## What is UAP Sentinel?

In the study of unidentified anomalous phenomena (UAP), separating background clutter from authentic anomalies demands scientific rigor and verifiable data. UAP Sentinel turns your iOS device into an aerospace-grade tactical observation and forensic capture workstation.
Engineered for field researchers, aerospace observers, and serious skywatchers, UAP Sentinel combines high-frequency sensor telemetry, autonomous orbital mechanics, and cryptographic chain-of-custody verification—processing everything on-device, with no proprietary servers.

CORE CAPABILITIES:
◈ REAL-TIME "SPOT & DEBUNK"
Eliminate false positives on the spot. An integrated, fully offline SGP4 orbital propagator predicts artificial satellite passes (NORAD/TLE catalog) and the positions of celestial bodies (Key navigational stars). Point at any bright light source to identify or rule out conventional targets without network connectivity.

◈ SENTRY MODE (AUTONOMOUS SKY MONITORING)
Deploy your device for extended observation sessions. Dynamic thermal and battery power management balances frame rates (10fps to 30fps), while kinetic motion filters scan the sky for non-ballistic flight characteristics: extreme high-G maneuvers, instantaneous turns, and severe velocity jerk.

◈ FORENSIC DOSSIER & SHA-256 CHAIN OF CUSTODY
Capture research-grade evidence ready for technical review. Record high-definition video synchronized frame-by-frame with 30Hz sensor telemetry:
• High-frequency CoreMotion attitude (pitch, roll, yaw).
• Calibrated gyroscopic compass, GPS coordinates, and barometric altitude.
• Raw telemetry logs exported in standard CSV format for laboratory analysis.
• Tamper-evident forensic PDF report stamped with an SHA-256 cryptographic hash via Apple CryptoKit, establishing an unalterable chain of custody.

◈ MIL-SPEC TACTICAL HUD
Vector heads-up display engineered for low-light observation. Real-time azimuth/elevation readouts and night-vision-preserving monochromatic palettes prevent pupil dilation loss in dark environments.

100% ON-DEVICE, NO PROPRIETARY SERVERS
• Zero cloud uploads, zero telemetry collection, zero third-party analytics.
• Full functionality in deep wilderness, offshore waters, and remote field camps — the only network request is the public orbital data download from CelesTrak for the Pro satellite sync.
• Complete custody and ownership of your raw video and telemetry logs.

UAP SENTINEL PRO
Unlock full tactical capabilities:
• Unrestricted Sentry Mode monitoring sessions.
• Unlimited SHA-256 cryptographic PDF reports and CSV telemetry exports.
• Automatic TLE satellite catalogue sync from CelesTrak.

## Version history (last 4 releases)

### 1.4 — 2026-10-01

What's new in version 1.4

• Pro: the satellite catalogue now updates on its own, no need to tap the TLE badge.
• More accurate sky: the reticle is aligned with the camera and markers sit on the real stars, even near the edge and when zoomed.
• Without GPS the app no longer "explains" objects from a wrong position: the status panel shows "No GPS Fix" and reports say NO GPS FIX.
• Satellites: more reliable identification, unknown satellites are no longer labelled as ISS, and orbital data is validated.
• Sentry: pre-roll always preserved, "Camera interrupted" notice with automatic resume, and tripod movement is detected even without location access.
• Dossiers: describe the trigger moment and every object seen, the PDF flows onto multiple pages, and they take about half the storage.
• Camera and microphone turn off in the Investigation and Settings tabs.
• Permissions are requested only during setup, clearer subscription and Restore Purchases feedback, VoiceOver improvements.

### 1.3 — 2026-09-29

New Features:
   • New Disclaimer with the terms of use, available in Settings → Legal.
   • Free users can now export the original video of every investigation.

Bug Fixes:
   • Saving evidence no longer freezes the app, even with long recordings.
   • If you leave the app during a recording, the video is closed and saved automatically to the archive.

### 1.2 — 2026-09-27

Sentry Mode Enhancements: Improved monitoring responsiveness and fixed an issue that could prevent it from engaging properly during background tracking.
Other correct issues:
   • Collected evidence is now stored permanently and included in iPhone backups; dossiers from previous versions are moved automatically.
   • The archive only marks as ready and exportable the files that are actually present.
   • Reticle: star, planet and satellite markers now stay aligned with the sky even when the phone is tilted.
   • Pro subscription status now updates instantly after purchases, restores and renewals.
   • The paywall only offers a free trial when your account is eligible, and shows price and renewal period.
   • Sentry mode: the screen no longer auto-locks during surveillance.
   • Interrupted recordings always keep the real footage

### 1.0 — 2026-09-21
