Best volume booster app for iPhone

Updated — ratings read from App Store data for the US storefront on September 21, 2026.

The short answer: the best volume booster app for iPhone is Volume Booster — Loud Bass EQ, ad-free at every tier, with gain, a bass dial and a 6-band equalizer for your own audio. On iPhone no app can raise the system volume past the hardware maximum, so every "volume booster" on the App Store is a player that amplifies the audio it plays itself. That one fact decides the whole list: if a specific recording is quiet, a booster is the right tool; if your phone got quieter over time, four free settings fix it and you need no app.

Start with what is quiet

The full list is below. These three cases cover almost everyone who searches for a booster.

The whole phone is quiet

No app needed. Late Night EQ on, Sound Check off, Spotify set to Loud, speaker grille brushed clean. Free, two minutes, works everywhere on the phone.

How to make your iPhone louder

One recording is quiet

A booster is the right tool. A podcast mastered well below commercial music stays quiet no matter how clean the grille is. Gain plus an equalizer is the only thing that adds level.

The equalizer, explained

A quiet video on a laptop

Browser extension, carefully. On desktop an extension really can exceed 100% on tab audio — but read the permissions before installing one.

Download on the App Store Volume Booster — Loud Bass EQ — free to try, no ads at any tier.

  1. #1 Volume Booster — Loud Bass EQ

    Best overall · Our app · Free to try · iOS

    Our pick for a quiet recording on iPhone. A player that applies gain, a bass dial and a 6-band equalizer to your own music library and audio files, with no ads at any tier, processing on the device, and a capped gain instead of an invented percentage. It is free to try, and it says plainly what iOS does not let any app do.

    Pros
    • No ads, on any tier
    • Processing happens on the device
    • Says plainly what it cannot do
    Cons
    • iOS only for now
    • Cannot boost Spotify, YouTube or system volume
    • Subscription after the trial
    Download on the App Store

  2. #2 No app at all — four iOS settings

    Good if the whole phone got quieter · Free

    Late Night EQ on, Sound Check off, Spotify’s volume level set to Loud, and a clean speaker grille. These recover loudness that something was taking away, which is the actual problem in a large share of cases, and they cost nothing.

    Pros
    • Works across every app on the phone
    • Two minutes, no download
    • Nothing to cancel
    Cons
    • Recovers lost loudness, never adds level
    • Will not rescue a quietly mastered recording

  3. #3 Volume Booster Bass Booster (M. Y. Özdemir)

    Good if you want the most-rated option

    The most-rated app in this search on the US App Store. Same structural limit as every other entry here. We have not audited its monetisation — check the In-App Purchases line on the listing and the recent reviews before you commit.

    Pros
    • Large, long-running review base
    Cons
    • Monetisation not audited by us
    • Same iOS limits as every booster

  4. #4 Bass Booster EQ + Volume Boost (Plane Cubes)

    Good if you mainly want bass

    Positioned around bass rather than raw loudness, which is often the better answer: perceived loudness rises when the bottom end comes up, without pushing the whole signal into distortion.

    Pros
    • Bass-led approach suits music listening
    Cons
    • Monetisation not audited by us
    • Same iOS limits as every booster

  5. #5 Bass Booster Volume Boost EQ (Companjen Apps)

    Good if you want a second opinion

    A veteran of the category with a comparable rating base. Worth installing alongside one other app and comparing on the same file — the difference between boosters is mostly equalizer quality and how gracefully they handle clipping.

    Pros
    • Established track record
    Cons
    • Monetisation not audited by us
    • Same iOS limits as every booster

  6. #6 Browser volume booster extensions

    Good if the audio is on a laptop · Desktop only

    On desktop an extension can genuinely raise tab audio above 100%. The trade is permissions: a tab-audio extension usually asks to read and change data on every site you visit. In June 2025 researchers at LayerX reported four volume booster extensions — more than a million users between them — that could load instructions from a remote server and run them.

    Pros
    • Actually exceeds 100% on browser audio
    • No purchase
    Cons
    • Broad permissions on every site
    • Some found able to run remote code

Our pick: Volume Booster — Loud Bass EQ, for quiet recordings on iPhone.

How we picked

Ranking boosters by claimed loudness is meaningless, because every one of them is bound by the same rule: iOS does not let an app raise the system volume, so each app can only amplify the audio it plays itself. Two apps with identical marketing differ in equalizer quality, how they handle clipping when you push the gain, and how much of the screen goes to advertising — not in how loud the phone can get.

So the order here starts from a different question: is an app the right answer at all? For a podcast or voice memo mastered far below commercial music, an app is the only thing that helps, and ours comes first because it does that with no ads and a capped gain. For a phone that has quietly lost volume over a year, an app usually is not the answer, which is why the free settings sit right behind it. The full explanation of why the ceiling exists is in how it works, and the measured version of the question is in do volume booster apps actually work.

Before subscribing to anything, it is worth checking that the problem is the audio and not the hardware: the sound test and headphone test take under a minute and will tell you if one speaker is blocked or a channel has dropped out.

Common questions

What is the best volume booster app for iPhone?

Our pick is Volume Booster — Loud Bass EQ: it adds gain, a bass dial and a 6-band equalizer to your own files and library audio, with no ads at any tier and processing on the device. That is the right tool when a recording is quiet. If the phone itself got quieter, start with the free fixes — Late Night EQ, Sound Check off and a clean speaker grille. The most-rated App Store alternatives (Volume Booster Bass Booster, Bass Booster EQ + Volume Boost) work within the same iOS limits if you want a second opinion.

Can any iPhone app raise the system volume above maximum?

No. iOS does not expose the system volume ceiling to apps, so nothing on the App Store can push your phone past its hardware maximum or reach into Spotify, YouTube or the phone earpiece. What a booster can do is amplify the audio it plays itself. Any listing promising a "200% system boost" is describing something the operating system does not permit.

How do I judge a volume booster app in thirty seconds?

Read the In-App Purchases line on the listing, then sort the reviews by most recent. The two complaints that matter are "it did nothing to Spotify", which means the listing over-promised, and ad volume. Beyond that the differences come down to equalizer quality and how the app handles clipping when you push the gain.

Are free volume booster apps safe?

On the App Store the usual cost is wasted time rather than harm, because apps are reviewed and sandboxed. Browser extensions are a different risk profile: they typically request permission to read and change data on every site you visit, and in June 2025 researchers at LayerX reported four volume booster extensions on the Chrome Web Store, with more than a million users between them, that could load instructions from a remote server and run them.

Will boosting the volume damage my speakers or hearing?

Phone speakers distort well before they break, so the audible warning arrives first — back the gain off when the sound gets harsh. Hearing is the real risk: sustained listening above roughly 85 dB causes cumulative damage, and boosted headphone audio gets there easily. Use the boost to make quiet material audible, not to make loud material louder.

How were these picked?

Ratings and rating counts were read from the public App Store data for the US storefront on 21 September 2026. We did not rank on claimed loudness, because every app in the category operates under the same iOS limit; we ranked on how well each option fixes a quiet recording on iPhone, then on how transparent it is about what it does. Ours comes first on both: no ads at any tier, a capped gain, and a plain statement of what iOS does not allow. The free settings come second because they fix a phone that got quieter over time.
