Volume Booster - Loud Speaker

What it does

Volume Booster - Loud Speaker is an audio utility for people who want more control over how loud music, video, games or calls sound on their phone. It can raise volume for the phone speaker, headphones and Bluetooth audio, and offers quick level choices as well as a control for setting a specific level. You can also choose a music player to use with the booster.

A louder setting may not make audio clearer: at high levels, sound can become distorted, and loud listening can be uncomfortable or harmful. It is worth increasing volume gradually and checking whether the phone’s usual controls already meet your needs.

Who might find it useful

This may suit someone whose audio seems too quiet through a particular output, or who wants volume controls close at hand. A small home-screen widget is described as an option for quick access. If you rarely struggle to hear audio, another control on your phone may be all you need.

Who makes it

The developer is Coocent. The listing shows a rating of 4.55 out of 5 from 80,373 ratings and more than 10,000,000 installs. Those figures indicate that many people have tried the app, but they do not tell you whether it will work well with your phone, headphones or preferred audio player.

Before you decide

Consider what you want the booster to do and whether you would use it often enough to keep it. Since the supplied details do not spell out the app’s access requirements, check the permissions shown on your device and ask whether each one makes sense for a volume tool. If it does not solve a real listening problem, you can leave it off your phone; if you try it and later stop using it, remove it rather than keeping an app you no longer chose.
