This app is developed to help users control volume without grabbing smartphones and side volume buttons.

[Volume Control in Status Bar]
Once you install this app, Volume controller will always be displayed on Notification bar. After that, you can easily control volume by scrolling down notification bar and clicking volume icons.

[Shortcuts]
I think this function is the highlight of this app as it was the motivation for me to develop this app. There are many decent apps to control volume, but they didn't provide shortcut functions. You can set two certain percentages of volume and use it in the controller on Notification Bar.

[Display Two or One Controller]
This app is focused on "Ringtone" and "Media" volume control. You can control other volumes such as "Voice call", "Alarm", and "System" volumes, but you can select "Ringtone" and "Media" volume controllers on Notification Bar.

[Mute / Unmute]
By simple click of icon in the controller on Notification Bar, you can easily kill sounds of your phone.

[Auto Start when rebooting]
Some user requested for this app to run automatically when rebooting phones, recently I added a function.

[Permission Control]
Certain Android O/S versions require "Do not disturb permission" for app to control "Ringtone Volume". If your android version requires this permission, an instruction page will pop up and guide you how to set the permission.

I hope this app can be useful for you ^^
