(Strategic Takeaway) {#so-what} KB Volume Lock & Limiter is an utilities app that is free with in-app purchases. It holds a 4/5 rating from 4 reviews. > **Bottom Line:** Resolving the post-uninstallation volume bug is the only way to stabilize the user base, as the current technical regression outweighs the utility of the volume-locking feature. Addressing this will unlock long-term retention and prevent further negative brand perception. **Best for:** Parents and caregivers managing audio levels for children, particularly those with autism or sensory processing sensitivities. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Audit and resolve persistent volume-lowering bug post-uninstallation because it is the top-cited technical complaint → restore brand trust ### Outlook: Mixed The market for parental control utilities is consolidating around stable, system-integrated solutions. KB Volume Lock & Limiter remains exposed due to its reliance on background-monitoring mechanisms that are prone to OS-level breakage and technical regressions. - 🔴 Persistent volume interference after uninstallation creates a negative feedback loop that erodes trust in the core utility. - ⚪ The 11-week maintenance cadence indicates a lack of active feature investment, leaving the app vulnerable to OS-level changes. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4/5 | | Total Reviews | 4 | | Sentiment | Mixed (50/100) | | Confidence | Low | | Pricing Model | Freemium | | Platforms | iOS | | Key Features | 3 analyzed | | Outlook | Mixed | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **KB Volume Lock & Limiter** (this app) | 4/5 | Mixed | Christopher Mayberry | | [Sota Connect: Secure Network](https://marlvel.ai/apps/fi-catconnect-sota) | 4.8/5 | N/A | Cat Connect | | [V2Box - V2ray Client](https://marlvel.ai/apps/v2box-v2ray-client) | 4.6/5 | n/a | techlaim | | [avoVPN Desktop](https://marlvel.ai/apps/avovpn-desktop) | N/A/5 | N/A | Avocado VPN Technologies | | [Fusvob VPN : Super VPN 2026](https://marlvel.ai/apps/com-toplinkc-foxexcellent) | 4.5/5 | Mixed | Fuxin Technology | | [VPN 365-Master WIFI Security](https://marlvel.ai/apps/vpn-365-master-wifi-security) | 4.6/5 | n/a | vpn fast | ## Company Profile - **Developer:** Christopher Mayberry ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/kb-volume-lock-limiter/id6749469745?uo=4) - **Sources:** App store metadata, User reviews. ## Related Intel Reports - [*Sota Connect: Secure Network*](https://marlvel.ai/apps/fi-catconnect-sota) (Cat Connect) · 4.8/5 Rating - [*V2Box - V2ray Client*](https://marlvel.ai/apps/v2box-v2ray-client) (techlaim) · 4.6/5 Rating - [*avoVPN Desktop*](https://marlvel.ai/apps/avovpn-desktop) (Avocado VPN Technologies) · N/A Rating - [*Fusvob VPN : Super VPN 2026*](https://marlvel.ai/apps/com-toplinkc-foxexcellent) (Fuxin Technology) · 4.5/5 Rating - [*VPN 365-Master WIFI Security*](https://marlvel.ai/apps/vpn-365-master-wifi-security) (vpn fast) · 4.6/5 Rating - [*카톡 분석 - 오픈채팅, 카톡 채팅 분석, 통계, 검색*](https://marlvel.ai/apps/com-liger-katalkanalysispaid) (Park Sung Cheol) · N/A Rating - [*로또 황금번호 생성기*](https://marlvel.ai/apps/lotto-lottogold) (jaehwan lee) · N/A Rating - [*도사폰 (만세력 역학도구)*](https://marlvel.ai/apps/app--656) (Softchaser Company Limited) · 5.0/5 Rating - [*근로자 공수달력*](https://marlvel.ai/apps/jaehwan-worktracer) (jaehwan lee) · N/A Rating - [*レジュメ*](https://marlvel.ai/apps/app--54) (Indeed Inc.) · 2.2/5 Rating ## Frequently Asked Questions {#faq} ### Is KB Volume Lock & Limiter safe for my child's device? The app provides volume-capping tools for parents, but users report technical issues where volume remains locked even after the app is uninstalled. It is not a replacement for parental supervision. ### Can I use the app for free? A free version is available, but it is limited to a 2-minute auto-disable timer. Full features like remote control and unlimited timers require a weekly subscription. ### What happens if I delete the app? Users report that volume reduction issues can persist on the device even after the application is uninstalled, which may require manual system volume adjustments. ## Methodology {#methodology} This report was generated by Marlvel.ai's 5-stage AI intelligence pipeline: 1. **Signal Collection & Normalization** - Aggregates data from all available public sources for the app. Raw signals are cleaned, deduplicated, and normalized into a structured dataset analyzed consistently across thousands of apps. 2. **Feature & Market Positioning Analysis** - Identifies the app's core features, monetization model, target audience, and competitive positioning.
