🔧 12 TOOLS IN ONE
🔊 Sound meter (decibel meter)
Measure noise levels in decibels (dB) in real time, with minimum, average and maximum readings.

🔦 Flashlight
Steady light, strobe mode and SOS signal.
⏱️ Stopwatch and timer
Stopwatch with laps and a countdown timer with sound and vibration alerts.

✨ BUILT TO BE USED
• Home screen with one tool per row: open the one you need with a tap.

• 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.
