Extra Volume Booster for iPhone

Extra Volume Booster — Robust Sound Amplifier for iPhone

Extra Volume Booster is an iPhone app built to raise the loudness of quiet audio. It targets low-volume tracks and soft microphone output so music, voice notes, and recordings can be heard more clearly.

Main Capabilities

• Amplifies very low-level audio by a substantial amount — advertised boosts reach as high as 1000% or more.
• Improves playback from weak microphones and faint recordings so dialogue and details become easier to follow.
• Preserves audio clarity while increasing gain, minimizing the harsh artifacts that can come from simple amplification.

Quality and Performance

The app emphasizes increasing volume without introducing noticeable distortion. That means louder output while retaining a clean, intelligible sound—useful for those with hearing difficulty or for boosting faint voice memos and low-volume tracks.

Subscription Plans and Renewal Policy

• One-time lifetime unlock (single payment for permanent access).
• Annual subscription at $26.99 per year.
• Monthly subscription at $6.99 per month.

Subscriptions typically auto-renew. To stop future charges, turn off automatic renewal in your Apple account’s subscription or payment settings before the current period ends.

Alternative Recommendation

If you want another option, consider eSound — MP3 Music Player (Free) as a top suggested alternative for music playback with volume control features.

Quick Verdict

Extra Volume Booster is worth trying if you need a straightforward tool to make quiet audio usable without sacrificing clarity. Test it on a few sample files to confirm it meets your needs before committing to a paid plan.
