SPIRIT RADAR A live sweep reveals nearby entities, biased toward the real magnetic spikes happening around you. PENDULUM Hold your phone steady and ask yes or no questions. The accelerometer reads the tilt and answers Yes, No or Maybe. HUNT LOG Every investigation is saved automatically: location, duration, peak reading and every anomaly event.

SpectraWave is an EVP voice recorder that is honest about what it is. It records the real room through your microphone, then lets you replay each clip slowed down, reversed, and noise-reduced to pick out faint voices, all on your device. Nothing is uploaded, no voices are fabricated, and your captures are saved reliably so they never vanish. For entertainment purposes only. REAL MICROPHONE CAPTURE - Record the actual room with a live level meter - Every capture is saved reliably and survives relaunch - Works fully in airplane mode: nothing is ever streamed PLAYBACK THAT PICKS OUT VOICES - Slow any clip to half speed to hear syllables - Reverse it for classic backward-EVP review - A clarity filter lifts faint sound out of the hiss - All effects run on your device, on your real recording MARK AND EXPORT YOUR EVIDENCE - Tap to mark timestamped hits during recording or playback - Add a note to any marker and jump back to it later - Export the audio clip plus a marker transcript as CSV or text HONEST BY DESIGN - Real on-device capture and on-device effects, no server - No fabricated voices and no pre-recorded clips - No accounts, no tracking, no ads, no third-party SDKs FREE FOREVER - Record from the microphone and save your clips - Normal-speed playback of your library - One marker per clip SPECTRAWAVE PRO (one-time, no subscription) - Unlimited clips and recording length - The slow, reverse, and clarity playback effects - Unlimited markers with notes - Clip and marker-transcript export - The Action Button to start and stop without unlocking - A Live Activity recording timer on your Lock Screen and Dynamic Island - The Apple Watch remote to record, stop, and mark hands-free WHY SPECTRAWAVE - It just works. Real capture that always saves, the one thing every other recorder gets wrong. - Honest. On-device audio and effects mean nothing is streamed and no voices are faked. - No subscription. The core is free forever, and Pro is a single one-time purchase. - Yours, privately. Your audio stays on your device and only leaves if you share it. For entertainment purposes only. SpectraWave records real audio with your microphone and processes it with on-device effects. Results are not evidence of paranormal activity.
