The absence of recent updates (978 days since last store update) signals a lack of competitive pressure in this specific clinical workflow segment. ## Monetization Strategy - **Model:** Free - **Tiers:** Free access to all clinical tools and resources - **Analysis:** InvoSurg operates as a free professional utility, serving as a brand-building and recruitment funnel for InvoSurg, Inc. ## SWOT Analysis {#swot} **Core Strengths:** - Specialized clinical utility (DO2 calculator) functions as a B2B distribution barrier into cardiac surgery departments. **Growth Levers:** - Integration of real-time clinical data feeds could differentiate InvoSurg from static, document-based competitors. ## What's New - **Latest (v3.0.0, 2 years ago):** Introduced a staff demand calculator, InvoSurg job board, and opt-in push notifications, while consolidating ECLS resources. ## App Momentum (Zombie) {#momentum} - Dormant development for 32 months. - Last major release January 2024. > **Cadence:** 1 total versions · 1 majors in last 6 months · 978 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} InvoSurg is a medical app that is completely free. It holds a 4.33/5 rating from 12 reviews. > **Bottom Line:** InvoSurg provides specialized clinical value, but the 32-month development silence undermines its reliability as a medical reference tool. Addressing the clinical accuracy of the existing library would restore trust, but the lack of active development suggests the product is no longer a priority for the developer. **Best for:** Clinicians and perfusionists working in cardiac surgery and extra corporeal life support. ### PM Action Plan (Next Best Moves) - [ ] [MAINTAIN] Audit clinical guidelines for accuracy because the 32-month update gap risks providing outdated medical information to clinicians → maintain professional credibility. ### Outlook: Declining The outlook for InvoSurg is declining as the product remains in a maintenance-only state without updates to its core clinical content. In a medical context, the inability to provide current, evidence-based guidelines will inevitably lead to user churn as clinicians migrate to more reliable, frequently updated digital resources. - 🔴 The 978-day update gap indicates a zombie development state, which erodes user trust in the accuracy of clinical guidelines. - 🔴 Static, unmaintained resource libraries are increasingly vulnerable to more current, web-based clinical alternatives that provide real-time updates. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.33/5 | | Total Reviews | 12 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **InvoSurg** (this app) | 4.33/5 | N/A | InvoSurg, Inc. | | [VetCore: Pet Health Records](https://marlvel.ai/apps/vetcore-pet-health-records) | N/A/5 | N/A | Dmitriy Motorin | | [필잇 - 약 알림 및 복용 기록](https://marlvel.ai/apps/app--35) | N/A/5 | N/A | Hansub Yoo | | [레어노트 - 암·희귀질환 정보](https://marlvel.ai/apps/app--629) | 5.0/5 | N/A | LifeX, Inc. | | [창고형약국 약값체크](https://marlvel.ai/apps/com-hiddenwave-yakcheck) | N/A/5 | N/A | Lowkeybase | | [용인세브란스병원](https://marlvel.ai/apps/com-severance-newys) | 1.9/5 | N/A | Yonsei University Health System | ## Company Profile - **Developer:** InvoSurg, Inc. ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/invosurg/id1480250400?uo=4) - **Sources:** App store metadata. ## Related Intel Reports - [*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.
