The lack of updates for 345 days suggests a maintenance-only or abandoned posture, limiting its competitive viability against active medical reference tools. ## Monetization Strategy - **Model:** Free - **Tiers:** Free access to all calculation tools - **Analysis:** ClinCalc operates as a free utility with no visible monetization or subscription gates. ## SWOT Analysis {#swot} **Core Strengths:** - Standardized clinical formulas provide reliable reference - Free access removes barriers for professionals **Growth Levers:** - Integration of patient-data export to reduce manual entry ## What's New - **Latest (v1.1.3, 11 months ago):** Updated the Mifflin St Jeor equation for improved calculation accuracy and added informational notes for AIBW, MSJ, and Penn State. ## App Momentum (Zombie) {#momentum} - Last major release 11 months ago. - Zero feature updates in 2026. > **Cadence:** 1 total versions · 1 majors in last 6 months · 345 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} ClinCalc is a medical app that is completely free. It holds a 5/5 rating from 3 reviews. > **Bottom Line:** ClinCalc's 11-month dormancy invalidates its value as a clinical reference tool, as medical accuracy requires consistent updates. The PM should sunset the app if maintenance cannot be resumed, as stale medical data creates a liability risk for clinical users. **Best for:** Clinical professionals and nutritionists requiring quick access to standardized energy and protein calculation formulas. ### PM Action Plan (Next Best Moves) - [ ] [MAINTAIN] Audit clinical formula accuracy because the app has been silent for 11 months → maintain professional trust ### Outlook: Declining The medical utility market is consolidating around tools that provide frequent, verified updates to clinical formulas. ClinCalc's current dormant state leaves it exposed to more active competitors, and the lack of a clear path to maintenance suggests a declining outlook for its professional utility. - 🔴 The 345-day update gap suggests the app is in a zombie state, which erodes professional trust in its clinical accuracy. - 🔴 Lack of active development leaves the app vulnerable to rivals that offer more frequent updates and broader clinical reference notes. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 5/5 | | Total Reviews | 3 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **ClinCalc** (this app) | 5/5 | N/A | Peter Weiss | | [BabyMeasure: Growth Tracker](https://marlvel.ai/apps/babymeasure-growth-tracker) | N/A/5 | N/A | Emre HAMURCU | | [Lace Pro](https://marlvel.ai/apps/lace-pro) | 4.6/5 | Excited | Neurotone AI | | [Medical Abbreviations: Quick](https://marlvel.ai/apps/medical-abbreviations-quick) | 4.0/5 | Excited | VLR Software | | [Nursing Home Check](https://marlvel.ai/apps/nursing-home-check) | 4.0/5 | N/A | Alona Nesterenko | | [VetCore: Pet Health Records](https://marlvel.ai/apps/vetcore-pet-health-records) | N/A/5 | N/A | Dmitriy Motorin | ## Company Profile - **Developer:** Peter Weiss ## Data Sources & Links - **App Store ID:** 6739016756 - **Sources:** App store metadata. ## Related Intel Reports - [*BabyMeasure: Growth Tracker*](https://marlvel.ai/apps/babymeasure-growth-tracker) (Emre HAMURCU) · N/A Rating - [*Lace Pro*](https://marlvel.ai/apps/lace-pro) (Neurotone AI) · 4.6/5 Rating | Positive Sentiment - [*Medical Abbreviations: Quick*](https://marlvel.ai/apps/medical-abbreviations-quick) (VLR Software) · 4.0/5 Rating | Positive Sentiment - [*Nursing Home Check*](https://marlvel.ai/apps/nursing-home-check) (Alona Nesterenko) · 4.0/5 Rating - [*VetCore: Pet Health Records*](https://marlvel.ai/apps/vetcore-pet-health-records) (Dmitriy Motorin) · N/A Rating - [*필잇 - 약 알림 및 복용 기록*](https://marlvel.ai/apps/app--35) (Hansub Yoo) · N/A Rating - [*레어노트 - 암·희귀질환 정보*](https://marlvel.ai/apps/app--629) (LifeX, Inc.) · 5.0/5 Rating - [*창고형약국 약값체크*](https://marlvel.ai/apps/com-hiddenwave-yakcheck) (Lowkeybase) · N/A Rating - [*용인세브란스병원*](https://marlvel.ai/apps/com-severance-newys) (Yonsei University Health System) · 1.9/5 Rating - [*1001Doktor*](https://marlvel.ai/apps/com-binbirdoktor-binbirdoktor) (1001Doktor Ltd.
