Sensors Toolbox vs LogLens

Sensor toolbox makes the most of all the sensors in your smartphone. With a user-friendly interface and easy to read layout, Sensor Multitool - Toolbox allows you to collect data in real time for any and all sensors on your phone. Convert the data into easy to read graphs with a detailed readout from each sensor. This app contains everything you need: an accelerometer, gyroscope, GPS Data, barometer, decibel meter, metal detector, compass, and much more. This app follows all material design guidelines, meaning the app is clean and simple to use This app uses intuitive graphs to create clean, orderly graphs of all data collected.

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.
