SpectraWave Recorder
Read full descriptionHide full description
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.

GhostLab is a complete paranormal investigation toolkit for iPhone and iPad, built for night hunts. ONE HOME, SIX INSTRUMENTS MODES • EMF. DMP-style meter with green-to-red bars, recalibration, and radar view. • EVP. Clean microphone capture, plus presets for White Noise, Magnetic MEVP, Phonetic bursts, and DR60-style lo-fi. • Spirit Box. Rapid scan-style carrier mixed with your mic. • Spirit Speak. Ask aloud and watch experimental replies condense out of dead-channel static on the analog-footage screen, timestamped like recovered tape. ITC, not a conversation with the dead. • Spirit Music Box. Multi-sensor chime reacting to EMF, motion, and proximity anomalies. • SLS. ARKit stick-figure tracking that records the camera feed: figures and captions burned into the video, your microphone on the soundtrack. Recording survives locks and interruptions. Saving is instant. A12 or later. Pro, with a free trial. CREATOR MODE (PRO) Arm Creator, investigate in any mode, and a rolling 60-second screen plus mic buffer captures the moment. • Edit and Share. Export the last 60s into the in-app clip editor. • Trim, mute/volume, 9:16, 1:1, 16:9 crop, watermark, captions, speed, freeze, color grade, title cards, multi-highlight stitch. • Share to Facebook, Instagram, TikTok, YouTube, and more. • Clips attach to the session Library for later play, edit, and share. TOOLS FOR THE HUNT • Knock detector, Motion-Grid, Word Burst (Pro) • Estes Method workflow and Vigil overnight counters (Pro) • Team sessions. Offline push-to-talk radio and tag sharing (Pro) • Night Vis, torch, red-light UI, dBA level chips (approximate phone meters) • Verify instruments. Optional pre-session control checks LIBRARY AND EVIDENCE Stop and Save keeps audio, video, tags, notes, transcripts, and clips with each session. Review playback, edit clips, export PDF reports (Pro), and keep investigations organized by location, weather, and investigators. GHOSTLAB PRO Core recording stays free. GhostLab Pro is a one-time unlock, no subscription, for Creator Mode, Spirit Speak, SLS, advanced tools, voice packs, custom word lists, PDF reports, Enhance EVP, and more. Most Pro features include one free try. HONEST BY DESIGN GhostLab is for investigation and entertainment. Sensor tools measure the environment (phones, metal, HVAC, and movement all create hits). Dictionary and spirit-box style features are experimental ITC techniques, not scientific proof of spirits. Always review evidence yourself. Requires iOS 17 or later. SLS requires A12 or newer. Some tools need camera, microphone, motion, location, or local network permission. Guides, the full mode tour, and support: ghostlab.icu
