Launched April 2025. - Updated June 2025. > **Cadence:** 1 total versions · 0 majors in last 6 months · 331 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Cuspart: SMS Blocker is an established utilities app that is completely free. > **Bottom Line:** The app's privacy-first architecture is a strong differentiator, but the lack of social proof is a critical growth bottleneck, so the PM should prioritize user acquisition to establish a baseline rating. **Best for:** Mobile users seeking to organize SMS inboxes and filter spam through local, privacy-centric tools. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] [HIGH IMPACT] Implement a user-acquisition campaign because the current zero-rating status prevents organic discovery → increase install velocity — *The app has zero ratings, which is the primary barrier to trust and discovery on the App Store.* _(trade-off: deprioritize Pause feature development on non-essential UI tweaks — acquisition is the immediate priority.)_ ### Feature Gaps vs Competitors - AI-driven storage analysis (available in Cleaner AI) - Secure private vaults (available in Cleaner AI) - Wireless device-to-device transfer (available in Air Share) ### Outlook: Stable The utility market is consolidating around apps that offer multi-functional suites, leaving single-purpose tools like SMS Blocker exposed. Future success depends on establishing a user base through aggressive acquisition, as the current lack of social proof prevents the app from competing with established incumbents. - ⚪ The app maintains a basic feature set without recent expansion, signaling a focus on core stability over rapid growth. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Total Reviews | 0 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 2 analyzed | | Trend | Stable | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Cuspart: SMS Blocker** (this app) | N/A/5 | N/A | Mustafa Tolga DALBUDAK | | [Mach Drive - Cloud File Manager](https://marlvel.ai/apps/mach-drive-cloud-file-manager) | 4.3/5 | N/A | Mach Software Design | | [Photo to PDF: Converter Plus](https://marlvel.ai/apps/photo-to-pdf-converter-plus) | 4.3/5 | N/A | Bart Jacobs | | [Word to PDF Converter Plus](https://marlvel.ai/apps/word-to-pdf-converter-plus) | 5.0/5 | N/A | Bart Jacobs | | [Air Share: Backup or Copy Data](https://marlvel.ai/apps/air-share-backup-or-copy-data) | 4.5/5 | N/A | Dropouts Technologies LLP | | [Photos to PDF Fast Converter](https://marlvel.ai/apps/photos-to-pdf-fast-converter) | 4.7/5 | N/A | Dropouts Technologies LLP | ## Company Profile - **Developer:** Mustafa Tolga DALBUDAK ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/cuspart-sms-blocker/id6661027377?uo=4) - **Sources:** App store metadata. ## Related Intel Reports - [*Mach Drive - Cloud File Manager*](https://marlvel.ai/apps/mach-drive-cloud-file-manager) (Mach Software Design) — 4.3/5 Rating | N/A Sentiment - [*Photo to PDF: Converter Plus*](https://marlvel.ai/apps/photo-to-pdf-converter-plus) (Bart Jacobs) — 4.3/5 Rating | N/A Sentiment - [*Word to PDF Converter Plus*](https://marlvel.ai/apps/word-to-pdf-converter-plus) (Bart Jacobs) — 5.0/5 Rating | N/A Sentiment - [*Air Share: Backup or Copy Data*](https://marlvel.ai/apps/air-share-backup-or-copy-data) (Dropouts Technologies LLP) — 4.5/5 Rating | N/A Sentiment - [*Photos to PDF Fast Converter*](https://marlvel.ai/apps/photos-to-pdf-fast-converter) (Dropouts Technologies LLP) — 4.7/5 Rating | N/A Sentiment - [*Convert, Edit - PDF is Love*](https://marlvel.ai/apps/convert-edit-pdf-is-love) (Dropouts Technologies LLP) — N/A Rating | N/A Sentiment - [*Cleanse: Storage & Photo Clean*](https://marlvel.ai/apps/cleanse-storage-photo-clean) (CODEJOY TECHNOLOGY LIMITED) — 5.0/5 Rating | N/A Sentiment - [*PDF Reader PDF Viewer & Editor*](https://marlvel.ai/apps/pdf-reader-pdf-viewer-editor) (ZipoApps) — 2.6/5 Rating | N/A Sentiment - [*Sign PDF by Certificate*](https://marlvel.ai/apps/sign-pdf-by-certificate) (JIRI CHOMAT) — N/A Rating | N/A Sentiment - [*Seekee: Cloud Drive & AI Chat*](https://marlvel.ai/apps/com-wonder-aiai) (Vedat Yildiz) — 3.0/5 Rating | N/A Sentiment ## 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.
