OneTool: GPS, Compass, Level

OneTool is an all-in-one offline GPS and sensor toolkit with 6 instruments: digital compass, GPS speedometer, pedometer and step counter, barometric altimeter, bubble level and clinometer, and camera height meter (hypsometer). Use these tools for navigation, driving, walking, hiking, trekking, cycling, carpentry, DIY, surface leveling, angle measurement and height estimation. 🧭 DIGITAL COMPASS & QIBLA FINDER Find directions with a digital magnetic compass. • True North & Magnetic North: WMM magnetic declination correction. • Qibla Compass & Finder: Find the Kaaba direction and bearing for prayer. • Bearing Finder & Azimuth Lock: Lock a target bearing and track heading changes. • GPS Coordinates: View latitude and longitude in Decimal, DMS or UTM formats, plus address and local weather. • Magnetic Field / EMF Meter: Check magnetic field strength in microtesla (μT). • Night Vision Mode: Use a red-light theme in low light. 🚗 GPS SPEEDOMETER, CAR SPEEDOMETER & ODOMETER Use your phone as a car speedometer, bike speedometer and trip distance tracker. • Live Speed Tracker: View speed in km/h, mph, knots or m/s. • Trip Odometer & Logbook: Track distance, duration, maximum and average speed, and journey history. • Heads-Up Display (HUD): Mirror the speed display onto your windshield. • Speed Limit Alert: Visual, vibration and voice overspeed warnings. • Fuel Cost Calculator: Estimate trip fuel consumption and expenses. 👟 PEDOMETER, STEP COUNTER & WALKING TRACKER Track daily walking activity with a hardware step tracker. • Daily Step Counter: Count steps using your phone's step sensor. • Walking Distance, Time & Cadence: Track walking distance, duration and steps per minute (SPM). • Calories Burned Calculator: Estimate active calories. • GPS Stride Calibration: Calibrate step length for distance tracking. • Vehicle Motion Filter: Help reduce false steps during car or bus travel. • Step Goals & Streaks: View charts, history and personal records. ⛰️ BAROMETRIC ALTIMETER & ELEVATION FINDER Measure altitude and track vertical changes. • Sea-Level Elevation (MSL): View altitude using EGM96 geoid and WGS84 references. • Barometer & Pressure Meter: Read atmospheric pressure in hPa / mbar on devices with a pressure sensor. • Altitude Calibration: Use GPS, manual sea-level pressure (QNH) or a known elevation reference. • Ascent & Descent Tracker: Monitor elevation gain, descent, vertical speed and minimum/maximum altitude. 📐 BUBBLE LEVEL, SPIRIT LEVEL & CLINOMETER Level surfaces and measure tilt angles. • 2D Bullseye & Tubular Spirit Level: Check shelves, tables, picture frames, appliances and tripods. • Digital Clinometer & Inclinometer: Measure pitch, roll and vertical plumb angles. • Angle Finder & Slope Meter: Measure degrees (°), slope percentage (%) and roof pitch (in/ft). • Relative Zero & Hold: Set a reference angle or freeze readings. 🌲 CAMERA HEIGHT METER & HYPSOMETER Estimate the height and horizontal distance of tall objects. • Tree Height Meter: Sight the base and top of trees, poles and towers with the camera. • Building Height Calculator: Estimate building height and ground distance using eye-level height or a known baseline. WHY CHOOSE ONETOOL? • Six navigation and measurement tools in one utility app. • Offline tools for everyday use, travel, outdoor activities and DIY. • More measurement tools planned for future updates.
