🔧 12 TOOLS IN ONE

🔊 Sound meter (decibel meter)

Measure noise levels in decibels (dB) in real time, with minimum, average and maximum readings.

⚖️ Bubble level

Check whether a surface is flat, with circular and tube levels. You can calibrate it.

📐 Inclinometer

Measure angle and slope as a percentage. Hold the reading and zero it wherever you need.

📏 Ruler

Measure objects in centimeters and inches, with calibration for better accuracy.

🔍 Magnifier

Use your camera as a magnifying glass with zoom to read small print. Freeze the image and turn on the light.

🧭 Compass

Check your magnetic heading instantly.

☀️ Light meter (lux meter)

Measure ambient light in lux and see the minimum, average and maximum. Requires a light sensor.

📍 GPS speedometer

Shows speed, altitude, heading, accuracy and distance traveled, plus top speed.

🔦 Flashlight

Steady light, strobe mode and SOS signal.

⏱️ Stopwatch and timer

Stopwatch with laps and a countdown timer with sound and vibration alerts.

🔄 Unit converter

Length, weight, temperature, volume, area, speed and time.

➕ Counter

Keep several tallies at once, with names, saved on your device.

✨ BUILT TO BE USED

• Home screen with one tool per row: open the one you need with a tap.

• Mark your favorites with the star and they stay at the top.

• The screen stays on while you measure.

🔒 PRIVACY AND ADS

• Free with ads. A one-time purchase removes them for good, with no subscription.

• The tools calculate everything on your device and work offline (ads need an internet connection).

• It doesn't record audio, save photos or store your location.

• Permissions (microphone, camera and location) are requested only when you open the tool that uses them, and you can deny them: the rest of the app keeps working.

📱 NOTES

• Some tools depend on your phone's sensors (accelerometer, magnetometer, light sensor, GPS, flash). If your device lacks one, that tool will tell you and the others stay available.

• Results are approximate and do not replace calibrated professional instruments. Accuracy depends on each device's hardware.
