HBB vs Toolbox Pro

HBB-K is an app designed for connecting to and locating items, making it easy for you to find lost belongings.

TURN YOUR IPHONE INTO A PRECISION TOOLBOX Toolbox Pro combines 23 measuring, detection, motion, environment, and outdoor instruments in one premium utility app. Check a shelf, inspect an angle, monitor vibration, read magnetic field strength, estimate sound level, find your heading, track speed, or measure with AR—without carrying separate devices. LEVEL, ANGLE, AND LENGTH • Spirit Level: horizontal and vertical bubble alignment, live tilt, and haptics near level • Inclinometer / Angle Meter: smooth degrees, reference reset, lock, and calibration • Protractor: circular angle gauge for quick surface checks • Plumb Bob: visual vertical alignment and deviation • Precision Ruler: full-screen centimeter and inch scales • AR Measure: estimate point-to-point length on supported devices • AR Height: estimate object or person height MAGNETIC FIELD AND METAL • Magnetic Field Meter: live X, Y, and Z axes, total microtesla, graph, average, and peak • Metal Detector: identify magnetic-field changes with threshold, sound, and haptics • EMF Meter: magnetic-field view with minimum, maximum, peak, and signal history The EMF feature uses the iPhone magnetometer. It measures magnetic field only and does not detect RF, 5G, Wi-Fi, cellular signals, microwave energy, or ionizing radiation. MOTION AND VIBRATION • Vibration Meter: live motion graph with RMS intensity and peak • G-Force Meter: X, Y, Z, total G, and maximum force • Accelerometer: raw three-axis acceleration • Gyroscope: three-axis rotation rate SOUND AND ENVIRONMENT • Sound Meter: approximate decibel reading, analog gauge, average, maximum, and calibration • Frequency Analyzer: dominant frequency with a live spectrum • Flashlight: torch, adjustable strobe, and SOS • Barometer: atmospheric pressure where supported • Altimeter: relative altitude where supported COMPASS, GPS, SPEED, AND DISTANCE • Compass: magnetic heading and true north when available • GPS Coordinates: latitude, longitude, accuracy, altitude, and course • Speedometer: GPS speed dial with km/h and mph • Distance Tracker: elapsed time and traveled distance SAVE AND REVIEW Keep readings in a private local history. Filter by instrument, review timestamps and min/max/average values, add notes, favorite records, and export supported data. Choose metric or imperial units. PRIVATE BY DESIGN No account, login, backend, or cloud is required. History and preferences stay locally on your iPhone. Sound analysis is processed live and is not saved as a recording or uploaded by Toolbox Pro. Location is requested only for tools that need it. Toolbox Pro checks hardware and permissions before measurement. If a sensor, AR capability, torch, microphone, motion service, or location service is unavailable, the app shows a clear unsupported state instead of failing. TRY IT, THEN UNLOCK PRO Use three complimentary tool sessions. Pro unlocks unlimited sessions and history, advanced graphs, peak/min/max analytics, calibration, custom thresholds and alerts, AR instruments, favorites, and CSV/PDF sharing where supported. Choose weekly, yearly, or lifetime access. Yearly includes a 3-day free trial for eligible customers, then renews at the displayed annual price unless canceled at least 24 hours before the period ends. Payment is charged to your Apple ID. Subscriptions renew automatically and can be managed in App Store settings. Restore Purchase is available in the app. IMPORTANT Toolbox Pro uses consumer iPhone sensors and provides practical estimates, not certified, medical, electrical-safety, occupational-safety, navigation, surveying, or legal measurements. Precision varies by iPhone model, case, calibration, environment, and interference. Use certified equipment whenever safety or compliance depends on the result.
