The rivals identified
Nemeses(1)
This app directly targets the same utility-seeking user base by offering identical volume amplification and Bluetooth-specific audio enhancement features.
Same space(4)
While focused on speaker maintenance, it overlaps with the target app by addressing audio quality issues through frequency-based utilities.
Differentiators
- Provides unique sonic water ejection technology, solving a specific hardware pain point that volume boosters ignore.
- Includes a built-in decibel meter and frequency tuning tools, positioning the app as a professional audio diagnostic utility.
This app targets the same demographic by marketing 'super loud' amplification and additional voice-specific audio enhancement features.
This app competes by bundling volume amplification with bass-specific equalization, targeting users who want audio quality improvements alongside loudness.
Differentiators
- Integrates a dedicated bass equalizer, offering a more comprehensive audio customization suite than basic volume boosters.
- Utilizes system-wide audio integration to ensure consistent performance across various media playback applications on Android.
A long-standing utility that competes for the same audience by focusing on raw audio gain control and hardware compatibility.
Differentiators
- Maintains a massive install base of over one million reviews, creating a significant social proof barrier.
- Focuses on hardware-specific compatibility settings that provide granular control over device-specific audio output limitations.
New entrants(2)
This app enters the space by focusing on the physical maintenance of speakers, a common pain point for the target app's user base.
This newcomer captures the same 'utility-seeking' audience by using sound-based triggers for phone management.

The outtake for Sound Booster・Increase Volume
Strengths to defend, gaps to attack
Core Strengths
- One-tap interface lowers barrier to entry for casual users
- Hi-Res audio support provides technical differentiator for audiophiles
Critical Frictions
- Premium tier at $29.99/year exceeds category median
- Inconsistent volume output performance triggers negative feedback
Growth Levers
- Untapped B2B partnerships for audio-accessibility tools
- Integration of hardware-specific diagnostic features
Market Threats
- Ad-heavy free tier invites churn to utility-focused rivals
- Maintenance-mode update cadence leaves app vulnerable to live-ops competitors
What are the next best moves?
Audit ad-trigger logic because users report ads without functional volume boost → reduce churn
Top complaint theme identifies ad-delivery without utility as a primary frustration driver.
Trade-off: Pause the UI redesign sprint — ad-logic stability has higher retention impact than visual polish.
Ship hardware-specific compatibility settings because competitors use them to build moats → improve performance
Volume Booster GOODEV uses granular hardware settings to maintain a high-barrier install base.
Trade-off: Push the Hi-Res audio expansion to Q4 — hardware compatibility is a higher-frequency user need.
A counter-intuitive read
The app's high rating is a lagging indicator; the ad-delivery-without-utility complaint is a leading indicator of churn that will erode the #133 grossing rank by Q3.
Feature Gaps vs Competitors
- Sonic water ejection technology (available in Fix My Speakers but absent here)
- Dedicated bass equalizer (available in Speaker Volume: Bass Booster but absent here)
Key Takeaways
Sound Booster holds its category lead through a simple interface but bleeds users to ad-heavy performance failures, so revenue growth hinges on tightening the core utility trigger before the annual subscription gate.
Where Is It Heading?
Mixed Signals
The audio utility market is consolidating around apps that offer hardware-specific diagnostics and cleaner ad-to-utility ratios. Sound Booster remains exposed to churn because its current update cadence lacks the feature expansion needed to defend against specialized rivals.
Persistent ad-delivery without functional audio enhancement triggers user frustration, which will accelerate churn toward utility-focused competitors.
Recent updates focus on stability and bug fixes, signaling a maintenance-mode posture that leaves the app exposed to live-ops rivals.
