From leveling a shelf to measuring a photo or planning your next project, Toolbox brings useful measuring instruments, calculators and everyday utilities together in one place.
Find the tool you need with search, organize your favorites and return quickly to recently used tools.
Measure angles and check levels
Check inclination, slope and surface level. Use a protractor, follow a plumb line or place reference lines over your camera view with Laser Level. Explore tools for corner rotation, rotation angles, vehicle pitch and roll, and roof pitch.
Measure objects, photos and maps
Use the screen ruler for length, area, diameter, thread pitch and wrench size. Add measurements and annotations to photos with Image Meter, or measure distances and areas on a map.
Find directions and plan alignment
Check your heading with the compass, save places and explore the map. Find tools for solar panel and satellite dish alignment, plus strike and dip measurements for rock layers.
Explore light, sound and motion
Check light levels, estimate noise levels, explore magnetic fields and monitor vibration. Measure height differences using a supported barometer, estimate rotational speed with the tachometer and inspect the sensors available on your phone.
Analyze sound frequencies with the audio spectrum and spectrogram, or generate tones, sweeps and pink noise.
Work with colors and camera views
Pick color names and codes from the camera or a photo. Explore color vision simulations and highlight a selected color.
Calculate and organize
Convert units and work through construction, electrical and pipe bending calculations. Keep tasks with reminders and attachments, run multiple project timers, set work and rest intervals, and track laps with the stopwatch.
Make Toolbox your own
Choose list or grid browsing, personalize your home layout and switch between light and dark themes. Keep saved records, photos and charts within reach, with built-in Help for supported tools.
Some tools, features and layouts require Plus or Pro access. Optional rewarded ads provide temporary upgrades.
Tool availability and measurement accuracy depend on your device’s hardware, sensors and calibration.
Toolbox is not a medical device. Its tools cannot diagnose an illness or be used to treat, cure or prevent one. Sleep and sound features give general information using your phone’s microphone and automated recognition, so results may be wrong. Get advice about symptoms, diagnosis or treatment from a qualified healthcare professional.
Level, measure, calculate and explore with practical tools in one app.
