Flow Equalizer

Flow Equalizer is a free Android app for local audio tuning. It lets you shape sound across multiple frequency bands and includes advanced tools such as bass boost, treble gain, and frequency attenuation. Choose from preset sound profiles (for example, Rock, Classical, Jazz, and more) or fine-tune everything manually if you prefer a more hands-on approach.

The app can also store separate calibration settings for different audio devices—wired headphones, Bluetooth headphones, and speakers. When you connect a supported device, it can automatically load the matching profile, so you don’t have to switch settings every time.

All features are free, ad-free, and all sound processing happens on your device (locally), not on a remote server.
