iPhone
Forensic sky observation. Identify satellites, stars and planets, detect motion anomalies, and preserve UAP evidence with SHA-256 integrity verification.
UAP Sentinel turns your iPhone into a specialized sky observation and forensic evidence capture tool. Identify satellites and celestial objects, monitor unusual motion, and preserve recordings with verifiable sensor data and cryptographic integrity checks.
Designed for UAP researchers, field observers, and dedicated skywatchers, UAP Sentinel combines orbital calculations, motion analysis, synchronized telemetry, and structured investigation dossiers.
CORE CAPABILITIES
◈ REAL-TIME SPOT & DEBUNK
Investigate bright objects before classifying them as unidentified. An integrated SGP4 orbital propagator calculates satellite positions using NORAD/TLE data. Identify 171 bright stars, planets from Mercury to Neptune, and the Moon, with detailed lunar phase, illumination, distance, and topocentric position data.
Orbital and celestial calculations work offline using available reference data.
◈ SENTRY MODE — AUTONOMOUS SKY MONITORING
Set up extended sky observation sessions with automatic motion analysis. Kinematic filters help flag unusual movement patterns for further investigation.
Adaptive frame rates (10–30 fps), thermal safeguards, and power management support extended recording sessions while balancing device performance and battery consumption.
◈ FORENSIC DOSSIERS & SHA-256 INTEGRITY
Capture HD video alongside synchronized sensor telemetry, including:
• CoreMotion orientation data (pitch, roll, yaw).
• Compass, GPS coordinates, and barometric altitude.
• Sensor telemetry logs exportable as CSV.
• Structured PDF investigation reports.
Add observer notes directly to investigation dossiers. Notes are automatically included in generated reports, submission templates, and exported archives.
A signed SHA-256 integrity ledger protects the integrity records of original video and telemetry files while tracking subsequent dossier revisions.
◈ TACTICAL OBSERVATION HUD
A specialized heads-up display provides real-time azimuth and elevation readings, vector indicators, and monochromatic display options designed for low-light observation.
PRIVACY-FIRST, ON-DEVICE PROCESSING
• Video, telemetry, and investigation data remain under your control.
• No proprietary cloud storage or third-party analytics.
• Observation and analysis tools can operate without continuous connectivity.
• Satellite catalog updates use public orbital data from CelesTrak.
UAP SENTINEL PRO
Unlock advanced investigation capabilities:
• Unrestricted Sentry Mode sessions.
• Unlimited forensic PDF reports and CSV exports.
• Automatic satellite catalog synchronization.
Choose a Monthly or Annual subscription, or a one-time Lifetime purchase. Annual subscription offers 40% savings.
UAP Sentinel is an observation and documentation tool. Motion alerts identify events for further analysis, not proof of extraordinary phenomena.

** UAP SENTINEL 1.5 — MAJOR UPDATES AND IMPROVEMENTS **
WHAT’S NEW
• Add observer notes to investigation dossiers, with updates automatically included in PDF reports, submission templates, and exported archives.
• New signed integrity ledger (SHA-256) for dossiers, protecting original video and telemetry files while tracking subsequent revisions.
• Expanded celestial identification with 171 bright stars, Mercury through Neptune, and enhanced Moon data including phase, illumination, distance, and topocentric position.
• New setting to control how many star markers are displayed.
IMPROVEMENTS
• Improved celestial marker accuracy and alignment.
• Enhanced accessibility across the entire app with Dynamic Type, VoiceOver support, adaptive layouts, and improved color contrast.
• Fully revised Italian localization, including onboarding, privacy, legal, subscription, recording, investigation, and settings content.
• More efficient camera, microphone, GPS, compass, and motion-sensor management for reduced battery and thermal impact.
• Improved recording, telemetry, and pre-roll coordination for more reliable evidence capture.
• Improved dossier integrity explanations and verification status reporting.
• Removed the diagnostic anomaly simulation control from Sentry mode.
• App updated to Swift 6 for improved safety, stability, and reliability during background operations.
BUG FIXES
• Fixed recording start/stop race conditions, including immediate finalization and background interruptions.
• Fixed pre-roll segments potentially being mixed between recording sessions.
• Fixed recording mode changes occurring while evidence capture was still active.
• Fixed stale sensor data being reused between sessions.
• Fixed invalid optical azimuth values near zenith or nadir; affected reports now correctly show the direction as indeterminate.
• Fixed Pro entitlement status not always refreshing correctly.
• Fixed satellite catalog recovery after partial responses or temporary server errors.
• Fixed thermal pause and pre-roll rotation edge cases.
• Fixed observer-notes keyboard handling and document regeneration.
• General stability, concurrency, performance, and localization fixes.
