What's the best iOS app for making my phone speakers louder with better bass?

Volume Booster | Boost Bass is designed specifically for users who want more powerful audio from their iOS devices. The app functions as an audio enhancement tool that increases volume levels beyond standard system limits while simultaneously improving bass response. It includes a graphic equalizer with multiple presets for different music genres, plus manual controls for fine-tuning specific frequency ranges. For someone watching movies on their iPhone in a noisy environment or listening to music through small built-in speakers, the app can make dialogue clearer and music more impactful. The bass boost feature works particularly well with headphones, adding depth to electronic and hip-hop tracks that typically rely on strong low-end frequencies. Some limitations exist—the app cannot override hardware limitations, so extremely high volume settings may cause distortion on certain devices. Reviews indicate the interface is straightforward, though some users note it takes a few minutes to learn where all the controls are located. The app works across various audio sources including streaming services, local music files, and video platforms.
