(Strategic Takeaway) {#so-what} Secure Vault: Hide Files is an utilities app. With a 4.33/5 rating from 216 reviews, it draws more critical themes in recent reviews than its store average suggests. > **Bottom Line:** Secure Vault: Hide Files relies on its calculator disguise to retain users, but critical playback failures and billing complaints invalidate the current value proposition. Addressing these technical and trust barriers is required to prevent total churn to native platform alternatives. **Best for:** Users seeking to hide sensitive personal files, photos, and documents from unauthorized access on their mobile devices. ### PM Action Plan (Next Best Moves) - [ ] [PIVOT] Audit billing flow because users report deceptive lifetime charges → reduce negative sentiment ### Outlook: Declining The privacy utility market is shifting toward native, system-level security features that do not require third-party trust. Secure Vault: Hide Files is poorly positioned to compete with these native tools, as its current technical instability and billing complaints accelerate user migration to more reliable alternatives. - 🔴 Technical failures preventing media export erode the core utility, which compounds the distrust already visible in user reviews. - 🔴 The 24-month update silence suggests a maintenance-only posture, leaving the app vulnerable to native platform security updates. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.33/5 | | Total Reviews | 216 | | Sentiment | Frustrated (25/100) | | Confidence | Medium | | Pricing Model | Subscription | | Platforms | iOS | | Key Features | 3 analyzed | | Trend | Stable | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Secure Vault: Hide Files** (this app) | 4.33/5 | Frustrated | Nikmesoft Company, Ltd. | | [Sota Connect: Secure Network](https://marlvel.ai/apps/fi-catconnect-sota) | 4.9/5 | 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 | | [Free VPN by Free VPN .org™](https://marlvel.ai/apps/free-vpn-by-free-vpn-org) | 4.5/5 | Mixed | Free VPN LLC | | [Fusvob VPN : Super VPN 2026](https://marlvel.ai/apps/com-toplinkc-foxexcellent) | 4.5/5 | Mixed | Fuxin Technology | ## Company Profile - **Developer:** Nikmesoft Company, Ltd. - **Website:** [https://calculatorz.nikmesoft.com](https://calculatorz.nikmesoft.com) ## Data Sources & Links - **App Store ID:** 1613922800 - **Dev Site:** [Official Website](https://calculatorz.nikmesoft.com) - **Sources:** Developer website content, App store metadata, User reviews. ## Related Intel Reports - [*Sota Connect: Secure Network*](https://marlvel.ai/apps/fi-catconnect-sota) (Cat Connect) · 4.9/5 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 - [*Free VPN by Free VPN .org™*](https://marlvel.ai/apps/free-vpn-by-free-vpn-org) (Free VPN LLC) · 4.5/5 Rating - [*Fusvob VPN : Super VPN 2026*](https://marlvel.ai/apps/com-toplinkc-foxexcellent) (Fuxin Technology) · 4.5/5 Rating - [*Potatso*](https://marlvel.ai/apps/potatso) (Potatso Lab LTD) · 4.4/5 Rating - [*Quantumult X*](https://marlvel.ai/apps/quantumult-x) (Cross Utility Ltd) · 3.8/5 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 ## Frequently Asked Questions {#faq} ### Is Secure Vault: Hide Files safe for sensitive data?
