## What is Par?

Par-alarm is a simple monitoring alarm app that watches changes in volume or vibration in real time and alerts you when your selected threshold is reached.

Choose volume or vibration as the target, select “above” or “below,” and set your threshold. You can monitor the current value on a live graph and see how close it is to the alert condition.

Main Features:
・Real-time volume or vibration monitoring
・Alarm alerts based on your threshold
・Live graph showing the current value and threshold
・Countdown before monitoring starts
・Moving average filter for smoother readings
・Save setting presets
・Supports Japanese, English, Chinese, and Spanish

Use Par-alarm for checking noise levels, monitoring vibration changes, setting simple threshold-based alerts, or adding a fun trigger to party games.

Note:
This app does not guarantee safety. Please use it in a safe environment and take care to avoid dropping your device, falling, disturbing others, or creating safety risks. Use the app at your own responsibility.
