be saved as Unassigned when no Area is available. FREE ACCESS Free access includes: • 15 total minutes of complimentary Spirit Box monitoring • Up to 5 minutes per individual run • Calibration time excluded from complimentary usage • Access to previously saved runs after complimentary time is used • Magnetic Field Monitor • Vibration Beacon SPIRIT BOX LAB PRO Upgrade once for lifetime access to: • Unlimited Spirit Box monitoring • Unlimited saved Spirit Box runs • More Sessions and Areas • Trigger Details Spirit Box Lab Pro is a one-time in-app purchase. No subscription is required. PRIVACY-FOCUSED Threshold: Spirit Box Lab does not require an account. Core investigation data is stored locally on your device, and you control what you review or share. Sensor readings and generated outputs should be interpreted within the full context of the investigation. Designed for iPhone.

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. The monthly plan has no trial. Your localized price and terms appear before purchase. Subscriptions renew automatically unless canceled at least 24 hours before renewal.
