Automatic Volume Adjustment Based on Speed
Automatic Volume Adjustment based on the detected movement speed using GPS. This app is recommended for those who listen to music while driving by connecting their Android device to a car audio system. It automatically lowers the volume when waiting at a traffic light or driving through a residential area at a slow speed, and increases the volume when accelerating, allowing you to listen to music without disturbing others even with the windows open.
In addition to driving, this app can also be used while jogging, on a train, bicycle, or motorcycle, where the volume can be increased to match the wind noise or surrounding noise as you accelerate.
Although this app does not have a built-in music playback function, it can easily be used in conjunction with other music players as it operates in the background.
Some models also have the additional feature of turning the FM transmitter on/off (possibly only available on IS01, IS03, IS05. Confirmed on IS03).
――How to Use――
This app offers two adjustment modes: "Two-Step Mode" and "Multi-Step Mode".
In "Two-Step Mode", you can set a reference speed and adjust the volume when the speed is below or above that reference speed. Once you have set the volumes, simply press the ON/OFF button at the bottom to start the automatic volume adjustment.
In "Multi-Step Mode", you can set volume levels for pre-determined speed ranges such as [10-20km/h]. Press the ON/OFF button at the bottom to start the automatic volume adjustment.
To stop either mode, press the ON/OFF button again or select "Exit" from the device's menu button. You can also make changes to the settings while the app is running, so feel free to adjust as needed.
