EQfy FAQ: Volume Booster & Equalizer Help

EQfy - Louder Volume is an iPhone app that makes the music you play in it louder and fuller. It combines Volume Boost up to 200%, Bass Boost, a 7-band equalizer, headphone balance, 3D Audio and an AI Studio with a free music library and player that also works offline. See all features.

Yes. EQfy is free to download, and Volume Boost and the music library and player are free to use. Bass Boost, the equalizer, headphone balance, 3D Audio, playback speed, the haptic player and export are part of the optional Premium subscription.

Yes. On the US App Store, EQfy - Louder Volume is listed as Volume Booster Sound Amplifier, and the listing name can differ in other countries. It's the same app: open it on the App Store.

EQfy is built for iPhone and requires iOS 16 or later. The app is available in 25 languages.

Volume Boost goes from 100% to 200%, which adds up to +12 dB of gain on top of your iPhone volume for songs played in EQfy. Use it moderately. Learn more in how to make your iPhone louder than max volume and is volume boosting safe.

Yes. EQfy's tools apply to everything EQfy plays, whether you listen through the iPhone speaker, wired headphones or AirPods. For more tips, see how to make AirPods louder.

iOS sandboxing only lets EQfy process audio played inside EQfy. It can't boost Spotify, YouTube, Apple Music streaming, Netflix, phone or FaceTime calls, notifications or the system volume. For fixes that help everywhere, see iPhone volume too low.

Songs from an Apple Music subscription, and other protected files, play in EQfy, but the enhancement tools aren't available for them because iOS doesn't allow apps to process protected audio. Purchased or unprotected songs from your Music library and files you import from Files work with every tool.

Bass Boost adds up to +12 dB with a low-shelf boost centered around 200 Hz, tuned so small iPhone speakers can actually reproduce it. It's part of Premium. See how to boost bass on iPhone.

Seven bands (32 Hz, 64 Hz, 200 Hz, 500 Hz, 1 kHz, 4 kHz and 16 kHz) plus a preamp, 9 presets (Rock, Jazz, Electronic, Classical, Reggae, Rap, R&B, Dance and Acoustic), a Custom setting and a Reset button. See the best EQ settings for iPhone by genre.

It's an in-app effect with two modes: Reverb, with 9 room, hall and chamber presets, and 3D Source, which moves the sound around you with 4 Auto Motion patterns (bilateral, orbit, figure-eight and breathing) and can use head tracking with supported AirPods. It isn't Apple Spatial Audio or Dolby Atmos. 3D audio on iPhone, explained covers the difference.

For songs played in EQfy, the Headphones tab has a left/right audio balance slider with a Centre button to reset it. See how to fix left/right headphone balance on iPhone.

Yes, with Premium. You can set playback speed from 0.5× to 2×, save and share the enhanced audio file, and use the haptic player, which makes your iPhone vibrate to the beat.

AI Studio has four tools: Music Generator (compose a song from a text prompt, with an optional Force instrumental switch), Sound Effects, Text to Speech and Noise Reducer. All of them need an internet connection. Read the AI song generator guide.

AI Studio is credit-based. Premium includes Music Generator, Sound Effects and Text to Speech; without Premium these tools use credits, and credit packs are available in the app. Noise Reducer always uses credits, for subscribers too.

Premium unlocks Bass Boost, the 7-band equalizer, headphone balance, 3D Audio, playback speed, the haptic player and export, and includes Music Generator, Sound Effects and Text to Speech in AI Studio. Volume Boost and the music player stay free for everyone.

Premium is a weekly or yearly subscription. In the US it costs $1.99 per week or $27.99 per year; prices vary by country, and the App Store shows your local price before you confirm. Eligible plans start with a free trial.

Subscriptions are billed and managed by Apple. On your iPhone, open Settings, tap your name, tap Subscriptions, choose the EQfy subscription and tap Cancel Subscription. Apple explains the steps in Cancel a subscription from Apple.
