New: The compass shows an "Open settings" button when location access is blocked. Improved: The compass needle moves as smoothly as in version 1.1.7 again. Improved: Compass calibration now tells you when you did not turn the phone enough. Fixed: Strobe and SOS now stop when you switch flashlight mode. Fixed: Tapping "Enable microphone" twice no longer keeps the microphone on.
Sound level meter, dB & noise detector. Spirit level, bubble level, stud finder.
A decibel meter and sound level meter in your pocket, plus a spirit level, metal detector, compass, flashlight and 15+ sensor tools, all in one free app. Use it as a dB meter to check noise at home, at work or at a concert. The live display shows sound pressure level (SPL) in decibels with OSHA safety warnings, so this noise detector helps you see when a room is too loud. Use the bubble level as a simple level tool to hang pictures straight, and the metal detector as a stud finder app for walls. 🔧 PRACTICAL TOOLS • Spirit Level: 2D bubble level for hanging pictures, checking surfaces, and leveling furniture • Metal Detector: find studs in walls, locate pipes, and detect metallic objects with haptic feedback • Decibel Meter: measure sound levels (dB) with a live display and OSHA safety warnings • Vibration Analyzer: diagnose equipment issues and detect vibration patterns • Accelerometer: measure G-force, vehicle acceleration, and impact force 🧭 COMPASS & NAVIGATION • Digital compass with magnetic heading and cardinal directions • GPS coordinates (latitude, longitude, elevation) • Live altitude calculator using barometer + GPS • Tilt-compensated orientation for accurate readings • Magnetometer with strength display (µT) 📊 SENSOR DASHBOARD Monitor 10+ phone sensors live: • Accelerometer (X, Y, Z motion) • Gyroscope (rotation tracking) • Magnetometer (magnetic strength) • Barometer (atmospheric pressure) • GPS / Location • Proximity sensor • Ambient light sensor • Battery level and charging status • Sound level (decibels) • Pitch detector (frequency and musical note) 🔦 FLASHLIGHT & LIGHTING • Powerful LED flashlight with instant toggle • Strobe light (1 to 20 Hz adjustable) for parties and events • SOS morse code signal for emergencies • Red light mode to preserve night vision • Screen light with customizable colors • Auto-off timer (5, 10, 15, 30 minutes) 🎤 CONCERT MODE Stand out at concerts, festivals, and live events: • Scrolling text messages with emoji support • 10+ templates (MARRY ME, HAPPY BIRTHDAY, I LOVE MUSIC) • Beat-sync strobe: the flashlight pulses to music rhythm • Color effects: solid, gradient, rainbow animation • Share to TikTok, Instagram, and Snapchat 🎵 AUDIO ANALYSIS • Beat detection for music-reactive lighting • Pitch detection: identify musical notes (A4, C5, etc.) • Sound frequency analysis with FFT • Adjustable microphone sensitivity 💡 WHO IS THIS FOR? ✓ Home improvement: hang pictures straight, find studs, check surfaces ✓ Construction & DIY: level measurements, metal detection, vibration analysis ✓ Outdoor & hiking: compass navigation, altitude tracking, GPS coordinates ✓ Music & concerts: concert lighting, beat-sync strobe, sound measurement ✓ Students & teachers: physics demonstrations, sensor exploration ✓ Sound engineers: decibel monitoring, frequency analysis, pitch detection ✓ Emergency preparedness: SOS signal, flashlight, compass ⭐ WHY CHOOSE THIS APP? • 100% FREE: all tools included, no hidden paywalls • Works OFFLINE: most tools need no internet connection • LIGHTWEIGHT: small app size, low battery usage • PRIVACY-FIRST: all sensor data stays on your device • ONE APP replaces a sound meter, spirit level, metal detector, compass, flashlight, strobe light and a phone toolbox of sensor tools Whether you need a noise meter to check a loud room, a sound level meter for work, or a bubble level for a quick DIY job, it is all in one lightweight app.
