Bass Tester is a free Android app developed by Single Minded Productions LLC, categorized under Multimedia and Music & Radio subcategory. As the name suggests, Bass Tester generates a pure sine wave tone at the frequency it is set at, allowing you to test the bass frequency response of your sound system. The app includes some small samples of music designed to produce very low tones.

To use the app, you can hook it up to your subwoofer, car audio, or home system. However, if you listen to it on your phone, it won't sound like much. It is recommended to use a mini plug or Bluetooth and connect to your subwoofer to feel the bass.

Bass Tester allows you to feel the bass all the way down to 20 Hz and below, provided your sound system can handle it. With its simple interface and easy-to-use features, Bass Tester is a must-have app for anyone who loves to test their sound system's bass frequency response.
