Its lack of updates for over 1,000 days positions it as a static clinical asset rather than an active market competitor. ## Monetization Strategy - **Model:** Free - **Tiers:** Free - **Analysis:** The app is distributed as a free tool to support an IRB-approved medical study at the UCSD School of Medicine. ## 🟢 User Sentiment (Low Confidence: 10 of 10 reviews analyzed) {#user-sentiment} - **Overall Rating:** 4.26/5 - **Platform Split:** iOS 4.3/5 (27 ratings) - **Overall Sentiment:** Excited ### Top Praises - **Step by step emergency instructions provide critical guidance for users during high-stress medical situations** - **Expert-developed medical protocols ensure users follow accurate timing for chest compressions and emergency response** ### Top Complaints (Impact Areas) - **Application crashes during simulated resuscitation scenarios render the tool unusable when users need it most** ## SWOT Analysis {#swot} **Core Strengths:** - IRB-approved clinical study status establishes medical authority - Rhythmic pacing protocols provide critical guidance during high-stress events **Growth Levers:** - Expansion into child-specific CPR protocols to address the gap left by removed content ## What's New - **Latest (v2.4, 2 years ago):** Added Spanish language support and refined emergency instructions for choking, vomiting, and drowning scenarios. ## App Momentum (Zombie) {#momentum} - No updates for 34 months. - Maintains static clinical research status. > **Cadence:** 1 total versions · 1 majors in last 6 months · 1028 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Rescue Me CPR! is a market-leading medical app that is completely free. With a 4.26/5 rating from 27 reviews, it delivers strong user satisfaction. > **Bottom Line:** Rescue Me CPR! provides life-saving protocols that users value, but the persistent simulation crashes negate its primary purpose. Addressing stability is the only way to restore trust and ensure the tool functions when users need it most. **Best for:** Untrained individuals seeking emergency medical guidance and participants in the UCSD School of Medicine study. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Rebuild simulation engine stability because crashes during active CPR render the tool unusable → restore core utility ### Outlook: Declining Rescue Me CPR! remains in a dormant state with no updates for nearly three years, effectively functioning as a static research artifact. Without a return to active development, the app will continue to lose utility as mobile operating systems evolve, eventually rendering it incompatible with current hardware. - 🔴 Persistent application crashes during active simulations → render the tool unusable during emergencies → erode user trust in the clinical protocol. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.26/5 | | Total Reviews | 27 | | Sentiment | Excited (75/100) | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 2 analyzed | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Rescue Me CPR!** (this app) | 4.26/5 | Excited | Brennan Marsh-Armstrong | | [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 | | [1001Doktor](https://marlvel.ai/apps/com-binbirdoktor-binbirdoktor) | 4.8/5 | N/A | 1001Doktor Ltd.
