LogLens is an offline-first flight log analysis app for drone operators and UAS engineers. Import PX4 ULog (.ulg) flight logs directly from the Files app, and get instant diagnostic analysis — no cloud, no accounts, no network required. What LogLens does: • Parses real PX4 ULog binary files on-device • Runs deterministic diagnostic rules for battery health, GPS quality, vibration, estimator status, and failsafe events • Displays a curated quicklook: health verdict, severity-coded findings with recommendations, event timeline, and charts (voltage, altitude, GPS satellites, flight modes) • Generates polished HTML and PDF flight reports you can share with your team • Stores everything locally — your logs never leave your device unless you explicitly export them Built for: • Drone operators and field test teams • Robotics and UAS engineers • Developers working with PX4 and open-source autopilot stacks • Anyone who wants fast situational awareness from a flight log Current format support: • PX4 ULog (.ulg) — fully supported • ArduPilot DataFlash (.bin) — sample data preview (full parser coming) • MAVLink Telemetry (.tlog) — sample data preview (full parser coming) Privacy is a feature: all processing happens on-device. No backend, no accounts, no tracking.
