(Strategic Takeaway) {#so-what} TNM Cancer Staging Calculator is an education app. It holds a 4.67/5 rating from 3 reviews. > **Bottom Line:** Maintaining the clinical verification cadence is the primary defense against generalist medical apps, as the staging-only focus rests entirely on the accuracy of the AI-verified update loop. **Best for:** Oncologists, medical residents, nurses, and students requiring rapid, verified access to cancer staging criteria. ### PM Action Plan (Next Best Moves) - [ ] [PIVOT] A/B test student-specific pricing because the $2.99/month tier lacks a clear value proposition for residents → increase conversion velocity ### Outlook: Stable The clinical reference market is consolidating around apps that provide verified, offline-accessible data. TNM Cancer Staging Calculator is well-positioned, but the reliance on a manual verification team to validate AI-extracted updates creates a scaling bottleneck that could be exploited by faster-moving generalist rivals. - 🟢 The 3-day update cadence demonstrates active feature investment, ensuring the staging criteria remain current for clinical use. - ⚪ The shift to a three-tier subscription model suggests the developer is testing price sensitivity among professional users. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.67/5 | | Total Reviews | 3 | | Sentiment | Thrilled (90/100) | | Confidence | Medium | | Pricing Model | Subscription | | Platforms | iOS & Android | | Key Features | 3 analyzed | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **TNM Cancer Staging Calculator** (this app) | 4.67/5 | Thrilled | Rishabh Kumar | | [Catbus Student](https://marlvel.ai/apps/catbus-student) | 4.3/5 | N/A | Cohota Join Stock Company | | [Money Matrix (CAD)](https://marlvel.ai/apps/money-matrix-cad) | 5.0/5 | N/A | Blooming Kids Software LLC | | [Quran Treasure Island for Kids](https://marlvel.ai/apps/quran-treasure-island-for-kids) | 4.9/5 | Mixed | Akeela Manekia | | [Valencia College - MyVC](https://marlvel.ai/apps/valencia-college-myvc) | 5.0/5 | N/A | Valencia College | | [Verbi: Learn a New Language](https://marlvel.ai/apps/verbi-learn-a-new-language) | 4.3/5 | n/a | ACADIA LABS INC. | ## Company Profile - **Developer:** Rishabh Kumar - **Website:** [https://cancer-staging-app.web.app](https://cancer-staging-app.web.app) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/tnm-cancer-staging-calculator/id6755624017?uo=4) - **Google Play:** [View on Google Play](https://play.google.com/store/apps/details?id=com.tnm.cancerstaging&hl=en&gl=us) - **Dev Site:** [Official Website](https://cancer-staging-app.web.app) - **Sources:** Developer website content, App store metadata, User reviews. ## Related Intel Reports - [*Catbus Student*](https://marlvel.ai/apps/catbus-student) (Cohota Join Stock Company) · 4.3/5 Rating - [*Money Matrix (CAD)*](https://marlvel.ai/apps/money-matrix-cad) (Blooming Kids Software LLC) · 5.0/5 Rating - [*Quran Treasure Island for Kids*](https://marlvel.ai/apps/quran-treasure-island-for-kids) (Akeela Manekia) · 4.9/5 Rating - [*Valencia College - MyVC*](https://marlvel.ai/apps/valencia-college-myvc) (Valencia College) · 5.0/5 Rating - [*Verbi: Learn a New Language*](https://marlvel.ai/apps/verbi-learn-a-new-language) (ACADIA LABS INC.) · 4.3/5 Rating - [*자주 틀리는 우리말*](https://marlvel.ai/apps/app--424) (DaolSoft, Co., Ltd.) · N/A Rating - [*달공부 - 한 달 공부 다이어리 + 루틴/공부 타이머*](https://marlvel.ai/apps/azlabs-dalstudy) (SuWon Choi) · N/A Rating - [*타요콘 - 타요 아바타 놀이동화*](https://marlvel.ai/apps/com-kigle-project-tayocon) (KIGLE) · 3.1/5 Rating - [*천자문 워치*](https://marlvel.ai/apps/app--385) (kim juyoung) · N/A Rating - [*천자문 공부 도우미*](https://marlvel.ai/apps/app--382) (kim juyoung) · 5.0/5 Rating ## 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.
