Compass Level & Sound Meter

An all-in-one sensor toolbox: compass, spirit level, sound meter, metal detector, GPS speedometer, ruler, unit converter, magnifier, altimeter, barometer, light meter and more — 15 precision instruments in one utility app. Every sensor tool works offline, without internet or Wi-Fi, and there is no sign-up. One smart toolbox instead of a dozen single-tool downloads. 🧭 COMPASS Smart digital compass with heading, pitch and roll. True north, azimuth and live calibration for pinpoint direction finding — perfect for hiking, navigation and outdoor adventures. 📐 SPIRIT LEVEL Bubble level for horizontal and vertical surfaces. Check shelves, frames, tables and DIY projects with precision — a precise bubble level, inclinometer and protractor in your pocket, with angle readout in degrees. 🔊 SOUND METER (dB) Real-time decibel meter with session average, peak and noise-safety zones. A professional sound level meter to track noise around you and protect your hearing. 🔍 METAL DETECTOR Magnetic field detector and stud finder with a live magnetic intensity graph. Find hidden metal objects, stud-sniff behind walls, and verify magnetometer readings in µT. 🚗 GPS SPEEDOMETER Digital GPS speedometer and odometer. Track current, average and max speed, plus total distance travelled — great for driving, cycling, running or e-scooters. 👣 PEDOMETER Step counter with distance, calories and active time. Set daily goals and see your walking pace outlook at a glance. 🔦 FLASHLIGHT More than a torch. Bright LED flashlight, SOS emergency signal, strobe mode with adjustable speed, and soft screen light for ambient illumination. 🔎 MAGNIFIER Camera-based digital magnifier with zoom, freeze frame and flashlight — read fine print, labels and tiny electronics without strain. ⛰️ ALTIMETER GPS altimeter shows elevation above sea level — useful for trekking, cycling, flights and weather tracking. 🌡️ BAROMETER Live atmospheric pressure sensor in hPa with trend history — a practical weather tool for outdoor planning. 💡 LIGHT METER (LUX) Ambient light sensor reading in lux — ideal for photography, study desks, plant care and workspace setup. 📳 VIBRATION METER Accelerometer vibration analysis with live graph — handy for DIY, auto diagnostics and earthquake curiosity. 📏 RULER On-screen ruler in millimetres and inches, with a numbered scale that starts right at the edge of the screen. Tap to mark a point, and drag to scroll the scale for anything longer than the screen. 🔄 UNIT CONVERTER Length, weight, speed, area, volume, pressure and temperature. Exact fixed factors, so it works fully offline and never goes stale. 🌡️ THERMOMETER Ambient temperature from your phone's built-in temperature sensor, in °C or °F. Only a few phones ship this sensor — if yours doesn't, the app says so rather than showing a battery reading dressed up as room temperature. ✨ WHY THIS TOOLBOX? ✔ 15 professional tools in one all-in-one toolbox ✔ Clean, modern Material You interface — no learning curve ✔ Real-time readings with live graphs, peaks and history ✔ Calibration support for compass, level, metal and vibration ✔ Works 100% offline — no internet needed ✔ Lightweight, battery-friendly, zero clutter ✔ No sign-up and no account — open it and start measuring Whether you're a DIY enthusiast, outdoor adventurer, student, engineer or just someone who loves a good utility app — this toolbox gives you the right instrument for every situation.
