Flat Equalizer FX-Bass Booster is a simple on-device tool that lets you connect to Bluetooth speakers, play music, and fine-tune your sound.

Key features include quick Bluetooth connectivity, direct playback from supported devices, and versatile tone generation for setup and testing. All functions run on your device with no extra accounts. Subscriptions with auto-renewal are available; manage them in your device's account settings.
