霊探知機

霊探知機は、スマートフォンに搭載された複数のセンサーを使って「見えない何か」の気配を探知する、エンターテインメントアプリです。 ■ マルチセンサー探知エンジン 磁気・加速度・気圧・環境音の4チャンネルを常時解析。複数のセンサーが同時に異常を検知した瞬間、針が振れ、本体が振動します。ガイガーカウンターのように、反応が強いほど振動は激しくなります。 ■ 場所に反応する 一度強い反応があった場所に近づくと、探知機は再び反応しやすくなります。また全国の「いわくつき」エリアのデータベースを内蔵。「この付近に何かある…」の表示が出たら、そこは要注意です。 ■ ハイスコアと全国ランキング 会員登録(無料)すると、探知した最大ボルテージを記録できます。記録は停止操作なしでリアルタイムに保存。自己ベストTOP3は記録エリア・日時とともにホーム画面に表示され、全国ランキングで日本中の探知者と競えます。 ■ プライバシーへの配慮 ・記録される位置は約600m四方のエリアに丸められ、正確な地点は特定できません ・マイクは騒音レベル(dB)の解析のみ。録音・保存は一切行いません ・位置情報・マイクは探知中のみ使用します ■ ご注意 本アプリの探知結果は、端末センサーの変動に基づく演出です。心霊現象・超常現象の存在を科学的に証明するものではありません。

A logbook for places that feel wrong. Walk into a room that gives you that feeling. Tap once. Hold still for two seconds while the rig baselines. GhostTrail starts reading your phone's magnetometer, accelerometer, and GPS — for up to sixty seconds, or until you tap stop. You get a pin you can keep on your phone, or share to the World Map so other spotters can see what your phone measured. WHAT IT IS • An honest sensor recorder. The readings are what the phone measured. Nothing else. • A logbook with retro VHS chrome. Each capture earns a tape number, a phosphor-green status readout, and — for curated landmarks — a multi-section lore card you can export as an Instagram Story sticker. • A curated map of nearly 200 places across six continents — locations known for the kind of stories that make people lower their voice. WHAT IT IS NOT • A ghost detector. The app never interprets readings. It logs them. • A microphone recorder. The permission is never requested. • A tracking app. No advertising identifiers. No analytics. No third-party trackers. SIGNALS — THE PEEK ECONOMY Opening another spotter's public pin costs one Signal. You start with three free Signals, and every pin you publish yourself earns one back — no daily caps, no limits. Out of Signals? Publish your own pins, or buy a Signal pack from Profile → SIGNALS. Three pack sizes: 3, 12 (+25% bonus), or 30 (+40% bonus). PRIVACY BY DEFAULT • Captures stay on your phone by default. Nothing leaves the device until you tap SHARE TO WORLD MAP. • Shared coordinates are fuzzed by ±30 meters before upload. Precise location never leaves the device. • Sign in with Apple is the only auth method. Apple's private email relay is supported. • Profile → Delete account permanently removes everything you have shared. FOUR TIERS OF ANOMALY Quiet · Stir · Pulse · Surge. The same readings, four amplifications of chrome. Your screen reacts to what the rig is seeing. A haptic pulse fires on every tier crossing. No sound is ever played. DESIGNED FOR LATE-NIGHT USE Phosphor green on near-black. Retro VHS scanlines. Monospace timecode. The interface stays out of the way. REQUIREMENTS • iPhone running iOS 17 or later • Magnetometer (every modern iPhone has one) • Location and motion permissions, granted on first capture • Camera permission optional — only for photos attached to pins • Photo Library Add permission optional — only when saving an Instagram-bound landmark sticker GhostTrail does not detect ghosts. It logs environmental sensor readings as data, not as paranormal claims.

Verdict
The clearest difference is in-app purchases: 霊探知機 at none against GhostTrail's 3. 霊探知機 also leads on device support (3 vs 1) and iOS requirement (15.0 vs 17.0). GhostTrail's advantage is ads (none vs shown) and update cadence (monthly vs every 4 months). On price there is nothing between them.
