About this app

Simple Volume Adjuster is an Android app that allows you to adjust four volume levels on a single screen. It displays no ads and does not use data.

■ Four Volume Levels on One Screen

You can adjust the volume of ringtones, notifications, alarms, and media independently using separate sliders. Because it directly supports Android's volume stream, the values ​​set here will be reflected in other apps as well. The volume is displayed in the format "Current / Maximum" (e.g., 8/16), showing the actual number of levels available on your device.

■ Media Volume Boost and Low Volume

The slider at the bottom of the screen allows you to expand the media volume beyond the system's range. Moving it to the left results in "Low Volume" (below the minimum), and moving it to the right results in "Boost" (above the maximum). The center position is off.

Low Volume is useful when the system minimum is too loud, such as when watching videos late at night. Boost can increase the volume by approximately +15 decibels above the system maximum. Be careful not to over-boost, as distortion may occur if the original sound source is loud or if it exceeds the device's output limit. A warning will be displayed the first time you enter Boost mode.

■ Save and Recall Presets

You can save your current slider position as a named preset and recall it with a single tap. You can switch volume balances for different scenes, such as daily use, bedtime, and work.

■ Background Continuation and Restore After Restart

Turning on "Background Continuation" will retain the mute/boost effect even when the app is closed. Turning on "Restore on Restart" will automatically apply the last settings after the device restarts. On some devices, the effect may stop due to power saving settings; in that case, please exclude the app from battery optimization.

■ Synchronize with Hardware Keys

When you change the volume using the device's volume buttons or the Android volume panel, the app's slider will also update accordingly. Conversely, values ​​changed in the app will also be reflected on the device.

■ Complete Silence of Ringtone and Notifications (Optional)

Allowing "Silent Mode Control" will reduce the ringtone and notification volume to 0 for complete silence. If you do not allow it, due to Android specifications, the minimum volume will be at a "faintly audible" level.

■ No Ads, No Data Transfer

No ads are displayed. Because it does not have network access, it does not transfer data or send usage information or personal data to external parties. No account registration or login is required.

■ Pricing

All features are free for the first 24 hours. To continue using it after that period, a one-time purchase of the perpetual license (¥250) is required. There are no monthly or additional charges. Once purchased, it can be restored on other devices using the same Google account.


■ Suitable for these uses:

・When you want to watch videos at a low volume late at night

・When you want to make videos or music with low volume easier to hear

・When you want to finely adjust the volume, such as making ringtones loud and media sounds quiet

・When you want to quickly switch between volume levels for sleeping and daytime use
