About this app

Are you disturbed by loud neighbors, construction noise, or wondering if your bedroom is quiet enough for deep sleep? Transform your smartphone into a professional-grade Sound Meter & Noise Tracker. This app is not just a live decibel (dB) meter; it is an advanced noise logger designed to measure environmental sounds, save your history as evidence, and analyze your daily sleep environment.

Whether you want to protect your hearing, record noise pollution, or find the perfect quiet space, this app provides accurate real-time data from 0 to 160 dB with a stunning, easy-to-read interface.

🌟 CORE FEATURES:

📊 Real-Time Decibel Meter (dB)

Accurately measure environmental noise levels in real-time.

Wide measurement range from 0 to 160 dB (enhanced with software boost for loud environments).

Live audio waveform chart and circular gauge for instant visual feedback.

Displays Minimum (MIN), Average (AVG), and Maximum (MAX) decibel levels during your session.

📅 Noise History & Evidence Logger

Unlike basic sound meters, our app saves your measurements!

Built-in Calendar: Tap on any date to review your past noise logs.

Track the exact time, duration, Max/Avg dB, and noise type for every session.

Perfect for gathering evidence of loud neighbors, noisy workplaces, or tracking noise pollution over time.

🛌 Sleep Environment Analyzer

Is your room too loud for a good night's rest?

Our smart "Sleep Environment Meter" automatically analyzes the current decibel level and tells you if your room is "Optimal," "Caution," or "Unsuitable" for deep sleep.

📖 16 Real-World Noise References

Understand what the numbers mean! The app instantly compares your current dB level to 16 real-world examples (e.g., Whisper, Normal Conversation, Heavy Traffic, Factory, Concert, or Rocket Launch).

⚙️ Advanced Customization & Privacy

Microphone Calibration: Adjust the sensitivity (+/- 20 dB) to match professional SPL meters.

Dark Mode & Light Mode: Beautiful UI optimized for day and night use.

100% Privacy Focused: All audio processing happens on your device. We DO NOT send, record, or save your voice to any cloud server. Your data stays securely in your local storage.

Global Support: Fully localized in 16 languages including English, Spanish, Japanese, Arabic (RTL support), and more!

Perfect for:

Checking noise levels in apartments before moving in.

Logging evidence of noise complaints.

Testing the acoustic environment of your baby's room.

Protecting your hearing at concerts or factories.

(Note: Hardware microphones in most mobile devices are tuned to human voice frequencies. Extreme loud sounds over 90-100 dB may be limited by your device's hardware AGC. Our software boost helps, but for industrial precision, a dedicated SPL meter is recommended.)
